+The SameGame example can interface with a simple PHP script to store XML high score data on a remote server. We do not have a publically accessible server available for this use, but if you have access to a PHP capable webserver you can copy the files (score_data.xml, score.php, score_style.xsl) to it and alter the highscore_server variable at the top of the samegame.js file to point to it.

+\title Advanced Tutorial
+
+This tutorial goes step-by-step through creating a full application using just QML.
+It is assumed that you already know basic QML (such as from doing the simple tutorial) and the focus is on showing
+how to turn that knowledge into a complete and functioning application.
+
+This tutorial involves a significant amount of JavaScript to implement the game logic. An understanding of JavaScript is helpful to understand the JavaScript parts of this tutorial, but if you don't understand JavaScript you can still get a feel for how to integrate QML elements with backend logic which creates and controls them. From the QML perspective, there is little difference between integrating with backend logic written in C++ and backend logic written in JavaScript.
+
+In this tutorial we recreate, step by step, the Same Game demo in $QTDIR/demos/declarative/samegame.qml.
+The results of the individual steps are in the $QTDIR/examples/declarative/tutorials/samegame directory.

+\title Advanced Tutorial 1 - Creating the Game Canvas and Blocks
+
+The first step is to create the items in your application. In Same Game we have a main game screen and the blocks that populate it.
+
+\image declarative-adv-tutorial1.png
+
+Here is the QML code for the basic elements. The game window:
+
+\snippet declarative/tutorials/samegame/samegame1/samegame.qml 0
+
+This gives you a basic game window, with room for the game canvas. A new game
+button and room to display the score. The one thing you may not recognize here
+is the \l SystemPalette item. This item provides access to the Qt system palette
+and is used to make the button look more like a system button (for exact native
+feel you would use a \l QPushButton). Since we want a fully QML button, and QML does
+not include a button, we had to write our own. Below is the code which we wrote to do this:
+
+\snippet declarative/tutorials/samegame/samegame1/Button.qml 0
+
+Note that this Button component was written to be fairly generic, in case we
+want to use a similarly styled button later.
+
+And here is a simple block:
+
+\snippet declarative/tutorials/samegame/samegame1/Block.qml 0
+
+Since it doesn't do anything yet it's very simple, just an image. As the
+tutorial progresses and the block starts doing things the file will become
+more than just an image. Note that we've set the image to be the size of the item.
+This will be used later, when we dynamically create and size the block items the image will be scaled automatically
+to the correct size.
+
+You should be familiar with all that goes on in these files so far. This is a
+very basic start and doesn't move at all - next we will populate the game canvas
+with some blocks.

+/*!
+\page advtutorial2.html
+\title Advanced Tutorial 2 - Populating the Game Canvas
+
+Now that we've written some basic elements, let's start writing the game. The
+first thing to do is to generate all of the blocks. Now we need to dynamically
+generate all of these blocks, because you have a new, random set of blocks
+every time. As they are dynamically generated every time the new game button is
+clicked, as opposed to on startup, we will be dynamically generating the blocks
+in the JavaScript, as opposed to using a \l Repeater.
+
+This adds enough script to justify a new file, \c{samegame.js}, the intial version
+of which is shown below
+
+\snippet declarative/tutorials/samegame/samegame2/samegame.js 0
+
+The gist of this code is that we create the blocks dynamically, as many as will fit, and then store them in an array for future reference.
+The \c initBoard function will be hooked up to the new game button soon, and should be fairly straight forward.
+
+The \c createBlock function is a lot bigger, and I'll explain it block by block.
+First we ensure that the component has been constructed. QML elements, including composite ones like the \c Block.qml
+that we've written, are never created directly in script. While there is a function to parse and create an arbitrary QML string,
+in the case where you are repeatedly creating the same item you will want to use the \c createComponent function. \c createComponent is
+a built-in function in the declarative JavaScript, and returns a component object.
+A component object prepares and stores a QML element (usually a composite element) for easy and efficient use.
+When the component is ready, you can create a new instance of the loaded QML with the \c createObject method.
+If the component is loaded remotely (over HTTP for example) then you will have to wait for the component to finish loading
+before calling \c createObject. Since we don't wait here (the waiting is asyncronous, the component object will send a signal to tell
+you when it's done) this code will only work if the block QML is a local file.
+
+As we aren't waiting for the component, the next block of code creates a game block with \c{component.createObject}.
+Since there could be an error in the QML file you are trying to load, success is not guaranteed.
+The first bit of error checkign code comes right after \c{createObject()}, to ensure that the object loaded correctly.
+If it did not load correctly the function returns false, but we don't have that hooked up to the main UI to indicate
+that something has gone wrong. Instead we print out error messages to the console, because an error here means an invalid
+QML file and should only happen while you are developing and testing the UI.
+
+Next we start to set up our dynamically created block.
+Because the \c{Block.qml} file is generic it needs to be placed in the main scene, and in the right place.
+This is why \c parent, \c x, \c y, \c width and \c height are set. We then store it in the board array for later use.
+
+Finally, we have some more error handling. You can only call \c{createObject} if the component has loaded.
+If it has not loaded, either it is still loading or there was an error loading (such as a missing file).
+Since we don't request remote files the problem is likely to be a missing or misplaced file.
+Again we print this to the console to aid debugging.
+
+You now have the code to create a field of blocks dynamically, like below:
+
+\image declarative-adv-tutorial2.png
+
+To hook this code up to the \e{New Game} button, you alter it as below:
+
+\snippet declarative/tutorials/samegame/samegame2/samegame.qml 1
+
+We have just replaced the \c{onClicked: console.log("Implement me!")} with \c{onClicked: initBoard()}.
+Note that in order to have the function available, you'll need to include the script in the main file,
+by adding a script element to it.
+
+\snippet declarative/tutorials/samegame/samegame2/samegame.qml 2
+
+With those two changes, and the script file, you are now dynamically creating a field of blocks you can play with.
+They don't do anything now though; the next chapter will add the game mechanics.

+\page advtutorial3.html
+\title Advanced Tutorial 3 - Implementing the Game Logic
+
+First we add to the \c initBoard function clearing of the board before filling it up again, so that clicking new game won't leave the previous game
+lying around in the background. To the \c createComponent function we have added setting the type of the block to a number between
+one and three - it's fundamental to the game logic that the blocks be different types if you want a fun game.
+
+The main change was adding the following game logic functions:
+\list
+\o function \c{handleClick(x,y)}
+\o function \c{floodFill(xIdx,yIdx,type)}
+\o function \c{shuffleDown()}
+\o function \c{victoryCheck()}
+\o function \c{floodMoveCheck(xIdx, yIdx, type)}
+\endlist
+
+As this is a tutorial about QML, not game design, these functions will not be discussed in detail. The game logic here
+was written in script, but it could have been written in C++ and had these functions exposed in the same way (except probably faster).
+The interfacing of these functions and QML is what we will focus on. Of these functions, only \c handleClick and \c victoryCheck
+interface closely with the QML. Those functions are shown below (the rest are still in the code for this tutorial located at
+\c{$QTDIR/examples/declarative/tutorials/samegame}).
+
+\snippet declarative/tutorials/samegame/samegame3/samegame.js 1
+\snippet declarative/tutorials/samegame/samegame3/samegame.js 2
+
+You'll notice them referring to the \c gameCanvas item. This is an item that has been added to the QML for easier interfacing with the game logic.
+It is placed next to the background image and replaces the background as the item to create the blocks in.
+Its code is shown below:
+
+\snippet declarative/tutorials/samegame/samegame3/samegame.qml 1
+
+This item is the exact size of the board, contains a score property, and a mouse region for input.
+The blocks are now created as its children, and its size is used to determining the board size, so as to scale to the available screen size.
+Since it needs to bind its size to a multiple of \c tileSize, \c tileSize needs to be moved into a QML property and out of the script file.
+Note that it can still be accessed from the script.
+
+The mouse region simply calls \c{handleClick()}, which deals with the input events.
+Should those events cause the player to score, \c{gameCanvas.score} is updated.
+The score display text item has also been changed to bind its text property to \c{gamecanvas.score}.
+Note that if score was a global variable in the \c{samegame.js} file you could not bind to it. You can only bind to QML properties.
+
+\c victoryCheck() primarily updates the score variable. But it also pops up a dialog saying \e {Game Over} when the game is over.
+In this example we wanted a pure-QML, animated dialog, and since QML doesn't contain one, we wrote our own.
+Below is the code for the \c Dialog element, note how it's designed so as to be usable imperatively from within the script file (via the functions and signals):
+
+\snippet declarative/tutorials/samegame/samegame3/Dialog.qml 0
+
+And this is how it's used in the main QML file:
+
+\snippet declarative/tutorials/samegame/samegame3/samegame.qml 2
+
+Combined with the line of code in \c victoryCheck, this causes a dialog to appear when the game is over, informing the user of that fact.
+
+We now have a working game! The blocks can be clicked, the player can score, and the game can end (and then you start a new one).
+Below is a screenshot of what has been accomplished so far:
+
+\image declarative-adv-tutorial3.png
+
+Here is the QML code as it is now for the main file:
+
+\snippet declarative/tutorials/samegame/samegame3/samegame.qml 0
+
+And the code for the block:
+
+\snippet declarative/tutorials/samegame/samegame3/Block.qml 0
+
+The game works, but it's a little boring right now. Where are the smooth animated transitions? Where are the high scores?
+If you were a QML expert you could have written these in for the first iteration, but in this tutorial they've been saved
+until the next chapter - where your application becomes alive!

+\page advtutorial4.html
+\title Advanced Tutorial 4 - Finishing Touches
+
+Now we're going to do two things to liven the game up. Animate the blocks and add a web-based high score system.
+
+If you compare the \c samegame3 directory with \c samegame4, you'll noticed that we've cleaned the directory structure up.
+We now have a lot of files, and so they've been split up into folders - the most notable one being a content folder
+which we've placed all the QML but the main file.
+
+\section2 Animated Blocks
+
+The most vital animations are that the blocks move fluidly around the board. QML has many tools for fluid behavior,
+and in this case we're going to use the \l SpringFollow element. By having the script set \c targetX and \c targetY, instead of \c x
+and \c y directly, we can set the \c x and \c y of the block to a follow. \l SpringFollow is a property value source, which means
+that you can set a property to be one of these elements and it will automatically bind the property to the element's value.
+The SpringFollow's value follows another value over time, when the value it is tracking changes the SpringFollow's
+value will also change, but it will move smoothly there over time with a spring-like movement (based on the spring
+parameters specified). This is shown in the below snippet of code from \c Block.qml:
+
+\code
+ property int targetX: 0
+ property int targetY: 0
+
+ x: SpringFollow { source: targetX; spring: 2; damping: 0.2 }
+ y: SpringFollow { source: targetY; spring: 2; damping: 0.2 }
+\endcode
+
+We also have to change the \c{samegame.js} code, so that wherever it was setting the \c x or \c y it now sets \c targetX and \c targetY
+(including when creating the block). This simple change is all you need to get spring moving blocks that no longer teleport
+around the board. If you try doing just this though, you'll notice that they now never jump from one point to another, even in
+the initialization! This gives an odd effect of having them all slide out of the corner (0,0) on start up. We'd rather that they
+fall down from the top in rows. To do this, we disable the \c x follow (but not the \c y follow) and only enable it after we've set
+the \c x in the \c createBlock function. The above snippet now becomes:
+
+\snippet declarative/tutorials/samegame/samegame4/content/BoomBlock.qml 1
+
+The next-most vital animation is a smooth exit. For this animation, we'll use a \l Behavior element. A Behavior is also a property
+value source, and it is much like SpringFollow except that it doesn't model the behavior of a spring. You specify how a Behavior
+transitions using the standard animations. As we want the blocks to smoothly fade in and out we'll set a Behavior on the block
+image's opacity, like so:
+
+\snippet declarative/tutorials/samegame/samegame4/content/BoomBlock.qml 2
+
+Note that the \c{opacity: 0} makes it start out transparent. We could set the opacity in the script file when we create and destroy the blocks,
+but instead we use states (as this is useful for the next animation we'll implement). The below snippet is set on the root
+element of \c{Block.qml}:
+\code
+ property bool dying: false
+ states: [
+ State{ name: "AliveState"; when: spawned == true && dying == false
+ PropertyChanges { target: img; opacity: 1 }
+ }, State{ name: "DeathState"; when: dying == true
+ PropertyChanges { target: img; opacity: 0 }
+ }
+ ]
+\endcode
+
+Now it will automatically fade in, as we set spawned to true already when implementing the block movement animations.
+To fade out, we set 'dying' to true instead of setting opacity to 0 when a block is destroyed (in the \c floodFill function).
+
+The least vital animations are a cool-looking particle effect when they get destroyed. First we create a \l Particles element in
+the block, like so:
+
+\snippet declarative/tutorials/samegame/samegame4/content/BoomBlock.qml 3
+
+To fully understand this you'll want to look at the Particles element documentation, but it's important to note that emissionRate is set
+to zero, so that no particles are emitted normally.
+We next extend the 'dying' state, which creates a burst of particles by calling the burst method on the particles element. The code for the states now look
+like this:
+
+\snippet declarative/tutorials/samegame/samegame4/content/BoomBlock.qml 4
+
+And now the game should be beautifully animated and smooth, with a subtle (or not-so-subtle) animation added for all of the
+player's actions. The end result is shown below, with a different set of images to demonstrate basic themeing:
+
+\image declarative-adv-tutorial4.gif
+
+The basic theme change there is the result of simply replacing the images. This can be done at run time by setting the source property, so a further advanced feature to try on your own is to add a button which toggles between two different themes.
+
+\section2 Offline High Scores
+Another extension we might want for the game is some way of storing and retrieving high scores. This tutorial contains both online and offline high score storage.
+
+For better high score data, we want the name and time of the player. The time is obtained in the script fairly simply, but we
+have to ask the player for their name. We thus re-use the dialog QML file to pop up a dialog asking for the player's name (and
+if they exit this dialog without entering it they have a way to opt out of posting their high score). When the dialog is closed we store the name and high score, using the code below.
+
+\snippet declarative/tutorials/samegame/samegame4/content/samegame.js 2
+
+For offline storage, we use the HTML 5 offline storage JavaScript API to maintain a persistant SQL database unique to this application. This first line in this function calls the function for the web-based high scores, described later, if it has been setup. Next we create an offline storage database for the high scores using openDatabase and prepare the data and SQL query that we want to use to save it. The offline storage API uses SQL queries for data manipulation and retrival, and in the db.transaction call we use three SQL queries to initialize the database (if necessary), and then add to and retrieve high scores. To use the returned data, we turn it into a string with one line per row returned, and show a dialog containing that string. For a more detailed explanation of the offline storage API in QML, consult the global object documentation.
+
+This is one way of storing and displaying high scores locally, but not the only way. A more complex alternative would have been to create a high score dialog component, and pass the results to it for processing and display (instead of resusing the Dialog). This would allow a more themable dialog that could present the high scores better. If your QML is the UI for a C++ application, you could also have passed the score to a C++ function to store it locally in a variety of ways, including a simple format without SQL or in another SQL database.
+
+\section2 Web-based High Scores
+
+You've seen how to store high scores locally, but it is also easy to integrate a web enabled high score storage into your QML application. This tutorial also shows you how to communicate the high scores to a web server. The implementation we've done is very
+simple - the high score data is posted to a php script running on a server somewhere, and that server then stores it and
+displays it to visitors. You could request an XML or QML file from that same server, which contained and displayed the scores,
+but that's beyond the scope of this tutorial. The php script we've used is available in the examples directory.
+
+if the player entered their name we can send the data to the web service in the following snippet out of the script file:
+
+\snippet declarative/tutorials/samegame/samegame4/content/samegame.js 1
+
+This is the same \c XMLHttpRequest() as you'll find in browser JavaScript, and can be used in the same way to dynamically get XML
+or QML from the web service to display the high scores. We don't worry about the response in this case, we just post the high
+score data to the web server. If it had returned a QML file (or a URL to a QML file) you could instantiate it in much the same
+way as you did the blocks.
+
+An alternate way to access and submit web-based data would be to use QML elements designed for this purpose - XmlListModel
+makes it very easy to fetch and display XML based data such as RSS in a QML application (see the Flickr demo for an example).
+
+By following this tutorial you've now ben shown how to write a fully functional application in QML, with the application logic
+written in a script file and with both many fluid animations and being web-enabled. Congratulations, you should now be skilled
+enough to write entire applications in QML.

+\page anchor-layout.html
+\target anchor-layout
+\title Anchor-based Layout in QML
+
+In addition to the more traditional \l Grid, \l Row, and \l Column, QML also provides a way to layout items using the concept of \e anchors. Each item can be thought of as having a set of 6 invisible "anchor lines": \e left, \e horizontalCenter, \e right, \e top, \e verticalCenter, and \e bottom.
+
+\image edges_qml.png
+
+The QML anchoring system allows you to define relationships between the anchor lines of different items. For example, you can write:
+
+\code
+Rectangle { id: rect1; ... }
+Rectangle { id: rect2; anchors.left: rect1.right; ... }
+\endcode
+
+In this case, the left edge of \e rect2 is bound to the right edge of \e rect1, producing the following:
+
+\image edge1.png
+
+The anchoring system also allows you to specify margins and offsets. Margins specify the amount of empty space to leave to the outside of an item, while offsets allow you to manipulate positioning using the center anchor lines. Note that margins specified using the anchor layout system only have meaning for anchors; they won't have any effect when using other layouts or absolute positioning.
+
+\image margins_qml.png
+
+The following example specifies a left margin:
+
+\code
+Rectangle { id: rect1; ... }
+Rectangle { id: rect2; anchors.left: rect1.right; anchors.leftMargin: 5; ... }
+\endcode
+
+In this case, a margin of 5 pixels is reserved to the left of \e rect2, producing the following:
+
+\image edge2.png
+
+You can specify multiple anchors. For example:
+
+\code
+Rectangle { id: rect1; ... }
+Rectangle { id: rect2; anchors.left: rect1.right; anchors.top: rect1.bottom; ... }
+\endcode
+
+\image edge3.png
+
+By specifying multiple horizontal or vertical anchors you can control the size of an item. For example:
+
+\code
+Rectangle { id: rect1; x: 0; ... }
+Rectangle { id: rect2; anchors.left: rect1.right; anchors.right: rect3.left; ... }
+Rectangle { id: rect3; x: 150; ... }
+\endcode
+
+\image edge4.png
+
+\section1 Limitations
+
+For performance reasons, you can only anchor an item to its siblings and direct parent. For example, the following anchor would be considered invalid and would produce a warning:
+
+\badcode
+Item {
+ id: group1
+ Rectangle { id: rect1; ... }
+}
+Item {
+ id: group2
+ Rectangle { id: rect2; anchors.left: rect1.right; ... } // invalid anchor!
+}

+\page qmlanimation.html
+\title QML Animation
+
+Animation in QML is done by animating properties of objects. Properties of type
+real, int, color, rect, point, and size can all be animated.
+
+QML supports three different forms of animation - basic property animation,
+transitions, and property behaviors.
+
+\tableofcontents
+
+\section1 Basic Property Animation
+
+The simplest form of animation is directly using \l PropertyAnimation, which can animate all of the property
+types listed above. If the property you are animating is a number or color, you can alternatively use
+NumberAnimation or ColorAnimation. These elements don't add any additional functionality,
+but will help enforce type correctness and are slightly more efficient.
+
+A property animation can be specified as a value source. This is especially useful for repeating animations.
+
+The following example creates a bouncing effect:
+\qml
+Rectangle {
+ id: rect
+ width: 120; height: 200;
+ Image {
+ id: img
+ source: "qt-logo.png"
+ x: 60-img.width/2
+ y: 0
+ y: SequentialAnimation {
+ running: true
+ repeat: true
+ NumberAnimation { to: 200-img.height; easing: "easeOutBounce"; duration: 2000 }
+ PauseAnimation { duration: 1000 }
+ NumberAnimation { to: 0; easing: "easeOutQuad"; duration: 1000 }
+ }
+ }
+}
+\endqml
+
+\image propanim.gif
+
+When you assign an animation as a value source, you do not need to specify \c property
+or \c target; they are automatically selected for you. You do, however, need to specify \c to, and explicitly
+start the animation (usually via the \c running property).
+
+\qml
+Rectangle {
+ id: rect
+ width: 200; height: 200;
+ Rectangle {
+ color: "red"
+ width: 50; height: 50
+ x: NumberAnimation { to: 50; running: true }
+ }
+}
+\endqml
+
+A property animation can also be specified as a resource that is manipulated from script.
+
+\qml
+PropertyAnimation {
+ id: animation
+ target: image
+ property: "scale"
+ from: 1; to: .5
+}
+Image {
+ id: image
+ source: "image.png"
+ MouseRegion {
+ anchors.fill: parent
+ onPressed: animation.start()
+ }
+}
+\endqml
+
+As can be seen, when an animation is used like this (as opposed to as a value source) you will need
+to explicitly set the \c target and \c property to animate.
+
+Animations can be joined into a group using SequentialAnimation and ParallelAnimation.
+
+\target state-transitions
+\section1 Transitions
+
+QML transitions describe animations to perform when \l{qmlstates}{state} changes occur. A transition
+can only be triggered by a state change.
+
+For example, a transition could describe how an item moves from its initial position to its new position:
+
+\code
+transitions: [
+ Transition {
+ NumberAnimation {
+ matchProperties: "x,y"
+ easing: "easeOutBounce"
+ duration: 200
+ }
+ }
+]
+\endcode
+
+As you can see from the above example, transitions make use of the same basic animation classes introduced
+above. However, you generally use a different set of properties when working with transitions. In the example,
+no \c target or \c property has been specified. Instead, we have specified \c matchProperties,
+which (along with \c matchTargets) acts as a selector to determine which property changes to animate;
+in this case, we will animate any x,y properties that have changed on any objects.
+
+QML transitions also have selectors to determine which state changes a transition should apply to:
+
+\code
+Transition {
+ from: "*"
+ to: "details"
+ ...
+}
+\endcode
+
+Transitions can happen in parallel, in sequence, or in any combination of the two. By default, the top-level
+animations in a transition will happen in parallel. The following example shows a rather complex transition
+making use of both sequential and parallel animations:
+
+\code
+Transition {
+ from: "*"
+ to: "MyState"
+ reversible: true
+ SequentialAnimation {
+ ColorAnimation { duration: 1000 }
+ PauseAnimation { duration: 1000 }
+ ParallelAnimation {
+ NumberAnimation {
+ duration: 1000
+ easing: "easeOutBounce"
+ matchTargets: box1
+ matchProperties: "x,y"
+ }
+ NumberAnimation {
+ duration: 1000
+ matchTargets: box2
+ matchProperties: "x,y"
+ }
+ }
+ }
+}
+\endcode
+
+To insert an explicit animation into your transition, you can use \c target and \c property as normal.
+
+\code
+Transition {
+ from: "*"
+ to: "MyState"
+ reversible: true
+ SequentialAnimation {
+ NumberAnimation {
+ duration: 1000
+ easing: "easeOutBounce"
+ // animate myItem's x and y if they have changed in the state
+ matchTargets: myItem
+ matchProperties: "x,y"
+ }
+ NumberAnimation {
+ duration: 1000
+ // animate myItem2's y to 200, regardless of what happens in the state
+ target: myItem2
+ property: "y"
+ to: 200
+ }
+ }
+}
+\endcode
+
+\section1 Property Behaviors
+
+A \l{Behavior}{property behavior} specifies a default animation to run whenever the property's value changes, regardless
+of what caused the change. Unlike Transition, \l Behavior doesn't provide a way to indicate that a Behavior
+should only apply under certain circumstances.
+
+In the following snippet, we specify that we want the x position of redRect to be animated
+whenever it changes. The animation will last 300 milliseconds and use an InOutQuad easing curve.
+
+\qml
+Rectangle {
+ id: redRect
+ color: "red"
+ width: 100; height: 100
+ x: Behavior { NumberAnimation { duration: 300; easing: "InOutQuad" } }
+}
+\endqml
+
+Like using an animation as a value source, when used in a Behavior and animation does not need to specify
+a \c target or \c property.
+
+To trigger this behavior, we could:
+\list
+\o Enter a state that changes x
+
+\qml
+State {
+ name: "myState"
+ PropertyChanges {
+ target: redRect
+ x: 200
+ ...
+ }
+}
+\endqml
+
+\o Update x from a script
+
+\qml
+MouseRegion {
+ ....
+ onClicked: redRect.x = 24;
+}
+\endqml
+\endlist
+
+If x were bound to another property, triggering the binding would also trigger the behavior.
+
+If a state change has a transition animation matching a property with a Behavior, the transition animation
+will override the Behavior for that state change.

+\page qmldynamicobjects.html
+\title Dynamic Object Creation
+
+QML has some support for dynamically loading and managing QML objects from
+within Javascript blocks. It is preferable to use the existing QML elements for
+dynamic object management wherever possible; these are \l{Loader},
+\l{Repeater}, \l{ListView}, \l{GridView} and \l{PathView}. It is also possible
+to dynamically create and manage objects from C++, and this is preferable for
+hybrid QML/C++ applications - see \l{Using QML in C++ Applications}.
+Dynamically creating and managing objects from
+within Javascript blocks is intended for when none of the existing QML elements
+fit the needs of your application, and you do not desire for your application
+to involve C++ code.
+
+\section1 Creating Objects Dynamically
+There are two ways of creating objects dynamically. You can either create
+a component which instantiates items, or create an item from a string of QML.
+Creating a component is better for the situation where you have a predefined
+item which you want to manage dynamic instances of, and creating an item from
+a string of QML is intended for when the QML itself is generated at runtime.
+
+If you have a component specified in a QML file, you can dynamically load it with
+the createComponent function on the \l{QML Global Object}.
+This function takes the URL of the QML file as its only argument and returns
+a component object which can be used to create and load that QML file.
+
+You can also create a component by placing your QML inside a Component element.
+Referencing that component element by id will be the same as referencing the variable
+which you save the result of createComponent into.
+
+Once you have a component you can use its createObject method to create an instance of
+the component. Example QML script is below. Remember that QML files that might be loaded
+ over the network cannot be expected to be ready immediately.
+ \code
+ var component;
+ var sprite;
+ function finishCreation(){
+ if(component.isReady()){
+ sprite = component.createObject();
+ if(sprite == 0){
+ // Error Handling
+ }else{
+ sprite.parent = page;
+ sprite.x = 200;
+ //...
+ }
+ }else if(component.isError()){
+ // Error Handling
+ }
+ }
+
+ component = createComponent("Sprite.qml");
+ if(component.isReady()){
+ finishCreation();
+ }else{
+ component.statusChanged.connect(finishCreation);
+ }
+ \endcode
+
+ If you are certain the files will be local, you could simplify to
+
+ \code
+ component = createComponent("Sprite.qml");
+ sprite = component.createObject();
+ if(sprite == 0){
+ // Error Handling
+ console.log(component.errorsString());
+ }else{
+ sprite.parent = page;
+ sprite.x = 200;
+ //...
+ }
+ \endcode
+
+After creating the item, remember to set its parent to an item within the scene.
+Otherwise your dynamically created item will not appear in the scene. When using files with relative paths, the path should
+be relative to the file where createComponent is executed.
+
+If the QML does not exist until runtime, you can create a QML item from
+a string of QML using the createQmlObject function, as in the following example:
+
+ \code
+ newObject = createQmlObject('import Qt 4.6; Rectangle {color: "red"; width: 20; height: 20}',
+ targetItem, "dynamicSnippet1");
+ \endcode
+The first argument is the string of QML to create. Just like in a new file, you will need to
+import any types you wish to use. For importing files with relative paths, the path should
+be relative to the file where the item in the second argument is defined. Remember to set the parent after
+creating the item. The second argument is another item in the scene, and the new item is created
+in the same QML Context as this item. The third argument is the file path associated with this
+item, which is used for error reporting.
+
+\section1 Maintaining Dynamically Created Objects
+
+Dynamically created objects may be used the same as other objects, however they
+will not have an id in QML.
+
+A restriction which you need to manage with dynamically created items,
+is that the creation context must outlive the
+created item. The creation context is the QmlContext in which createComponent
+was called, or the context in which the Component element, or the item used as the
+second argument to createQmlObject, was specified. If the creation
+context is destroyed before the dynamic item is, then bindings in the dynamic item will
+fail to work.
+
+\section1 Deleting Objects Dynamically
+You should generally avoid dynamically deleting objects that you did not
+dynamically create. In many UIs, it is sufficient to set the opacity to 0 or
+to move the item off of the edge of the screen. If you have lots of dynamically
+created items however, deleting them when they are no longer used will provide
+a worthwhile performance benefit. Note that you should never manually delete
+items which were dynamically created by QML Elements such as \l{Loader}.
+
+To manually delete a QML item, call its destroy method. This method has one
+argument, which is an approximate delay in ms and which defaults to zero. This
+allows you to wait until the completion of an animation or transition. An example:
+
+\code
+ Component{ id:fadesOut
+ Rectangle{
+ id: rect
+ width: 40; height: 40;
+ opacity: NumberAnimation{from:1; to:0; duration: 1000;}
+ Component.onCompleted: rect.destroy(1000);
+ }
+ }
+ function createFadesOut(parentItem)
+ {
+ var object = fadesOut.createObject();
+ object.parent = parentItem;
+ }
+\endcode
+In the above example, the dynamically created rectangle calls destroy as soon as it's created,
+ but delays long enough for its fade out animation to play.

+\title QML Example - Toggle Switch
+
+This example shows how to create a reusable switch component in QML.
+
+The code for this example can be found in the \c $QTDIR/examples/declarative/slideswitch directory.
+
+\section1 Overview
+
+The elements that composed the switch are:
+
+\list
+\o a \c on property (the interface to interact with the switch),
+\o two images (the background image and the knob),
+\o two mouse regions for user interation (on the background image and on the knob),
+\o two states (a \e on state and a \e off state),
+\o two functions or slots to react to the user interation (\c toggle() and \c dorelease()),
+\o and a transition that describe how to go from one state to the other.
+\endlist
+
+\section1 Switch.qml
+\snippet examples/declarative/slideswitch/content/Switch.qml 0
+
+\section1 Walkthrough
+
+\section2 Interface
+\snippet examples/declarative/slideswitch/content/Switch.qml 1
+
+This property is the interface of the switch. By default, the switch is off and this property is \c false.
+It can be used to activate/disactivate the switch or to query its current state.
+
+In this example:
+
+\qml
+Switch { id: mySwitch; on: true }
+Text { text: "The switch is on"; visible: mySwitch.on == true }
+\endqml
+
+the text will only be visible when the switch is on.
+
+\section2 Images and user interaction
+\snippet examples/declarative/slideswitch/content/Switch.qml 4
+
+First, we create the background image of the switch.
+In order for the switch to toggle when the user clicks on the background, we add a \l{MouseRegion} as a child item of the image.
+A \c MouseRegion has a \c onClicked property that is triggered when the item is clicked. For the moment we will just call a
+\c toggle() function. We will see what this function does in a moment.
+
+\snippet examples/declarative/slideswitch/content/Switch.qml 5
+
+Then, we place the image of the knob on top of the background.
+The interaction here is a little more complex. We want the knob to move with the finger when it is clicked. That is what the \c drag
+property of the \c MouseRegion is for. We also want to toggle the switch if the knob is released between state. We handle this case
+in the \c dorelease() function that is called in the \c onReleased property.
+
+\section2 States
+\snippet examples/declarative/slideswitch/content/Switch.qml 6
+
+We define the two states of the switch:
+\list
+\o In the \e on state the knob is on the right (\c x position is 78) and the \c on property is \c true.
+\o In the \e off state the knob is on the left (\c x position is 1) and the \c on property is \c false.
+\endlist
+
+For more information on states see \l{qmlstates}{QML States}.
+
+\section2 Functions
+
+We add two JavaScript functions to our switch:
+
+\snippet examples/declarative/slideswitch/content/Switch.qml 2
+
+This first function is called when the background image or the knob are clicked. We simply want the switch to toggle between the two
+states (\e on and \e off).
+
+
+\snippet examples/declarative/slideswitch/content/Switch.qml 3
+
+This second function is called when the knob is released and we want to make sure that the knob does not end up between states
+(neither \e on nor \e off). If it is the case call the \c toggle() function otherwise we do nothing.
+
+For more information on scripts see \l{qmlecmascript.html}{JavaScript Blocks}.
+
+\section2 Transition
+\snippet examples/declarative/slideswitch/content/Switch.qml 7
+
+At this point, when the switch toggles between the two states the knob will instantly change its \c x position between 1 and 78.
+In order for the the knob to move smoothly we add a transition that will animate the \c x property with an easing curve for a duration of 200ms.
+
+For more information on transitions see \l{state-transitions}{QML Transitions}.
+
+\section1 Usage
+The switch can be used in a QML file, like this:

+\example declarative/extending/adding
+\title Extending QML - Adding Types Example
+
+The Adding Types Example shows how to add a new element type, \c Person, to QML.
+The \c Person type can be used from QML like this:
+
+\snippet examples/declarative/extending/adding/example.qml 0
+
+\section1 Declare the Person class
+
+All QML elements map to C++ types. Here we declare a basic C++ Person class
+with the two properties we want accessible on the QML type - name and shoeSize.
+Although in this example we use the same name for the C++ class as the QML
+element, the C++ class can be named differently, or appear in a namespace.
+
+\snippet examples/declarative/extending/adding/person.h 0
+
+Following the class declaration, we include the QML_DECLARE_TYPE() macro. This
+is necessary to declare the type to QML. It also includes the logic necessary
+to expose the class to Qt's meta system - that is, it includes the
+Q_DECLARE_METATYPE() functionality.
+
+\section1 Define the Person class
+
+\snippet examples/declarative/extending/adding/person.cpp 0
+
+The Person class implementation is quite basic. The property accessors simply
+return members of the object instance.
+
+The implementation must also include the QML_DEFINE_TYPE() macro. This macro
+registers the Person class with QML as a type in the People library version 1.0,
+and defines the mapping between the C++ and QML class names.
+
+\section1 Running the example
+
+The main.cpp file in the example includes a simple shell application that
+loads and runs the QML snippet shown at the beginning of this page.

+\example declarative/extending/properties
+\title Extending QML - Object and List Property Types Example
+
+This example builds on:
+\list
+\o \l {Extending QML - Adding Types Example}
+\endlist
+
+The Object and List Property Types example shows how to add object and list
+properties in QML. This example adds a BirthdayParty element that specifies
+a birthday party, consisting of a celebrant and a list of guests. People are
+specified using the People QML type built in the previous example.
+
+\snippet examples/declarative/extending/properties/example.qml 0
+
+\section1 Declare the BirthdayParty
+
+The BirthdayParty class is declared like this:
+
+\snippet examples/declarative/extending/properties/birthdayparty.h 0
+\snippet examples/declarative/extending/properties/birthdayparty.h 1
+\snippet examples/declarative/extending/properties/birthdayparty.h 2
+\snippet examples/declarative/extending/properties/birthdayparty.h 3
+
+The class contains a member to store the celebrant object, and also a
+QmlConcreteList<Person *> member.
+
+In QML, the type of a list properties - and the guests property is a list of
+people - are all of type QmlList<T *>*. QmlList is an abstract list interface
+that allows a developer to react to QML accessing and modifying the contents of
+the list. This is useful for implementing "virtual lists" or other advanced
+scenarios, but can't be used directly for the common case of just wanting a
+regular list of things. For this a concrete implementation, QmlConcreteList, is
+provided and that is used here.
+
+\section2 Define the BirthdayParty
+
+The implementation of BirthdayParty property accessors is straight forward.
+

+\title Extending QML - Inheritance and Coercion Example
+
+This example builds on:
+\list
+\o \l {Extending QML - Object and List Property Types Example}
+\o \l {Extending QML - Adding Types Example}
+\endlist
+
+The Inheritance and Coercion Example shows how to use base classes to assign
+elements of more than one type to a property. It specializes the Person element
+developed in the previous examples into two elements - a \c Boy and a \c Girl.
+
+\snippet examples/declarative/extending/coercion/example.qml 0
+
+\section1 Declare Boy and Girl
+
+\snippet examples/declarative/extending/coercion/person.h 0
+
+The Person class remains unaltered in this example and the Boy and Girl C++
+classes are trivial extensions of it. As an example, the inheritance used here
+is a little contrived, but in real applications it is likely that the two
+extensions would add additional properties or modify the Person classes
+behavior.
+
+\section2 Define People as a base class
+
+The implementation of the People class itself has not changed since the the
+previous example. However, as we have repurposed the People class as a common
+base for Boy and Girl, we want to prevent it from being instantiated from QML
+directly - an explicit Boy or Girl should be instantiated instead.
+
+\snippet examples/declarative/extending/coercion/person.cpp 0
+
+While we want to disallow instantiating Person from within QML, it still needs
+to be registered with the QML engine, so that it can be used as a property type
+and other types can be coerced to it. To register a type, without defining a
+named mapping into QML, we use the QML_DEFINE_NOCREATE_TYPE() macro instead of
+the QML_DEFINE_TYPE() macro used previously.
+
+\section2 Define Boy and Girl
+
+The implementation of Boy and Girl are trivial.
+
+\snippet examples/declarative/extending/coercion/person.cpp 1
+
+All that is necessary is to implement the constructor, and to register the types
+and their QML name with the QML engine.
+
+\section1 Running the example
+
+The BirthdayParty element has not changed since the previous example. The
+celebrant and guests property still use the People type.
+
+\snippet examples/declarative/extending/coercion/birthdayparty.h 0
+
+However, as all three types, Person, Boy and Girl, have been registered with the
+QML system, on assignment QML automatically (and type-safely) converts the Boy
+and Girl objects into a Person.

+The main.cpp file in the example includes a simple shell application that

+\page qml-extending.html
+\title Extending QML
+
+The QML syntax declaratively describes how to construct an in memory object
+tree. In Qt, QML is mainly used to describe a visual scene graph, but it is
+not conceptually limited to this: the QML format is an abstract description of
+any object tree. All the QML element types included in Qt are implemented using
+the C++ extension mechanisms describe on this page. Programmers can use these
+APIs to add new types that interact with the existing Qt types, or to repurpose
+QML for their own independent use.
+
+\tableofcontents
+
+\section1 Adding Types
+\target adding-types
+
+\snippet examples/declarative/extending/adding/example.qml 0
+
+The QML snippet shown above instantiates one \c Person instance and sets
+the name and shoeSize properties on it. Everything in QML ultimately comes down
+to either instantiating an object instance, or assigning a property a value.
+QML relies heavily on Qt's meta object system and can only instantiate classes
+that derive from QObject.
+
+The QML engine has no intrinsic knowledge of any class types. Instead the
+programmer must define the C++ types, and their corresponding QML name.
+
+Custom C++ types are made available to QML using these two macros:
+
+\quotation
+\code
+#define QML_DECLARE_TYPE(T)
+#define QML_DEFINE_TYPE(URI,VMAJ,VMIN,QmlName,T)
+\endcode
+
+Register the C++ type \a T with the QML system, and make it available in QML
+under the name \a QmlName in library URI version VMAJ.VMIN.
+\a T and \a QmlName may be the same.
+
+Generally the QML_DECLARE_TYPE() macro should be included immediately following
+the type declaration (usually in its header file), and the QML_DEFINE_TYPE()
+macro in the implementation file. QML_DEFINE_TYPE() must not be present in
+a header file.
+
+Type \a T must be a concrete type that inherits QObject and has a default
+constructor.
+\endquotation
+
+Types can be registered by libraries (such as Qt does), application code,
+or by plugins (see QmlModulePlugin).
+
+Once registered, all of the \l {Qt's Property System}{properties} of a supported
+type are available for use within QML. QML has intrinsic support for properties
+of these types:
+
+\list
+\o bool
+\o unsigned int, int
+\o float, double, qreal
+\o QString
+\o QUrl
+\o QColor
+\o QDate, QTime, QDateTime
+\o QPoint, QPointF
+\o QSize, QSizeF
+\o QRect, QRectF
+\o QVariant
+\endlist
+
+QML is typesafe. Attempting to assign an invalid value to a property will
+generate an error. For example, assuming the name property of the \c Person
+element had a type of QString, this would cause an error:
+
+\code
+Person {
+ // Will NOT work
+ name: 12
+}
+\endcode
+
+\l {Extending QML - Adding Types Example} shows the complete code used to create
+the \c Person type.

+The QML snippet shown above assigns a \c Person object to the \c BirthdayParty's
+celebrant property, and assigns three \c Person objects to the guests property.
+
+QML can set properties of types that are more complex than basic intrinsics like
+integers and strings. Properties can also be object pointers, Qt interface
+pointers, lists of object points, and lists of Qt interface pointers. As QML
+is typesafe it ensures that only valid types are assigned to these properties,
+just like it does for primitive types.
+
+Properties that are pointers to objects or Qt interfaces are declared with the
+Q_PROPERTY() macro, just like other properties. The celebrant property
+declaration looks like this:
+
+\snippet examples/declarative/extending/properties/birthdayparty.h 1
+
+As long as the property type, in this case Person, is registered with QML the
+property can be assigned.
+
+QML also supports assigning Qt interfaces. To assign to a property whose type
+is a Qt interface pointer, the interface must also be registered with QML. As
+they cannot be instantiated directly, registering a Qt interface is different
+from registering a new QML type. The following macros are used instead:
+
+\quotation
+\code
+ #define QML_DECLARE_INTERFACE(T)
+ #define QML_DEFINE_INTERFACE(T)
+\endcode
+
+Register the C++ interface \a T with the QML system.
+
+Generally the QML_DECLARE_INTERFACE() macro should be included immediately
+following the interface declaration (usually in its header file), and the
+QML_DEFINE_INTERFACE() macro in an implementation file. QML_DEFINE_INTERFACE()
+must not be present in a header file.
+
+Following registration, QML can coerce objects that implement this interface
+for assignment to appropriately typed properties.
+\endquotation
+
+The guests property is a list of \c Person objects. Properties that are lists
+of objects or Qt interfaces are also declared with the Q_PROPERTY() macro, just
+like other properties. List properties must have the type \c {QmlList<T *>*}.
+As with object properties, the type \a T must be registered with QML.
+
+The guest property declaration looks like this:
+
+\snippet examples/declarative/extending/properties/birthdayparty.h 2
+
+\l {Extending QML - Object and List Property Types Example} shows the complete
+code used to create the \c BirthdayParty type.
+
+\section1 Inheritance and Coercion
+
+\snippet examples/declarative/extending/coercion/example.qml 0
+
+The QML snippet shown above assigns a \c Boy object to the \c BirthdayParty's
+celebrant property, and assigns three other objects to the guests property.
+
+QML supports C++ inheritance heirarchies and can freely coerce between known,
+valid object types. This enables the creation of common base classes that allow
+the assignment of specialized classes to object or list properties. In the
+snippet shown, both the celebrant and the guests properties retain the Person
+type used in the previous section, but the assignment is valid as both the Boy
+and Girl objects inherit from Person.
+
+To assign to a property, the property's type must have been registered with QML.
+Both the QML_DEFINE_TYPE() and QML_DEFINE_INTERFACE() macros already shown can
+be used to register a type with QML. Additionally, if a type that acts purely
+as a base class that cannot be instantiated from QML needs to be
+registered these macros can be used:
+
+\quotation
+\code
+ #define QML_DECLARE_TYPE(T)
+ #define QML_DEFINE_NOCREATE_TYPE(T)
+\endcode
+
+Register the C++ type \a T with the QML system. QML_DEFINE_NOCREATE_TYPE()
+differs from QML_DEFINE_TYPE() in that it does not define a mapping between the
+C++ class and a QML element name, so the type is not instantiable from QML, but
+it is available for type coercion.
+
+Generally the QML_DECLARE_TYPE() macro should be included immediately following
+the type declaration (usually in its header file), and the
+QML_DEFINE_NOCREATE_TYPE() macro in the implementation file.
+QML_DEFINE_NOCREATE_TYPE() must not be present in a header file.
+
+Type \a T must inherit QObject, but there are no restrictions on whether it is
+concrete or the signature of its constructor.
+\endquotation
+
+QML will automatically coerce C++ types when assigning to either an object
+property, or to a list property. Only if coercion fails does an assignment
+error occur.
+
+\l {Extending QML - Inheritance and Coercion Example} shows the complete
+code used to create the \c Boy and \c Girl types.
+
+\section1 Default Property
+
+\snippet examples/declarative/extending/default/example.qml 0
+
+The QML snippet shown above assigns a collection of objects to the
+\c BirthdayParty's default property.
+
+The default property is a syntactic convenience that allows a type designer to
+specify a single property as the type's default. The default property is
+assigned to whenever no explicit property is specified. As a convenience, it is
+behaviorally identical to assigning the default property explicitly by name.
+
+From C++, type designers mark the default property using a Q_CLASSINFO()
+annotation:
+
+\quotation
+\code
+Q_CLASSINFO("DefaultProperty", "property")
+\endcode
+
+Mark \a property as the class's default property. \a property must be either
+an object property, or a list property.
+
+A default property is optional. A derived class inherits its base class's
+default property, but may override it in its own declaration. \a property can
+refer to a property declared in the class itself, or a property inherited from a
+base class.
+\endquotation
+
+\l {Extending QML - Default Property Example} shows the complete code used to
+specify a default property.
+
+\section1 Grouped Properties
+
+\snippet examples/declarative/extending/grouped/example.qml 1
+
+The QML snippet shown above assigns a number properties to the \c Boy object,
+including four properties using the grouped property syntax.
+
+Grouped properties collect similar properties together into a single named
+block. Grouped properties can be used to present a nicer API to developers, and
+may also simplify the implementation of common property collections across
+different types through implementation reuse.
+
+A grouped property block is implemented as a read-only object property. The
+shoe property shown is declared like this:
+
+\snippet examples/declarative/extending/grouped/person.h 1
+
+The ShoeDescription type declares the properties available to the grouped
+property block - in this case the size, color, brand and price properties.
+
+Grouped property blocks may declared and accessed be recusively.
+
+\l {Extending QML - Grouped Properties Example} shows the complete code used to
+implement the \c shoe property grouping.
+
+\section1 Attached Properties
+
+\snippet examples/declarative/extending/attached/example.qml 1
+
+The QML snippet shown above assigns the rsvp property using the attached
+property syntax.
+
+Attached properties allow unrelated types to annotate other types with some
+additional properties, generally for their own use. Attached properties are
+identified through the use of the attacher type name, in the case shown
+\c BirthdayParty, as a suffix to the property name.
+
+In the example shown, \c BirthdayParty is called the attaching type, and the
+Boy instance the attachee object instance.
+
+For the attaching type, an attached property block is implemented as a new
+QObject derived type, called the attachment object. The properties on the
+attachment object are those that become available for use as the attached
+property block.
+
+Any QML type can become an attaching type by declaring the
+\c qmlAttachedProperties() public function and declaring that the class has
+QML_HAS_ATTACHED_PROPERTIES:
+
+\quotation
+\code
+class MyType : public QObject {
+ Q_OBJECT
+public:
+
+ ...
+
+ static AttachedPropertiesType *qmlAttachedProperties(QObject *object);
+};
+
+QML_DECLARE_TYPEINFO(MyType, QML_HAS_ATTACHED_PROPERTIES)
+QML_DECLARE_TYPE(MyType)
+\endcode
+Return an attachment object, of type \a AttachedPropertiesType, for the
+attachee \a object instance. It is customary, though not strictly required, for
+the attachment object to be parented to \a object to prevent memory leaks.
+
+\a AttachedPropertiesType must be a QObject derived type. The properties on
+this type will be accessible through the attached properties syntax.
+
+This method will be called at most once for each attachee object instance. The
+QML engine will cache the returned instance pointer for subsequent attached
+property accesses. Consequently the attachment object may not be deleted until
+\a object is destroyed.
+\endquotation
+
+Conceptually, attached properties are a \e type exporting a set of additional
+properties that can be set on \e any other object instance. Attached properties
+cannot be limited to only attaching to a sub-set of object instances, although
+their effect may be so limited.
+
+For example, a common usage scenario is for a type to enhance the properties
+available to its children in order to gather instance specific data. Here we
+add a rsvp field to all the guests coming to a birthday party:
+\code
+BirthdayParty {
+ Boy { BirthdayParty.rsvp: "2009-06-01" }
+}
+\endcode
+However, as a type cannot limit the instances to which the attachment object
+must attach, the following is also allowed, even though adding a birthday party
+rsvp in this context will have no effect.
+\code
+GraduationParty {
+ Boy { BirthdayParty.rsvp: "2009-06-01" }
+}
+\endcode
+
+From C++, including the attaching type implementation, the attachment object for
+an instance can be accessed using the following method:
+
+\quotation
+\code
+template<typename T>
+QObject *qmlAttachedPropertiesObject<T>(QObject *attachee, bool create = true);
+\endcode
+Returns the attachment object attached to \a attachee by the attaching type
+\a T. If type \a T is not a valid attaching type, this method always returns 0.
+
+If \a create is true, a valid attachment object will always be returned,
+creating it if it does not already exist. If \a create is false, the attachment
+object will only be returned if it has previously been created.
+\endquotation
+
+\l {Extending QML - Attached Properties Example} shows the complete code used to
+implement the rsvp attached property.
+
+\section1 Signal Support
+
+\snippet examples/declarative/extending/signal/example.qml 0
+\snippet examples/declarative/extending/signal/example.qml 1
+
+The QML snippet shown above associates the evaluation of a JavaScript expression
+with the emission of a Qt signal.
+
+All Qt signals on a registered class become available as special "signal
+properties" within QML to which the user can assign a single JavaScript
+expression. The signal property's name is a transformed version of the Qt
+signal name: "on" is prepended, and the first letter of the signal name upper
+cased. For example, the signal used in the example above has the following
+C++ signature:
+
+\snippet examples/declarative/extending/signal/birthdayparty.h 0
+
+In classes with multiple signals with the same name, only the final signal
+is accessible as a signal property. Although QML provides an element,
+\l Connection, for accessing the other signals it is less elegant. For the best
+QML API, class developers should avoid overloading signal names.
+
+Signal parameters become accessible by name to the assigned script. An
+unnamed parameter cannot be accessed, so care should be taken to name all the
+signal parameters in the C++ class declaration. The intrinsic types
+listed in \l {Adding Types}, as well registered object types are permitted as
+signal parameter types. Using other types is not an error, but the parameter
+value will not be accessible from script.
+
+\l {Extending QML - Signal Support Example} shows the complete code used to
+implement the onPartyStarted signal property.
+
+\section1 Property Value Sources
+
+\snippet examples/declarative/extending/valuesource/example.qml 0
+\snippet examples/declarative/extending/valuesource/example.qml 1
+
+The QML snippet shown above assigns a property value to the speaker property.
+A property value source generates a value for a property that changes over time.
+
+Property value sources are most commonly used to do animation. Rather than
+constructing an animation object and manually setting the animation's "target"
+property, a property value source can be assigned directly to a property of any
+type and automatically set up this association.
+
+The example shown here is rather contrived: the speaker property of the
+BirthdayParty object is a string that is printed every time it is assigned and
+the HappyBirthday value source generates the lyrics of the song
+"Happy Birthday".
+
+\snippet examples/declarative/extending/valuesource/birthdayparty.h 0
+
+Normally, assigning an object to a string property would not be allowed. In
+the case of a property value source, rather than assigning the object instance
+itself, the QML engine sets up an association between the value source and
+the property.
+
+Property value sources are special types that derive from the
+QmlPropertyValueSource base class. This base class contains a single method,
+QmlPropertyValueSource::setTarget(), that the QML engine invokes when
+associating the property value source with a property. The relevant part of
+the HappyBirthday type declaration looks like this:
+
+\snippet examples/declarative/extending/valuesource/happybirthday.h 0
+\snippet examples/declarative/extending/valuesource/happybirthday.h 1
+\snippet examples/declarative/extending/valuesource/happybirthday.h 2
+
+In all other respects, property value sources are regular QML types. They must
+be registered with the QML engine using the same macros as other types, and can
+contain properties, signals and methods just like other types.
+
+When a property value source object is assigned to a property, QML first tries
+to assign it normally, as though it were a regular QML type. Only if this
+assignment fails does the engine call the setTarget() method. This allows
+the type to also be used in contexts other than just as a value source.
+
+\l {Extending QML - Property Value Source Example} shows the complete code used
+implement the HappyBirthday property value source.
+
+\section1 Property Binding
+
+\snippet examples/declarative/extending/binding/example.qml 0
+\snippet examples/declarative/extending/binding/example.qml 1
+
+The QML snippet shown above uses a property binding to ensure the
+HappyBirthday's name property remains up to date with the celebrant.
+
+Property binding is a core feature of QML. In addition to assigning literal
+values, property bindings allow the developer to assign an arbitrarily complex
+JavaScript expression that may include dependencies on other property values.
+Whenever the expression's result changes - through a change in one of its
+constituent values - the expression is automatically reevaluated and
+the new result assigned to the property.
+
+All properties on custom types automatically support property binding. However,
+for binding to work correctly, QML must be able to reliably determine when a
+property has changed so that it knows to reevaluate any bindings that depend on
+the property's value. QML relies on the presence of a
+\c {Qt's Property System}{NOTIFY signal} for this determination.
+
+Here is the celebrant property declaration:
+
+\snippet examples/declarative/extending/binding/birthdayparty.h 0
+
+The NOTIFY attribute is followed by a signal name. It is the responsibility of
+the class implementer to ensure that whenever the property's value changes, the
+NOTIFY signal is emitted. The signature of the NOTIFY signal is not important to QML.
+
+To prevent loops or excessive evaluation, developers should ensure that the
+signal is only emitted whenever the property's value is actually changed. If
+a property, or group of properties, is infrequently used it is permitted to use
+the same NOTIFY signal for several properties. This should be done with care to
+ensure that performance doesn't suffer.
+
+To keep QML reliable, if a property does not have a NOTIFY signal, it cannot be
+used in a binding expression. However, the property can still be assigned
+a binding as QML does not need to monitor the property for change in that
+scenario.
+
+Consider a custom type, \c TestElement, that has two properties, "a" and "b".
+Property "a" does not have a NOTIFY signal, and property "b" does have a NOTIFY
+signal.
+
+\code
+TestElement {
+ // This is OK
+ a: b
+}
+TestElement {
+ // Will NOT work
+ b: a
+}
+\endcode
+
+The presence of a NOTIFY signal does incur a small overhead. There are cases
+where a property's value is set at object construction time, and does not
+subsequently change. The most common case of this is when a type uses
+\l {Grouped Properties}, and the grouped property object is allocated once, and
+only freed when the object is deleted. In these cases, the CONSTANT attribute
+may be added to the property declaration instead of a NOTIFY signal.
+
+\snippet examples/declarative/extending/binding/person.h 0
+
+Extreme care must be taken here or applications using your type may misbehave.
+The CONSTANT attribute should only be used for properties whose value is set,
+and finalized, only in the class constructor. All other properties that want
+to be used in bindings should have a NOTIFY signal instead.
+
+\l {Extending QML - Binding Example} shows the BirthdayParty example updated to
+include NOTIFY signals for use in binding.
+
+\section1 Binding and Script Properties
+
+While generally no changes are needed to a C++ class to use property
+binding, sometimes more advanced interaction between the binding engine and
+an object is desirable. To facilitate this, there is a special exception
+in the bind engine for allowing an object to access the binding directly.
+
+If a binding is assigned to a property with a type of QmlBinding
+pointer (ie. \c {QmlBinding *}), each time the binding value changes,
+a QmlBinding instance is assigned to that property. The QmlBinding instance
+allows the object to read the binding and to evaluate the binding's current value.
+
+\section1 Extension Objects
+
+\snippet examples/declarative/extending/extended/example.qml 0
+
+The QML snippet shown above adds a new property to an existing C++ type without
+modifying its source code.
+
+When integrating existing classes and technology into QML, their APIs will often
+need to be tweaked to fit better into the declarative environment. Although
+the best results are usually obtained by modifying the original classes
+directly, if this is either not possible or is complicated by some other
+concerns, extension objects allow limited extension possibilities without
+direct modifications.
+
+Extension objects are used to add additional properties to an existing type.
+Extension objects can only add properties, not signals or methods. An extended
+type definition allows the programmer to supply an additional type - known as the
+extension type - when registering the target class whose properties are
+transparently merged with the original target class when used from within QML.
+
+An extension class is a regular QObject, with a constructor that takes a QObject
+pointer. When needed (extension classes are delay created until the first extended
+property is accessed) the extension class is created and the target object is
+passed in as the parent. When an extended property on the original is accessed,
+the appropriate property on the extension object is used instead.
+
+When an extended type is installed, one of the
+\code
+ #define QML_DEFINE_EXTENDED_TYPE(URI, VMAJ, VFROM, VTO, QmlName,T, ExtendedT)
+ #define QML_DEFINE_EXTENDED_NOCREATE_TYPE(T, ExtendedT)
+\endcode
+macros should be used instead of the regular \c QML_DEFINE_TYPE or
+\c QML_DEFINE_NOCREATE_TYPE. The arguments are identical to the corresponding
+non-extension object macro, except for the ExtendedT parameter which is the type
+of the extension object.
+
+\section1 Optimization
+
+Often to develop high performance elements it is helpful to know more about the
+status of the QML engine. For example, it might be beneficial to delay
+initializing some costly data structures until after all the properties have been
+set.
+
+The QML engine defines an interface class called QmlParserStatus, which contains a
+number of virtual methods that are invoked at various stages during component
+instantiation. To receive these notifications, an element implementation inherits
+QmlParserStatus and notifies the Qt meta system using the Q_INTERFACES() macro.
+
+For example,
+
+\code
+class Example : public QObject, public QmlParserStatus
+{
+ Q_OBJECT
+ Q_INTERFACES(QmlParserStatus)
+public:
+ virtual void componentComplete()
+ {
+ qDebug() << "Woohoo! Now to do my costly initialization";
+ }
+};
+\endcode

+\title Extending types from QML
+
+Many of the elements available for use in QML are implemented in
+\l {Extending QML}{C++}. These types are know as "core types". QML
+allows programmers to build new, fully functional elements without using C++.
+Existing core types can be extended, and new types defined entirely in the QML
+language.
+
+\tableofcontents
+
+\section1 Adding new properties
+
+New properties can be added to an existing type. These new properties are
+available for use within QML, and also appear as regular Qt properties on the
+C++ object, accessible through the regular property access mechanisms.
+
+Like all properties in QML, custom properties are typed. The type is used to
+define the property's behavior, and also determines the C++ type of the created
+Qt property. The following table shows the list of types available when
+declaring a new property, and the corresponding C++ type.
+
+\table
+\header \o QML Type Name \o C++ Type Name
+\row \o int \o int
+\row \o bool \o bool
+\row \o double \o double
+\row \o real \o double
+\row \o string \o QString
+\row \o url \o QUrl
+\row \o color \o QColor
+\row \o date \o QDate
+\row \o var \o QVariant
+\row \o variant \o QVariant
+\endtable
+
+QML supports two methods for adding a new property to a type: a new property
+definition, and a property alias.
+
+\section2 Property definitions
+
+Property definitions add a new property to an existing type. The storage of the
+property is managed by QML. The defined property may be read, written and bound
+to and from.
+
+The syntax for defining a new property is:
+\code
+ [default] property <type> <name>[: defaultValue]
+\endcode
+
+This declaration may appear anywhere within a type body, but it is customary to
+include it at the top. Attempting to declare two properties with the same name
+in the same type block is an error. However, a new property may reuse the name
+of an existing property on the type. This should be done with caution, as the
+existing property will be hidden, and become inaccessible.
+
+The <type> must be one of the QML type names shown in the above table.
+Additionally, an optional default value of the property can be provided. The
+default value is a convenient shortcut, but is behaviorally identical to doing
+it in two steps, like this:
+
+\code
+ // Use default value
+ property int myProperty: 10
+
+ // Longer, but behaviorally identical
+ property int myProperty
+ myProperty: 10
+\endcode
+
+If specified, the optional "default" attribute marks the new property as the
+types default property, overriding any existing default property. Using the
+default attribute twice in the same type block is an error.
+
+The following example shows how to declare a new "innerColor" property that
+controls the color of the inner rectangle.
+
+\code
+ Rectangle {
+ property color innerColor: "black"
+
+ color: "red"; width: 100; height: 100
+ Rectangle {
+ anchors.centerIn: parent
+ width: parent.width - 10
+ height: parent.height - 10
+ color: innerColor
+ }
+ }
+\endcode
+
+\target qml-property-aliases
+\section2 Property aliases
+
+Property aliases are a more advanced form of property declaration. Unlike a
+property definition, that allocates a new, unique storage space for the
+property, a property alias connects the newly declared property (called the
+aliasing property) to an existing property (the aliased property). Read
+operations on the aliasing property act as read operations on the aliased
+property, and write operations on the aliasing property as write operations on
+the aliased property.
+
+A property alias declaration looks a lot like a property definition:
+\code
+ [default] property alias <name>: <alias reference>
+\endcode
+
+As the aliasing property has the same type as the aliased property, an explicit
+type is omitted, and the special "alias" keyword is used. Instead of a default
+value, a property alias includes a compulsary alias reference. The alias
+reference is used to locate the aliased property. While similar to a property
+binding, the alias reference syntax is highly restricted.
+
+An alias reference takes one of the following forms
+\code
+ <id>.<property>
+ <id>
+\endcode
+
+where <id> must refer to an object id within the same component as the type
+declaring the alias, and, optionally, <property> refers to a property on that object.
+
+Here is the property definition example rewritten to use property aliases.
+\code
+Rectangle {
+ property alias innerColor: innerRect.color
+
+ color: "red"; width: 100; height: 100
+ Rectangle {
+ id: innerRect
+ anchors.centerIn: parent
+ width: parent.width - 10
+ height: parent.height - 10
+ color: "black"
+ }
+}
+\endcode
+
+Aliases are most useful when \l {Defining new Components}. Consequently
+they have several apparent limitations that only make sense in this context.
+
+Aliases are only activated once the component specifying them is completed. The
+most obvious consequence of this is that the component itself cannot generally
+use the aliased property directly. For example, this will not work:
+
+\code
+ // Does NOT work
+ property alias innerColor: innerRect.color
+ innerColor: "black"
+\endcode
+
+This behavior is required to allow type developers to redefine the behavior
+of existing property names while continuing to use the existing behavior within
+the type they are building, something that is not possible with property
+definitions. In the example used so far, this could allows the developer to fix
+the external rectangle's color as "red" and redefine the "color" property to
+refer to the inner rectangle, like this:
+
+\code
+Rectangle {
+ property alias color: innerRect.color
+
+ color: "red"; width: 100; height: 100
+ Rectangle {
+ id: innerRect
+ anchors.centerIn: parent
+ width: parent.width - 10
+ height: parent.height - 10
+ color: "black"
+ }
+}
+\endcode
+
+Users of this type would not be able to affect the color of the red rectangle,
+but would find using the "color" property, rather than the strange new
+"innerColor" property, much more familiar.
+
+A second, much less significant, consequence of the delayed activation of
+aliases is that an alias reference cannot refer to another aliasing property
+declared within the same component. This will not work:
+
+\code
+ // Does NOT work
+ id: root
+ property alias innerColor: innerRect.color
+ property alias innerColor2: root.innerColor
+\endcode
+
+From outside the component, aliasing properties appear as regular Qt properties
+and consequently can be used in alias references.
+
+\section1 Adding new signals
+
+New signals can be added to an existing type. These new signals are available
+for use within QML, and also appear as regular Qt signals on the C++ object that
+can be used in Qt signal/slot connections.
+
+The syntax for defining a new signal is:
+\code
+signal <name>[([<type> <parameter name>[, ...]])]
+\endcode
+
+This declaration may appear anywhere within a type body, but it is customary to
+include it at the top. Attempting to declare two signals or methods with the
+same name in the same type block is an error. However, a new signal may reuse
+the name of an existing signal on the type. This should be done with caution,
+as the existing signal may be hidden and become inaccessible.
+
+The options for parameter types are the same as for property types (see
+\l {Adding new properties}. If this signal has no parameters, the parameter
+list may be omitted entirely.
+
+Here are three examples of signal declarations:
+\code
+ Item {
+ signal clicked
+ signal hovered()
+ signal performAction(string action, var actionArgument)
+ }
+\endcode
+
+Adding a signal to an item automatically adds a signal handler to it.
+The signal hander is named on<Signal name>, with the first letter of the
+signal name being upper cased. The above example item would now have the
+following signal handlers:
+
+\list
+ \o onClicked
+ \o onHovered
+ \o onPerformAction
+\endlist
+
+\section1 Adding new methods
+
+New methods can be added to an existing type. These new methods are available
+for use within QML, and also appear as regular Qt slots on the C++ object that
+can be used in Qt signal/slot connections.
+
+\code
+function <name>([<parameter name>[, ...]]) { <body> }
+\endcode
+
+This declaration may appear anywhere within a type body, but it is customary to
+include it at the top. Attempting to declare two methods or signals with the
+same name in the same type block is an error. However, a new method may reuse
+the name of an existing method on the type. This should be done with caution,
+as the existing method may be hidden and become inaccessible.
+
+Methods parameters are not typed. In C++ these parameters are of type QVariant.
+The body of the method is written in JavaScript and may access the parameters by
+name.
+
+This example adds a new method that behaves like a child:
+\code
+Item {
+ function say(text) {
+ console.log("You said " + text);
+ }
+}
+\endcode
+
+\section1 Defining new Components
+\target components
+
+A component is a reusable type with a well-defined interface built entirely in
+QML. Components appear as regular QML elements, and can be used interchangably
+with core types. Components allow developers to create new types to be reused
+in other projects without the use of C++. Components can also help to reduce
+duplication inside one project by limiting the need for large numbers of
+copy-and-pasted blocks.
+
+Any snippet of QML code can become a component, just by placing it in the file
+"<Name>.qml" where <Name> is the new element name, and begins with an uppercase
+letter. These QML files automatically become available as new QML element types
+to other QML components and applications in the same directory.
+
+For example, here we show how a component named "Box" is defined and used
+multiple times by an application.
+
+\table
+\row
+\o application.qml
+\code
+Rectangle {
+ width: 100; height: 400;
+ Box { x: 0; y: 0 }
+ Box { x: 0; y: 150 }
+ Box { x: 0; y: 300 }
+}
+\endcode
+\o Box.qml
+\code
+Rectangle {
+ width: 100; height: 100;
+ color: "blue"
+}
+\endcode
+\endtable
+
+Components may be collected into \l {Modules} that gives the
+developer more freedom than just putting files in the same directory.
+
+\section2 Building reusable components
+
+A component type built to be reused by others must have a well defined
+interface. In QML, an interface consists of a defined collection of
+properties, signals and methods. Users of a component have access to all the
+properties, signals and methods defined on the root element of the component.
+
+In the component example above, the root element of the "Box" component is a
+Rect. As the Rect type has a "color" property, this property is accessible to
+users of the Box component. For example, the application.qml can be modified
+to show three different colored boxes like this:
+\code
+Rectangle {
+ width: 100; height: 400;
+ Box { x: 0; y: 0; color: "red"; }
+ Box { x: 0; y: 150; color: "yellow"; }
+ Box { x: 0; y: 300; color: "green"; }
+}
+\endcode
+
+As expected, adding additional properties to the root element of Box, makes them
+available externally. Here we add a "text" property:
+
+\table
+\row
+\o application.qml
+\code
+Rectangle {
+ width: 100; height: 400;
+ Box { x: 0; y: 0; color: "red"; text: "stop" }
+ Box { x: 0; y: 150; color: "yellow"; text: "slow" }
+ Box { x: 0; y: 300; color: "green"; text: "go" }
+}
+\endcode
+\o Box.qml
+\code
+Rectangle {
+ property alias text: myText.text
+ width: 100; height: 100;
+ color: "blue"
+ Text {
+ id: myText
+ anchors.centerIn: parent
+ }
+}
+\endcode
+\endtable
+
+Methods and signals may be added in the same way.
+
+As all external methods, signals and properties are accessible to external
+users, developers should ensure that setting these properties does not have
+any undesirable side-effects. For most resiliance, root level properties should
+only be used for literal default values. When a root level property must be
+used inside the component - such as the children property - property aliases
+can be used to redirect this property to a "safe" location for external users.
+Try to think of the root level properties as being "owned" by the components
+user, rather than the component itself.

+\page qmlfocus.html
+\title Keyboard Focus in QML
+
+When a key is pressed or released, a key event is generated and delivered to the
+focused QML \l Item. To facilitate the construction of reusable components
+and to address some of the cases unique to fluid user interfaces, the QML items add a
+\e scope based extension to Qt's traditional keyboard focus model.
+
+\tableofcontents
+
+\section1 Key Handling Overview
+
+When the user presses or releases a key, the following occurs:
+\list 1
+\o Qt receives the key action and generates a key event.
+\o If the Qt widget containing the \l QmlView has focus, the key event is delivered to it. Otherwise, regular Qt key handling continues.
+\o The key event is delivered by the scene to the QML \l Item with \e {active focus}. If no \l Item has \e {active focus}, the key event is \l {QEvent::ignore()}{ignored} and regular Qt key handling continues.
+\o If the QML \l Item with \e {active focus} accepts the key event, propagation stops. Otherwise the event is "bubbled up", by recursively passing it to each \l Item's parent until either the event is accepted, or the root \l Item is reached.
+
+If the \c {Rectangle} element in the following example has active focus and the \e A key is pressed,
+it will bubble up to its parent. However, pressing the \e B key will bubble up to the root
+item and thus subsequently be \l {QEvent::ignore()}{ignored}.
+
+\code
+Item {
+ Item {
+ Keys.onPressed: if (event.key == Qt.Key_A) { console.log('Key A was pressed'); event.accepted = true }
+ Rectangle {}
+ }
+}
+\endcode
+
+\o If the root \l Item is reached, the key event is \l {QEvent::ignore()}{ignored} and regular Qt key handling continues.
+
+\endlist
+
+See also the \l {Keys}{Keys attached property} and \l {KeyNavigation}{KeyNavigation attached property}.
+
+\section1 Querying the Active Focus Item
+
+Whether or not an \l Item has \e {active focus} can be queried through the
+property \c {Item::focus}. For example, here we have a \l Text
+element whose text is determined by whether or not it has \e {active focus}.
+
+\code
+Text {
+ text: focus ? "I have active focus!" : "I do not have active focus"
+}
+\endcode
+
+\section1 Acquiring Focus and Focus Scopes
+
+An \l Item requests focus by setting the \c {Item::focus} property to true.
+
+For very simple cases simply setting the \c {Item::focus} property is sometimes
+sufficient. If we run the following example in the \c qmlviewer, we see that
+the \c {keyHandler} element has \e {active focus} and pressing the 'A', 'B'
+or 'C' keys modifies the text appropriately.
+
+\table
+\row
+\o \code
+ Rectangle {
+ color: "lightsteelblue"; width: 240; height: 25
+ Text { id: myText }
+ Item {
+ id: keyHandler
+ focus: true
+ Keys.onPressed: {
+ if (event.key == Qt.Key_A)
+ myText.text = 'Key A was pressed'
+ else if (event.key == Qt.Key_B)
+ myText.text = 'Key B was pressed'
+ else if (event.key == Qt.Key_C)
+ myText.text = 'Key C was pressed'
+ }
+ }
+ }
+\endcode
+\o \image declarative-qmlfocus1.png
+\endtable
+
+However, were the above example to be used as a self-contained component, this
+simple use of the \c {Item::focus} property is no longer sufficient. The left
+hand side of the following table shows what we would like to be able to write.
+Here we create two instances of our previously defined component, and set the
+second one to have focus. The intention is that when the \e A, \e B, or \e C
+keys are pressed, the second of the two components receives the event and
+reponds accordingly.
+
+\table
+\row
+\o \code
+Rectangle {
+ color: "red"; width: 240; height: 55
+ MyWidget {}
+ MyWidget { y: 30; focus: true }
+}
+\endcode
+\o \code
+Rectangle {
+ color: "red"; width: 240; height: 55
+ Rectangle {
+ color: "lightsteelblue"; width: 240; height: 25
+ Text { id: myText }
+ Item {
+ id: keyHandler
+ focus: true
+ Keys.onPressed: {
+ if (event.key == Qt.Key_A)
+ myText.text = 'Key A was pressed'
+ else if (event.key == Qt.Key_B)
+ myText.text = 'Key B was pressed'
+ else if (event.key == Qt.Key_C)
+ myText.text = 'Key C was pressed'
+ }
+ }
+ }
+ Rectangle {
+ y: 30; focus: true
+ color: "lightsteelblue"; width: 240; height: 25
+ Text { id: myText }
+ Item {
+ id: keyHandler
+ focus: true
+ Keys.onPressed: {
+ if (event.key == Qt.Key_A)
+ myText.text = 'Key A was pressed'
+ else if (event.key == Qt.Key_B)
+ myText.text = 'Key B was pressed'
+ else if (event.key == Qt.Key_C)
+ myText.text = 'Key C was pressed'
+ }
+ }
+ }
+}
+\endcode
+\endtable
+
+The right hand side of the example shows the expanded code - the equivalent QML
+without the use of the component \c {MyWidget}. From this, the problem is
+evident - there are no less than three elements that have the \c {Item::focus}
+property set to true. Ultimately only one element can have focus, and the
+system has to decide which on. In this case the first appearance of the
+\c {Item::focus} property being set to true on line 4 is selected, and the value
+of \c {Item::focus} in the other two instances is reverted back to false. This
+is exactly the opposite of what was wanted!
+
+This problem is fundamentally one of visibility. The \c {MyWidget}
+components each set their \c {keyHandler} Items as focused as that is all they can
+do - they don't know how they are going to be used, but they do know that when
+they're in use their \c {keyHandler} element is what needs focus. Likewise
+the code that uses the two \c {MyWidgets} sets the second \c {MyWidget} as
+focused. While it doesn't know exactly how the \c {MyWidget} is
+implemented, it knows that it wants the second one to be focused. This allows us
+to achieve encapsulation, allowing each widget to focus on it's appropriate behaviour
+itself.
+
+To solve this problem - allowing components to care about what they know about
+and ignore everything else - the QML items introduce a concept known as a
+\e {focus scope}. For existing Qt users, a \e {focus scope} is like an
+automatic focus proxy. A \e {focus scope} is created using the \l FocusScope
+element.
+
+In the next example, a \l FocusScope is added to the component, and the visual
+result shown.
+
+\table
+\row
+\o \code
+FocusScope {
+ width: 240; height: 25
+ Rectangle {
+ color: "lightsteelblue"; width: 240; height: 25
+ Text { id: myText }
+ Item {
+ id: keyHandler
+ focus: true
+ Keys.onPressed: {
+ if (event.key == Qt.Key_A)
+ myText.text = 'Key A was pressed'
+ else if (event.key == Qt.Key_B)
+ myText.text = 'Key B was pressed'
+ else if (event.key == Qt.Key_C)
+ myText.text = 'Key C was pressed'
+ }
+ }
+ }
+}
+\endcode
+\o \image declarative-qmlfocus2.png
+\endtable
+
+Conceptually \e {focus scopes} are quite simple.
+\list
+\o Within each \e {focus scope} one element may have \c {Item::focus} set to true.
+If more than one \l Item has the \c {Item::focus} property set, the first is selected
+and the others are unset, just like when there are no \e {focus scopes}.
+\o When a \e {focus scope} receives \e {active focus}, the contained element with
+\c {Item::focus} set (if any) also gets \e {active focus}. If this element is
+also a \l FocusScope, the proxying behaviour continues. Both the
+\e {focus scope} and the sub-focused item will have \c {Item::focus} set.
+\endlist
+
+So far the example has the second component statically selected. It is trivial
+now to extend this component to make it clickable, and add it to the original
+application. We still set a one of the widgets as focused by default, but from
+then on clicking the either one gives it focus.
+
+\table
+\row
+\o \code
+Rectangle {
+ color: "red"; width: 240; height: 55
+ MyClickableWidget {}
+ MyClickableWidget { y: 30; focus: true }
+}
+\endcode
+\o \code
+FocusScope {
+ id: page; width: 240; height: 25
+ MyWidget { focus: true }
+ MouseRegion { anchors.fill: parent; onClicked: { page.focus = true } }
+}
+\endcode
+\endtable
+
+\image declarative-qmlfocus3.png
+
+When a QML item explicitly relinquishes focus (by setting its
+\c {Item::focus} property to false while it has \e {active focus}), the system
+does not automatically select another element to receive focus. That is, it
+is possible for there to be no currently \e {active focus}.
+
+\section1 Advanced uses of Focus Scopes
+
+Focus scopes allow focus to allocation to be easily partitioned. Several
+QML items use it to this effect.
+
+\l ListView, for example, is itself a focus scope. Generally this isn't
+noticable as \l ListView doesn't usually have manually added visual children.
+By being a focus scope, \l ListView can focus the current list item without
+worrying about how that will effect the rest of the application. This allows
+the current item delegate to react to key presses.
+
+This contrived example shows how this works. Pressing the \c Return key will
+print the name of the current list item.
+
+\table
+\row
+\o \code
+Rectangle {
+ color: "lightsteelblue"; width: 240; height: 320
+
+ ListView {
+ id: myView; anchors.fill: parent; focus: true
+ model: ListModel {
+ ListElement { name: "Bob" }
+ ListElement { name: "John" }
+ ListElement { name: "Michael" }
+ }
+ delegate: FocusScope {
+ width: contents.width; height: contents.height
+ Text {
+ focus: true
+ text: name
+ Keys.onReturnPressed: console.log(name)
+ }
+ }
+ }
+}
+\endcode
+\o \image declarative-qmlfocus4.png
+\endtable
+
+While the example is simple, there's a lot going on behind the scenes. Whenever
+the current item changes, the \l ListView sets the delegate's \c {Item::focus}
+property. As the \l ListView is a \e {focus scope}, this doesn't effect the
+rest of the application. However, if the \l ListView itself has
+\e {active focus} this causes the delegate itself to receive \e {active focus}.
+In this example, the root element of the delegate is also a \e {focus scope},
+which in turn gives \e {active focus} to the \c {Text} element that
+actually performs the work of handling the \e {Return} key.
+
+All of the QML view classes, such as \l PathView and \l GridView, behave
+in a similar mannor to allow key handling in their respective delegates.
+
+\section1 Focus Panels
+
+Traditional UIs are composed of many top-level windows. Windows actually
+perform two tasks - they act as the visual bounds for a widget, and they segment
+focus. Each window has a separate focused widget, that becomes (to mix
+terminologies) the \e {active focus} widget when the window is the active
+window.
+
+### Focus panels do basically the same thing.

+\title QML Global Object
+
+Contains all the properties of the JavaScript global object, plus:
+
+\tableofcontents
+
+\section1 Qt Object
+
+The Qt object provides useful enums and functions from Qt, for use in all QML
+files.
+
+\section2 Enums
+The Qt object contains all enums in the Qt namespace. For example, you can
+access the AlignLeft member of the Qt::AlignmentFlag enum with \c Qt.AlignLeft.
+
+For a full list of enums, see the \l{Qt Namespace} documentation.
+
+\section2 Types
+The Qt object also contains helper functions for creating objects of specific
+data types. This is primarily useful when setting the properties of an item
+when the property has one of the following types:
+
+\list
+\o Color
+\o Rect
+\o Point
+\o Size
+\o Vector3D
+\endlist
+
+There are also string based constructors for these types, see \l{basicqmltypes.html}{Qml Types}.
+
+\section3 Qt.rgba(qreal red, qreal green, qreal blue, qreal alpha)
+This function returns a Color with the specified \c red, \c green, \c blue and \c alpha components. All components should be in the range 0-1 inclusive.
+
+\section3 Qt.hsla(qreal hue, qreal saturation, qreal lightness, qreal alpha)
+This function returns a Color with the specified \c hue, \c saturation, \c lightness and \c alpha components. All components should be in the range 0-1 inclusive.
+
+\section3 Qt.rect(int x, int y, int width, int height)
+This function returns a Rect with the top-left corner at \c x, \c y and the specified \c width and \c height.
+\section3 Qt.point(int x, int y)
+This function returns a Point with the specified \c x and \c y coordinates.
+\section3 Qt.size(int width, int height)
+This function returns as Size with the specified \c width and \c height.
+\section3 Qt.vector3d(real x, real y, real z)
+This function returns a Vector3D with the specified \c x, \c y and \c z.
+\section2 Functions
+The Qt object also contains the following miscellaneous functions which expose Qt functionality for use in QML.
+
+\section3 Qt.lighter(color baseColor)
+This function returns a color 50% lighter than \c baseColor. See QColor::lighter() for further details.
+\section3 Qt.darker(color baseColor)
+This function returns a color 50% darker than \c baseColor. See QColor::darker() for further details.
+\section3 Qt.tint(color baseColor, color tintColor)
+ This function allows tinting one color with another.
+
+ The tint color should usually be mostly transparent, or you will not be able to see the underlying color. The below example provides a slight red tint by having the tint color be pure red which is only 1/16th opaque.
+
+ \qml
+ Rectangle { x: 0; width: 80; height: 80; color: "lightsteelblue" }
+ Rectangle { x: 100; width: 80; height: 80; color: Qt.tint("lightsteelblue", "#10FF0000") }
+ \endqml
+ \image declarative-rect_tint.png
+
+ Tint is most useful when a subtle change is intended to be conveyed due to some event; you can then use tinting to more effectively tune the visible color.
+\section3 Qt.closestAngle(number fromAngle, number toAngle)
+This function returns an equivalent angle to toAngle, such that the difference between fromAngle and toAngle is never more than 180 degrees. This is useful when animating angles using a NumberAnimation, which does not know about equivalent angles, when you always want to take the shortest path.
+
+For example, the following would rotate myItem counterclockwise from 350 degrees to 10 degrees, for a total of 340 degrees of rotation.
+\qml
+NumberAnimation { target: myItem; property: "rotation"; from: 350; to: 10 }
+\endqml
+
+while the following would rotate myItem clockwise from 350 degrees to 370 degrees (which is visually equivilant to 10 degrees), for a total of 20 degrees of rotation.
+\qml
+NumberAnimation { target: myItem; property: "rotation"; from: 350; to: Qt.closetAngle(350, 10) }
+\endqml
+
+\section3 Qt.playSound(url soundLocation)
+This function plays the audio file located at \c soundLocation. Only .wav files are supported.
+
+\section3 Qt.openUrlExternally(url target)
+This function attempts to open the specified \c target url in an external application, based on the user's desktop preferences. It will return true if it succeeds, and false otherwise.
+
+\section3 Qt.md5(data)
+This function returns a hex string of the md5 hash of \c data.
+
+\section1 Dynamic Object Creation
+The following functions on the global object allow you to dynamically create QML
+items from files or strings. See \l{Dynamic Object Management} for an overview
+of their use.
+
+\section2 createComponent(url file)
+ This function takes the URL of a QML file as its only argument. It returns
+ a component object which can be used to create and load that QML file.
+
+ Example QML script is below. Remember that QML files that might be loaded
+ over the network cannot be expected to be ready immediately.
+ \code
+ var component;
+ var sprite;
+ function finishCreation(){
+ if(component.isReady()){
+ sprite = component.createObject();
+ if(sprite == 0){
+ // Error Handling
+ }else{
+ sprite.parent = page;
+ sprite.x = 200;
+ //...
+ }
+ }else if(component.isError()){
+ // Error Handling
+ }
+ }
+
+ component = createComponent("Sprite.qml");
+ if(component.isReady()){
+ finishCreation();
+ }else{
+ component.statusChanged.connect(finishCreation);
+ }
+ \endcode
+
+ If you are certain the files will be local, you could simplify to
+
+ \code
+ component = createComponent("Sprite.qml");
+ sprite = component.createObject();
+ if(sprite == 0){
+ // Error Handling
+ console.log(component.errorsString());
+ }else{
+ sprite.parent = page;
+ sprite.x = 200;
+ //...
+ }
+ \endcode
+
+ If you want to just create an arbitrary string of QML, instead of
+ loading a QML file, consider the createQmlObject() function.
+
+\section2 createQmlObject(string qml, object parent, string filepath)
+ Creates a new object from the specified string of QML. It requires a
+ second argument, which is the id of an existing QML object to use as
+ the new object's parent. If a third argument is provided, this is used
+ for error reporting as the filepath that the QML came from.
+
+ Example (where targetItem is the id of an existing QML item):
+ \code
+ newObject = createQmlObject('import Qt 4.6; Rectangle {color: "red"; width: 20; height: 20}',
+ targetItem, "dynamicSnippet1");
+ \endcode
+
+ This function is intended for use inside QML only. It is intended to behave
+ similarly to eval, but for creating QML elements.
+
+ Returns the created object, or null if there is an error. In the case of an
+ error, details of the error are output using qWarning().
+
+ Note that this function returns immediately, and therefore may not work if
+ the QML loads new components. If you are trying to load a new component,
+ for example from a QML file, consider the createComponent() function
+ instead. 'New components' refers to external QML files that have not yet
+ been loaded, and so it is safe to use createQmlObject to load built-in
+ components.
+
+\section1 Asynchronous JavaScript and XML
+QML script supports the XMLHttpRequest object, which can be used to asynchronously obtain data from over a network.
+\section2 XMLHttpRequest()
+In QML you can construct an XMLHttpRequest object just like in a web browser! TODO: Real documentation for this object.
+\section1 Offline Storage API
+
+The \c openDatabase() and related functions
+provide the ability to access local offline storage in an SQL database.
+
+These databases are user-specific and QML-specific. They are stored in the \c Databases subdirectory
+of QmlEngine::offlineStoragePath(), currently as SQLite databases.
+
+The API conforms to the Synchronous API of the HTML5 Web Database API,
+\link http://www.w3.org/TR/2009/WD-webdatabase-20091029/ W3C Working Draft 29 October 2009\endlink.
+
+The API can be used from JavaScript functions in your QML:
+
+\quotefile declarative/sql/hello.qml
+
+When a database is first created, an INI file is also created specifying its characteristics:
+
+\table
+\header \o \bold {Key} \o \bold {Value}
+\row \o Name \o The name of the database passed to \c openDatabase()
+\row \o Version \o The version of the database passed to \c openDatabase()
+\row \o Description \o The description of the database passed to \c openDatabase()
+\row \o EstimatedSize \o The estimated size of the database passed to \c openDatabase()
+\row \o Driver \o Currently "QSQLITE"
+\endtable
+
+This data can be used by application tools.

+\page qml-integration.html
+\title Integrating QML with existing Qt UI code
+
+If you have existing Qt UI code which does not use QML you can still
+add QML to your UI, without having to rewrite it.
+
+\section1 Adding QML to a \l{QWidget} based UI
+If you have an existing QWidget based UI you can simply write new custom
+widgets in QML. To integrate them into your application you can create a
+QmlView widget, and load the QML file into that. You'll then have a new widget
+containing your declarative UI, and you can interact with it through the
+QmlView interface. The one drawback of this approach is that QmlView is a lot
+heavier than a QWidget in terms of memory consumption and initialization speed,
+and so having large numbers of them may lead to performance degredation.
+
+For a smooth transition from a QWidget based UI to a QML based UI, simply
+rewrite your widgets in QML one at a time, using the above method. When
+all of your widgets are written in QML you can rewrite your main widget in
+QML, so as to load the other widgets in QML instead of using QmlViews. Then
+you just load the main QML file on startup.
+
+Keep in mind that QWidgets were designed for different sorts of UIs than QML
+was, and so it is not always a good idea to switch. QWidgets are a better
+choice if your UI is comprised of a small number of complex and static
+elements, and QML is a better choice if your UI is comprised of a large number
+of simple and dynamic elements.
+
+\section1 Adding QML to a QGraphicsView based UI
+If you have an existing Graphics View based UI you can create new items in QML,
+and use \l{QmlComponent} to create \l{QGraphicsObject}s from the QML files. These
+\l{QGraphicsObject}s can then be placed into your \l{QGraphicsScene} using \l{QGraphicsScene::addItem}
+or by reparenting them to an item already in the \l{QGraphicsScene}.
+
+Example, for local QML files:
+
+\code
+QGraphicsScene* scene = new QGraphicsScene;
+QmlEngine *engine = new QmlEngine;
+QmlComponent component(engine, QUrl::fromLocalFile(filename));
+QGraphicsObject *object =
+ qobject_cast<QGraphicsObject *>(component.create());
+scene->addItem(object);
+\endcode
+
+\section1 Using existing QGraphicsWidgets in QML
+Another way of integrating with a QGraphicsView based UI is to expose your
+existing QGraphicsWidgets to QML, and constructing your scene in QML. Note that
+this approach will not work with QGraphicsItems which are not QGraphicsWidgets,
+and that this approach allows you to integrate new items written in QML
+without using the above method.
+
+You can make custom C++ types
+available in QML using the pair of macros listed in \l{Extending QML}.
+While this is normally only useful for
+types that were designed for QML use, in conjunction with the
+\l{GraphicsObjectContainer} element QGraphicsWidget subclasses can also be
+used effectively (if they were designed, like QGraphicsWidget, to be controllable through Qt's property system).
+This way you can write your UI using QML, without having to rewrite your existing items.
+
+For details on implementing this approach see \l{Extending QML} page for details on exposing your C++ types,
+and the \l{GraphicsObjectContainer} documentation for details about using it to wrap QGraphicsWidgets.

+\page qmljavascript.html
+\title JavaScript Blocks
+
+QML encourages building UIs declaratively, using \l {Property Binding} and the
+composition of existing \l {QML Elements}. If imperative code is required to implement
+more advanced behavior, the \l Script element can be used to add JavaScript code directly
+to a QML file, or to include an external JavaScript file.
+
+The \l Script element is a QML language \e intrinsic. It can be used anywhere in a
+QML file, \e except as the root element of a file or sub-component, but cannot be
+assigned to an object property or given an id. The included JavaScript is evaluated
+in a scope chain. The \l {QML Scope} documentation covers the specifics of scoping
+in QML.
+
+A restriction on the JavaScript used in QML is that you cannot add new members to the
+global object. This happens transparently when you try to use a variable without
+declaring it, and so declaring local variables is required when using Java script in
+QML.
+
+The global object in QML has a variety of helper functions added to it, to aid UI
+implementation. See \l{QML Global Object} for further details.
+
+Note that if you are adding a function that should be called by external elements,
+you do not need the \l Script element. See \l {Extending types from QML#Adding new methods}
+{Adding new methods} for information about adding slots that can be called externally.
+
+\section1 Inline Script
+
+Small blocks of JavaScript can be included directly inside a \l {QML Document} as
+the body of the \l Script element.
+
+\code
+Rectangle {
+ Script {
+ function factorial(a) {
+ a = Integer(a);
+ if (a <= 0)
+ return 1;
+ else
+ return a * factorial(a - 1);
+ }
+ }
+}
+\endcode
+
+Good programming practice dictates that only small script snippets should be written
+inline. QML prohibits the declaration of anything other than functions in an inline
+script block. For example, the following script is illegal as an inline script block
+as it declares the non-function variable \c lastResult.
+
+\code
+// Illegal inline code block
+var lastResult = 0
+function factorial(a) {
+ a = Integer(a);
+ if (a <= 0)
+ lastResult = 1;
+ else
+ lastResult = a * factorial(a - 1);
+ return lastResult;
+}
+\endcode
+
+\section1 Including an External File
+
+To avoid cluttering the QML file, large script blocks should be in a separate file.
+The \l Script element's \c source property is used to load script from an external
+file.
+
+If the previous factorial code that was illegal as an inline script block was saved
+into a "factorial.js" file, it could be included like this.
+
+\code
+Rectangle {
+ Script {
+ source: "factorial.js"
+ }
+}
+\endcode
+
+The \c source property may reference a relative file, or an absolute path. In the
+case of a relative file, the location is resolved relative to the location of the
+\l {QML Document} that contains the \l Script element. If the script file is not
+accessible, an error will occur. If the source is on a network resource, the
+enclosing QML document will remain in the \l {QmlComponent::status()}{waiting state}
+until the script has been retrieved.
+
+\section1 Running Script at Startup
+
+It is occasionally necessary to run a block of JavaScript code at application (or
+component instance) "startup". While it is tempting to just include the startup
+script as \e {global code} in an external script file, this can have severe limitations
+as the QML environment may not have been fully established. For example, some objects
+might not have been created or some \l {Property Binding}s may not have been run.
+\l {QML Script Restrictions} covers the exact limitations of global script code.
+
+The QML \l Component element provides an \e attached \c onCompleted property that
+can be used to trigger the execution of script code at startup after the
+QML environment has been completely established.
+
+The following QML code shows how to use the \c Component::onCompleted property.
+
+\code
+Rectangle {
+ Script {
+ function startupFunction() {
+ // ... startup code
+ }
+ }
+
+ Component.onCompleted: startupFunction();
+}
+\endcode
+
+Any element in a QML file - including nested elements and nested QML component
+instances - can use this attached property. If there is more than one script to
+execute at startup, they are run sequentially in an undefined order.
+
+\section1 QML Script Restrictions
+
+QML \l Script blocks contain standard JavaScript code. QML introduces the following
+restrictions.
+
+\list
+\o Script code cannot modify the global object.
+
+In QML, the global object is constant - existing properties cannot be modified or
+deleted, and no new properties may be created.
+
+Most JavaScript programs do not explicitly modify the global object. However,
+JavaScript's automatic creation of undeclared variables is an implicit modification
+of the global object, and is prohibited in QML.
+
+Assuming that the \c a variable does not exist in the scope chain, the following code
+is illegal in QML.
+
+\code
+// Illegal modification of undeclared variable
+a = 1;
+for (var ii = 1; ii < 10; ++ii) a = a * ii;
+ console.log("Result: " + a);
+\endcode
+
+It can be trivially modified to this legal code.
+
+\code
+var a = 1;
+for (var ii = 1; ii < 10; ++ii) a = a * ii;
+ console.log("Result: " + a);
+\endcode
+
+Any attempt to modify the global object - either implicitly or explicitly - will
+cause an exception. If uncaught, this will result in an warning being printed,
+that includes the file and line number of the offending code.
+
+\o Global code is run in a reduced scope
+
+During startup, if a \l Script block includes an external file with "global"
+code, it is executed in a scope that contains only the external file itself and
+the global object. That is, it will not have access to the QML objects and
+properties it \l {QML Scope}{normally would}.
+
+Global code that only accesses script local variable is permitted. This is an
+example of valid global code.
+
+\code
+var colors = [ "red", "blue", "green", "orange", "purple" ];
+\endcode
+
+Global code that accesses QML objects will not run correctly.
+
+\code
+// Invalid global code - the "rootObject" variable is undefined
+var initialPosition = { rootObject.x, rootObject.y }
+\endcode
+
+This restriction exists as the QML environment is not yet fully established.
+To run code after the environment setup has completed, refer to
+\l {Running Script at Startup}.

+\page optimizing-performance.html
+\target optimizing-performance
+\title Optimizing Performance in QML
+
+The Qt Declarative module includes several tools to help measure performance.
+
+\section1 Performance Logging
+
+The declarative module uses the functionality provided by QPerformanceLog to log performance information. To see this information you can add the following to src.pro:
+
+\code
+DEFINES += Q_ENABLE_PERFORMANCE_LOG
+\endcode
+
+The performance information will be printed to screen on a QML application startup, or when running the viewer can be forced at anytime by pressing 'F3' on the keyboard.
+
+Additional logging can be enabled by adding the relevant categories to qfxperf.h and qfxperf.cpp.
+
+For example, to measure the cost of calculating the size of a text item, you would first define a TextSize category by adding the following:
+
+\code
+//in qfxperf.h
+Q_DECLARE_PERFORMANCE_METRIC(TextSize);
+
+//in qfxperf.cpp
+Q_DEFINE_PERFORMANCE_METRIC(TextSize, "Text Size Calculation");
+\endcode
+
+You could then use this category in the code:
+
+\code
+void QmlGraphicsText::updateSize()
+{
+ QmlPerfTimer<QmlPerf::TextSize> perf;
+ ...
+}
+\endcode
+
+Because there is no cost for a QmlPerfTimer when Q_ENABLE_PERFORMANCE_LOG is not defined, this line can persist in the code and be used to help detect performance bottlenecks and regressions. See the QPerformanceLog documentation for more information on this performance framework.
+
+\section1 FPS Measurements
+
+When running the viewer, pressing 'F2' on the keyboard while a QML program is running will cause information on cost-per-frame and frames-per-second (FPS) to be printed to the console.
+
+The information printed includes:
+\list
+\o \e repaint(): the total time spent painting.
+\o \e paint(): the time spent by Qt painting.
+\o \e timeBetweenFrames: the total time spent per frame. This number minus repaint() gives a good idea of how much time is spent on things besides painting. A high number here with a low number for repaint() indicates expensive calculations happening each frame.
+\endlist
+
+\section1 Improving Performance
+
+The following tips can help decrease startup time for QML-based appications.
+
+\section2 Images
+
+\list
+\o Use jpg instead of png for photo-like images. On the N810, this can save 150ms for a large (320x480) image.
+
+\o If you are configuring Qt, configure out any image plugins you don't plan to support (mng and svg are the most expensive). On the N810, this can save 75-100ms startup time. For example:
+
+\code
+configure -no-libmng -no-svg -no-libtiff
+\endcode
+
+\o In some cases running pngcrush, optipng, gifsicle or other similar tools can give some improvement.
+
+We are also investigating support for the loading of uncompressed images. This will provide opportunites to decrease startup time at the cost of increased storage space.
+\endlist
+
+\section2 Fonts
+
+\list
+\o Use qpf instead of ttf. When using multiple font sizes and weights on the N810, this can save 125ms startup time compared to a ttf 'clean' run, and 40-50ms on subsequent runs (ttfs are shared by open applications).

+\page qmlmodules.html
+\title Modules
+
+A \bold module is a collection of QML types.
+
+To use types from a module it must be imported using the \c import statement. Successive
+import statements override earlier import statements, however, since imports have version
+qualifiers, changes in modules do not alter the semantics of imports.
+
+\section1 Importing Types Defined in C++
+
+Types \link adding-types defined in C++\endlink can be from types your application defines, standard QML types,
+or types defined in plugins. To use any such types, you must import
+the module defining them. For example, to use types from Qt, import it:
+
+\code
+import Qt 4.6
+\endcode
+
+This makes available all types in Qt that were available in Qt 4.6, regardless of the
+actual version of Qt executing the QML. So even if Qt 4.7 adds a type that would conflict
+with a type you defined while using 4.6, that type is not imported, so there is no conflict.
+
+Types defined by plugins are made using QmlModulePlugin. Installed plugins and QML files
+can both contribute types to the same module.
+
+
+\section1 Importing Types Defined in QML
+
+When importing types \link components defined using QML\endlink, the syntax depends
+on whether or not the types are installed on the system.
+
+
+\section2 Installed QML Files
+
+To import types defined in QML files that are installed on the system running the
+QML, a URI import is used:
+
+\code
+import com.nokia.Example 1.0
+\endcode
+
+Files imported in this way are found on the paths added by QmlEngine::addImportPath(),
+which by default only inludes \c $QTDIR/qml, so the above would make available those types
+defined in \c $QTDIR/qml/com/nokia/Example which are specified as being in version 1.0.
+Installed plugins and QML files can both contribute types to the same module.
+
+The specification of types to versions is given by a special file, \c qmldir which must
+exist in the module directory. The syntax is described below.
+
+The \c -L option to the \l {qmlviewer}{viewer} application also adds paths to the import path.
+
+
+\section2 Local QML Files
+
+To import types defined in QML files in directories relative to the file importing them,
+a quoted import directory is used:
+
+\code
+import "path"
+\endcode
+
+This allows all components defined in the directory \c path to be used in
+the component where this statement appears.
+
+In this case, and only this case, it is not necessary for the module directory to include
+a \c qmldir file, nor is it necessary to provide a version qualifier. The basis of this is
+that the files in the subdirectory are assumed to be packaged with the importer, and therefore
+they form a single versioned unit.
+
+
+\section2 Remote QML Files
+
+To import types defined in QML file at arbitrary network locations, a quoted absolute URL is used:
+
+\code
+import "http://url/.../" 1.0
+\endcode
+
+This works the same as for relative directory imports, except that the target location \e must
+include a \c qmldir file, and a version qualifier must be given.
+
+
+\section2 The \c qmldir File
+
+Directories of installed files and remote content must include a file \c qmldir which specifies the
+mapping from all type names to versioned QML files. It is a list of lines of the form:
+
+\code
+# <Comment>
+<TypeName> <InitialVersion> <File>
+\endcode
+
+<TypeName> is the type being made available; <InitialVersion> is a version
+number like \c 4.0; <File> is the (relative)
+file name of the QML file defining the type.
+
+The same type can be provided by different files in different versions, in which
+case later earlier versions (eg. 1.2) must precede earlier versions (eg. 1.0),
+since the \e first name-version match is used.
+
+Installed files do not need to import the module of which they are a part, as they can refer
+to the other QML files in the module as relative (local) files.
+
+Installed and remote files \e must be referred to by version information described above,
+local files \e may have it.
+
+The versioning system ensures that a given QML file will work regardless of the version
+of installed software, since a versioned import \e only imports types for that version,
+leaving other identifiers available, even if the actual installed version might otherwise
+use those identifiers.
+
+
+\section1 Namespaces - Named Imports
+

+\page qmlnetwork.html
+\title Network Transparency
+
+QML supports network transparency by using URLs (rather than file names) for all
+references from a QML document to other content:
+
+\qml
+Image {
+ source: "http://www.example.com/images/logo.png"
+}
+\endqml
+
+Since a \e relative URL is the same
+as a relative file, development of QML on regular file systems remains simple:
+
+\qml
+Image {
+ source: "images/logo.png"
+}
+\endqml
+
+Network transparency is supported throughout QML, for example:
+
+\list
+\o Scripts - the \c source property of \l Script is a URL
+\o Fonts - the \c source property of FontLoader is a URL
+\o WebViews - the \c url property of WebView (obviously!)
+\endlist
+
+Even QML types themselves can be on the network - if \l qmlviewer is used to load
+\tt http://example.com/mystuff/Hello.qml and that content refers to a type "World", this
+will load from \tt http://example.com/mystuff/World.qml just as it would for a local file.
+Any other resources that \tt Hello.qml referred to, usually by a relative URL, would
+similarly be loaded from the network.
+
+
+\section1 Relative vs. Absolute URLs
+
+Whenever an object has a property of type URL (QUrl), assigning a string to that
+property will actually assign an absolute URL - by resolving the string against
+the URL of the document where the string is used.
+
+For example, consider this content in \tt{http://example.com/mystuff/test.qml}:
+
+\qml
+Image {
+ source: "images/logo.png"
+}
+\endqml
+
+The \l Image source property will be assigned \tt{http://example.com/mystuff/images/logo.png},
+but while the QML is being developed, in say \tt C:\\User\\Fred\\Documents\\MyStuff\\test.qml, it will be assigned
+\tt C:\\User\\Fred\\Documents\\MyStuff\\images\\logo.png.
+
+If the string assigned to a URL is already an absolute URL, then "resolving" does
+not change it and the URL is assigned directly.
+
+
+\section1 Progressive Loading
+
+Because of the declarative nature of QML and the asynchronous nature of network resources,
+objects which reference network resource generally change state as the network resource loads.
+For example, an Image with a network source will initially have
+a \c width and \c height of 0, a \c status of \c Loading, and a \c progress of 0.0.
+While the content loads, the \c progress will increase until
+the content is fully loaded from the network,
+at which point the \c width and \c height become the content size, the \c status becomes \c Ready, and the \c progress reaches 1.0.
+Applications can bind to these changing states to provide visual progress indicators where appropriate, or simply
+bind to the \c width and \c height as if the content was a local file, adapting as those bound values change.
+
+Note that when objects reference local files they immediately have the \c Ready status, but applications wishing
+to remain network transparent should not rely on this. Future versions of QML may also use asynchronous local file I/O
+to improve performance.
+
+
+\section1 Accessing Network Services
+
+QML types such as XmlListModel, and JavaScript classes like XMLHttpRequest are intended
+entirely for accessing network services, which usually respond with references to
+content by URLs that can then be used directly in QML. For example, using these facilities
+to access an on-line photography service would provide the QML application with URLs to
+photographs, which can be directly set on an \l Image \c source property.
+
+See the \tt demos/declarative/flickr for a real demonstration of this.
+
+
+\section1 Configuring the Network Access Manager
+
+All network access from QML is managed by a QNetworkAccessManager set on the QmlEngine which executes the QML.
+By default, this is an unmodified Qt QNetworkAccessManager. You may set a different manager using
+QmlEngine::setNetworkAccessManager() as appropriate for the policies of your application.
+For example, the \l qmlviewer tool sets a new QNetworkAccessManager which
+trusts HTTP Expiry headers to avoid network cache checks, allows HTTP Pipelining, adds a persistent HTTP CookieJar,
+a simple disk cache, and supports proxy settings.
+
+
+\section1 QRC Resources
+
+One of the URL schemes built into Qt is the "qrc" scheme. This allows content to be compiled into
+the executable using \l{The Qt Resource System}. Using this, an executable can reference QML content
+that is compiled into the executable:
+
+\code
+ QmlView *canvas = new QmlView;
+ canvas->setUrl(QUrl("qrc:/dial.qml"));
+\endcode
+
+The content itself can then use relative URLs, and so be transparently unaware that the content is
+compiled into the executable.
+
+
+\section1 Limitations
+
+The \c import statement is only network transparent if it has an "as" clause.
+
+More specifically:
+\list
+\o \c{import "dir"} only works on local file systems
+\o \c{import libraryUri} only works on local file systems
+\o \c{import "dir" as D} works network transparently
+\o \c{import libraryUrl as U} works network transparently
+\endlist

+\page propertybinding.html
+\title Property Binding
+
+Property binding is a declarative way of specifying the value of a property. Binding allows
+a property's value to be expressed as an JavaScript expression that defines the value relative
+to other property values or data accessible in the application. The property value is
+automatically kept up to date if the other properties or data values change.
+
+Property bindings are created implicitly in QML whenever a property is assigned an JavaScript
+expression. The following QML uses two property bindings to connect the size of the rectangle
+to that of \c otherItem.
+
+\code
+Rectangle {
+ width: otherItem.width
+ height: otherItem.height
+}
+\endcode
+
+QML extends a standards compliant JavaScript engine, so any valid JavaScript expression can be
+used as a property binding. Bindings can access object properties, make function calls and even
+use builtin JavaScript objects like \e {Date} and \e {Math}. Assigning a constant value to a
+property can even be thought of as a binding - afterall, a constant is a valid JavaScript
+expression! Here are some examples of more complex bindings:
+
+\code
+Rectangle {
+ Script {
+ function calculateMyHeight() {
+ return Math.max(otherItem.height, thirdItem.height);
+ }
+ }
+
+ anchors.centerIn: parent
+ width: Math.min(otherItem.width, 10)
+ height: calculateMyHeight()
+ color: { if (width > 10) "blue"; else "red" }
+}
+\endcode
+
+Being JavaScript expressions, bindings are evaluated in a scope chain. The \l {QML Scope}
+documentation covers the specifics of scoping in QML.
+
+\list
+\o When does a binding not get updated?
+\o Scope
+\o Assigning a constant/other binding clears existing binding
+\o Loops
+\o Using model data
+\endlist
+
+\section1 Binding Element
+
+The implicit binding syntax shown previously is easy to use and works perfectly for most uses
+of bindings. In some advanced cases, it is necessary to create bindings explicitly using the
+\l Binding element.
+
+For example, to bind a property exposed from C++ (\c system.brightness) to a value
+coming from QML (\c slider.value), you could use the Binding element as follows:
+\qml
+Binding {
+ target: system
+ property: "brightness"
+ value: slider.value
+}
+\endqml

+\title Debugging QML
+
+\section1 Logging
+
+\c console.log can be used to print debugging information to the console. For example:
+
+\qml
+Rectangle {
+ width: 200; height: 200
+ MouseRegion {
+ anchors.fill: parent
+ onClicked: console.log("clicked")
+ }
+}
+\endqml
+
+\section1 Debugging Transitions
+
+When a transition doesn't look quite right, it can be helpful to view it in slow
+motion to see what is happening more clearly. \l {qmlviewer} provides a
+"Slow Down Animations" menu option to facilitate this.
+
+
+\section1 The QML Inspector
+
+The \c qmldebugger tool provides an experimental inspector to aid with debugging.
+It can be run as a Qt Creator plugin or as a standalone application.
+
+\section2 Qt Creator plugin
+
+The Qt Creator plugin currently builds against Qt Creator 1.3.
+
+To build the Qt Creator plugin:
+
+\list
+\o Set an environment variable \c CREATOR_SRC_DIR that points to the Qt Creator
+ source directory
+\o Set an environment variable \c CREATOR_BUILD_DIR that points to the Qt Creator
+ build directory
+\o Run \c qmake on \c $QTDIR/tools/qmldebugger/qmldebugger.pro
+\endlist
+
+This builds the plugin into your Qt Creator installation.
+
+The plugin adds a "QML Inspect" mode into Qt Creator that provides:
+
+\list
+\o An object tree showing all objects and their children
+\o The current property values for the object selected in the object tree
+ (this table is dynamically updated for all properties that have property changed
+ notifications)
+\o An expression evaluator for querying and setting values dynamically
+\o A table of watched properties (double-click on a property in the property
+ table to add it to the watch table)
+\o A graph that shows the frame rate of your application
+\endlist
+
+
+To start the debugger, open a QML project and click the "QML Inspect" mode, then click the green
+"play" button in the toolbar of the bottom-right debugger window.
+
+\image qmldebugger-creator.png
+
+
+\section2 Standalone qmldebugger tool
+
+To run the standalone \c qmldebugger tool, set an environment variable \c QML_DEBUG_SERVER_PORT
+to an available port number and run the \c qmlviewer. For example:
+
+\code
+ QML_DEBUG_SERVER_PORT=3768 qmlviewer myqmlfile.qml
+\endcode
+
+Then in another process, start the \c qmldebugger tool, enter the port number into the corresponding spinbox
+in the top right hand corner, and press the "Connect" button.

+\page qmldocuments.html
+\title QML Documents
+
+A QML document is a block of QML source code. QML documents generally correspond to files
+stored on a disk or network resource, but can also be constructed directly from text data.
+
+Here is a simple QML document:
+
+\code
+import Qt 4.6
+
+Rectangle {
+ width: 240; height: 320;
+
+ resources: [
+ Component {
+ id: contactDelegate
+ Text {
+ text: modelData.firstName + " " + modelData.lastName
+ }
+ }
+ ]
+
+ ListView {
+ anchors.fill: parent
+ model: contactModel
+ delegate: contactDelegate
+ }
+}
+\endcode
+
+QML documents are always encoded in UTF-8 format.
+
+A QML document always begins with one or more import statements. To prevent elements
+introduced in later versions from affecting existing QML programs, the element types
+available within a document are controlled by the imported QML \l {Modules}. That is,
+QML is a \e versioned language.
+
+Syntactically a QML document is self contained; QML does \e not have a preprocessor that
+modifies the document prior to presentation to the QML runtime. \c import statements
+do not "include" code in the document, but instead instruct the QML runtime on how to
+resolve type references found in the document. Any type reference present in a QML
+document - such as \c Rectangle and \c ListView - including those made within an
+\l {JavaScript Block} or \l {Property Binding}s, are \e resolved based exclusively on the
+import statements. QML does not import any modules by default, so at least one \c import
+statement must be present or no elements will be available!
+
+A QML document defines a single, top-level \l {QmlComponent}{QML component}. A QML component
+is a template that is interpreted by the QML runtime to create an object with some predefined
+behaviour. As it is a template, a single QML component can be "run" multiple times to
+produce several objects, each of which are said to be \e instances of the component.
+
+Once created, instances are not dependent on the component that created them, so they can
+operate on independent data. Here is an example of a simple "button" component that is
+instantiated four times, each with a different value for its \c text property.
+
+\table
+\row
+\o
+\raw HTML
+<table><tr><td>
+\endraw
+\code
+import Qt 4.6
+
+BorderImage {
+ property alias text: textElement.text
+ width: 100; height: 30; source: "images/toolbutton.sci"
+
+ Text {
+ id: textElement
+ anchors.centerIn: parent
+ font.pointSize: 20
+ style: Text.Raised
+ color: "white"
+ }
+}
+\endcode
+\raw HTML
+</td> <td>
+\endraw
+\image anatomy-component.png
+\raw HTML
+</td> </tr> </table>
+\endraw
+\endtable
+
+In addition to the top-level component that all QML documents define, documents may also
+include additional \e inline components. Inline components are declared using the
+\l Component element, as can be seen in the first example above. Inline components share
+all the characteristics of regular top-level components and use the same \c import list as their
+containing QML document. Components are one of the most basic building blocks in QML, and are
+frequently used as "factories" by other elements. For example, the \l ListView element uses the
+\c delegate component as the template for instantiating list items - each list item is just a
+new instance of the component with the item specific data set appropriately.
+
+Like other \l {QML Elements}, the \l Component element is an object and must be assigned to a
+property. \l Component objects may also have an object id. In the first example on this page,
+the inline component is added to the \l Rectangle's \c resources list, and then
+\l {Property Binding} is used to assign the \l Component to the \l ListView's \c delegate
+property. While using property binding allows the \l Component object to be shared (for example,
+if the QML document contained multiple \l ListView's with the same delegate), in this case the
+\l Component could have been assigned directly to the \l ListView's \c delegate. The QML
+language even contains a syntactic optimization when assigning directly to a component property
+for this case where it will automatically insert the \l Component tag.
+
+These final two examples are behaviorally identical to the original document.

+\title QML Internationalization
+
+\section1 Overview
+
+Strings in QML can be marked for translation using the qsTr(), qsTranslate(),
+QT_TR_NOOP(), and QT_TRANSLATE_NOOP() functions.
+
+For example:
+\qml
+Text { text: qsTr("Pictures") }
+\endqml
+
+These functions are standard QtScript functions; for more details see
+QScriptEngine::installTranslatorFunctions().
+
+QML relies on the core internationalization capabilities provided by Qt. These
+capabilities are described more fully in:
+\list
+\o \l {Internationalization with Qt}
+\o \l {Qt Linguist Manual}
+\endlist
+
+You can test a translation in \l {qmlviewer} using the -translation option.
+
+\section1 Example
+
+First we create a simple QML file with text to be translated. The string
+that needs to be translated is enclosed in a call to \c qsTr().
+
+hello.qml:
+\qml
+import Qt 4.6
+
+Rectangle {
+ width: 200; height: 200
+ Text { text: qsTr("Hello"); anchors.centerIn: parent }
+}
+\endqml
+
+Next we create a translation source file using lupdate:
+\code
+lupdate hello.qml -ts hello.ts
+\endcode
+
+Then we open \c hello.ts in \l {Linguist}, provide a translation
+and create the release file \c hello.qm.
+
+Finally, we can test the translation in qmlviewer:
+\code
+qmlviewer -translation hello.qm hello.qml
+\endcode

+\page qmlintroduction.html
+\title Introduction to the QML language
+
+\tableofcontents
+
+QML is a declarative language designed to describe the user interface of a
+program: both what it looks like, and how it behaves. In QML, a user
+interface is specified as a tree of objects with properties.
+
+This introduction is meant for those with little or no programming
+experience. JavaScript is used as a scripting language in QML, so you may want
+to learn a bit more about it (\l{JavaScript: The Definitive Guide}) before diving
+deeper into QML. It's also helpful to have a basic understanding of other web
+technologies like HTML and CSS, but it's not required.
+
+\section1 Basic QML Syntax
+
+QML looks like this:
+
+\code
+Rectangle {
+ width: 200
+ height: 200
+ color: "white"
+ Image {
+ source: "pics/logo.png"
+ anchors.centerIn: parent
+ }
+}
+\endcode
+
+Objects are specified by their type, followed by a pair of braces. Object
+types always begin with a capital letter. In the above example, there are
+two objects, a \l Rectangle, and an \l Image. Between the braces, we can specify
+information about the object, such as its properties.
+
+Properties are specified as \c {property: value}. In the above example, we
+can see the Image has a property named \c source, which has been assigned the
+value \c "pics/logo.png". The property and its value are separated by a colon.
+
+Properties can be specified one-per-line:
+
+\code
+Rectangle {
+ width: 100
+ height: 100
+}
+\endcode
+
+or you can put multiple properties on a single line:
+
+\code
+Rectangle { width: 100; height: 100 }
+\endcode
+
+When multiple property/value pairs are specified on a single line, they
+must be separated by a semicolon.
+
+\section1 Expressions
+
+In addition to assigning values to properties, you can also assign
+expressions written in JavaScript.
+
+\code
+Rotation {
+ angle: 360 * 3
+}
+\endcode
+
+These expressions can include references to other objects and properties, in which case
+a \e binding is established: when the value of the expression changes, the property the
+expression has been assigned to is automatically updated to that value.
+
+\code
+Item {
+ Text {
+ id: text1
+ text: "Hello World"
+ }
+ Text {
+ id: text2
+ text: text1.text
+ }
+}
+\endcode
+
+In the example above, the \c text2 object will display the same text as \c text1. If \c text1 is changed,
+\c text2 is automatically changed to the same value.
+
+Note that to refer to other objects, we use their \e id values. (See below for more
+information on the \e id property.)
+
+\section1 QML Comments
+
+Commenting in QML is similar to JavaScript.
+\list
+\o Single line comments start with // and finish at the end of the line.
+\o Multiline comments start with /* and finish with *\/
+\endlist
+
+\quotefile doc/src/snippets/declarative/comments.qml
+
+Comments are ignored by the engine. The are useful for explaining what you
+are doing: for referring back to at a later date, or for others reading
+your QML files.
+
+Comments can also be used to prevent the execution of code, which is
+sometimes useful for tracking down problems.
+
+\code
+Text {
+ text: "Hello world!"
+ //opacity: 0.5
+}
+\endcode
+
+In the above example, the Text object will have normal opacity, since the
+line opacity: 0.5 has been turned into a comment.
+
+\section1 Properties
+\target intro-properties
+
+\section2 Property naming
+
+Properties begin with a lowercase letter (with the exception of \l{Attached Properties}).
+
+\section2 Property types
+
+QML supports properties of many types (see \l{Common QML Types}). The basic types include int,
+real, bool, string, color, and lists.
+
+\code
+Item {
+ x: 10.5 // a 'real' property
+ ...
+ state: "details" // a 'string' property
+ focus: true // a 'bool' property
+}
+\endcode
+
+QML properties are what is known as \e typesafe. That is, they only allow you to assign a value that
+matches the property type. For example, the \c x property of item is a real, and if you try to assign
+a string to it you will get an error.
+
+\badcode
+Item {
+ x: "hello" // illegal!
+}
+\endcode
+
+\section3 The \c id property
+
+Each object can be given a special unique property called an \e id. Assigning an id enables the object
+to be referred to by other objects and scripts.
+
+The first Rectangle element below has an \e id, "myRect". The second Rectange element defines its
+own width by referring to \tt myRect.width, which means it will have the same \tt width
+value as the first Rectangle element.
+
+\code
+Item {
+ Rectangle {
+ id: myRect
+ width: 100
+ height: 100
+ }
+ Rectangle {
+ width: myRect.width
+ height: 200
+ }
+}
+\endcode
+
+Note that an \e id must begin with a lower-case letter or an underscore, and cannot contain characters other than letters, numbers and underscores.
+
+
+\section2 List properties
+
+List properties look like this:
+
+\code
+Item {
+ children: [
+ Image {},
+ Text {}
+ ]
+}
+\endcode
+
+The list is enclosed in square brackets, with a comma separating the
+list elements. In cases where you are only assigning a single item to a
+list, you can omit the square brackets:
+
+\code
+Image {
+ children: Rectangle {}
+}
+\endcode
+
+\section2 Default properties
+
+Each object type can specify one of its list or object properties as its default property.
+If a property has been declared as the default property, the property tag can be omitted.
+
+For example this code:
+\code
+State {
+ changes: [
+ PropertyChanges {},
+ PropertyChanges {}
+ ]
+}
+\endcode
+
+can be simplified to:
+
+\code
+State {
+ PropertyChanges {}
+ PropertyChanges {}
+}
+\endcode
+
+because \c changes is the default property of the \c State type.
+
+\section2 Grouped Properties
+
+In some cases properties form a logical group and use a 'dot' or grouped notation
+to show this.
+
+Grouped properties can be written like this:
+\qml
+Text {
+ font.pixelSize: 12
+ font.bold: true
+}
+\endqml
+
+or like this:
+\qml
+Text {
+ font { pixelSize: 12; bold: true }
+}
+\endqml
+
+In the element documentation grouped properties are shown using the 'dot' notation.
+
+\section2 Attached Properties
+\target attached-properties
+
+Some objects attach properties to another object. Attached Properties
+are of the form \e {Type.property} where \e Type is the type of the
+element that attaches \e property.
+
+For example:
+\code
+Component {
+ id: myDelegate
+ Text {
+ text: "Hello"
+ color: ListView.isCurrentItem ? "red" : "blue"
+ }
+}
+ListView {
+ delegate: myDelegate
+}
+\endcode
+
+The \l ListView element attaches the \e ListView.isCurrentItem property
+to each delegate it creates.
+
+Another example of attached properties is the \l Keys element which
+attaches properties for handling key presses to
+any visual Item, for example:
+
+\code
+Item {
+ focus: true
+ Keys.onSelectPressed: console.log("Selected")
+}
+\endcode
+
+\section2 Signal Handlers
+
+Signal handlers allow actions to be taken in reponse to an event. For instance,
+the \l MouseRegion element has signal handlers to handle mouse press, release
+and click:
+
+\code
+MouseRegion {
+ onPressed: console.log("mouse button pressed")
+}
+\endcode
+
+All signal handlers begin with \e "on".
+
+Some signal handlers include an optional parameter, for example
+the MouseRegion onPressed signal handler has a \e mouse parameter:
+
+\code
+MouseRegion {
+ acceptedButtons: Qt.LeftButton | Qt.RightButton
+ onPressed: if (mouse.button == Qt.RightButton) console.log("Right mouse button pressed")
+}
+\endcode

+\page qmlmodels.html
+\target qmlmodels
+\title Data Models
+
+Some QML Items use Data Models to provide the data to be displayed.
+These items typically require a \e delegate component that
+creates an instance for each item in the model. Models may be static, or
+have items modified, inserted, removed or moved dynamically.
+
+Data is provided to the delegate via named data roles which the
+delegate may bind to. The roles are exposed as properties of the
+\e model context property, though this property is set as a default property
+of the delegate so, unless there is a naming clash with a
+property in the delegate, the roles are usually accessed unqualified. The
+example below would have a clash between he \e color role of the model and
+the \e color property of the Rectangle. The clash is avoided by referencing
+the \e color property of the model by its full name: \e model.color.
+
+\code
+ListModel {
+ id: myModel
+ ListElement { color: "red" }
+ ListElement { color: "green" }
+}
+
+Component {
+ id: myDelegate
+ Rectangle {
+ width: 20; height: 20
+ color: model.color
+ }
+}
+\endcode
+
+A special \e index role containing the index of the item in the model
+is also available.
+
+\e Note: the index role will be set to -1 if the item is removed from
+the model. If you bind to the index role, be sure that the logic
+accounts for the possibility of index being -1, i.e. that the item
+is no longer valid. Usually the item will shortly be destroyed, but
+it is possible to delay delegate destruction in some views via a delayRemove
+attached property.
+
+Models that do not have named roles will have the data provided via
+the \e modelData role. The \e modelData role is also provided for
+Models that have only one role. In this case the \e modelData role
+contains the same data as the named role.
+
+There are a number of QML elements that operate using data models:
+
+\list
+\o ListView
+\o GridView
+\o PathView
+\o \l Repeater
+\endlist
+
+QML supports several types of data model, which may be provided by QML
+or C++ (via QmlContext::setContextProperty(), for example).
+
+\section1 QML Data Models
+
+\section2 ListModel
+
+ListModel is a simple hierarchy of elements specified in QML. The
+available roles are specified by the \l ListElement properties.
+
+\code
+ListModel {
+ id: fruitModel
+ ListElement {
+ name: "Apple"
+ cost: 2.45
+ }
+ ListElement {
+ name: "Orange"
+ cost: 3.25
+ }
+ ListElement {
+ name: "Banana"
+ cost: 1.95
+ }
+}
+\endcode
+
+The above model has two roles, \e name and \e cost. These can be bound
+to by a ListView delegate, for example:
+
+\code
+Component {
+ id: fruitDelegate
+ Row {
+ Text { text: "Fruit: " + name }
+ Text { text: "Cost: $" + cost }
+ }
+}
+ListView {
+ model: fruitModel
+ delegate: fruitDelegate
+}
+\endcode
+
+
+\section2 XmlListModel
+
+XmlListModel allows construction of a model from an XML data source. The roles
+are specified via the \l XmlRole element.
+
+The following model has three roles, \e title, \e link and \e description:
+\code
+XmlListModel {
+ id: feedModel
+ source: "http://rss.news.yahoo.com/rss/oceania"
+ query: "/rss/channel/item"
+ XmlRole { name: "title"; query: "title/string()" }
+ XmlRole { name: "link"; query: "link/string()" }
+ XmlRole { name: "description"; query: "description/string()" }
+}
+\endcode
+
+
+\section2 VisualItemModel
+
+VisualItemModel allows QML items to be provided as a model. This model contains
+both the data and delegate (its child items). This model does not provide any roles.
+
+\code
+ VisualItemModel {
+ id: itemModel
+ Rectangle { height: 30; width: 80; color: "red" }
+ Rectangle { height: 30; width: 80; color: "green" }
+ Rectangle { height: 30; width: 80; color: "blue" }
+ }
+
+ ListView {
+ anchors.fill: parent
+ model: itemModel
+ }
+\endcode
+
+Note that in the above example there is no delegate required.
+The items of the model itself provide the visual elements that
+will be positioned by the view.
+
+
+\section1 C++ Data Models
+
+\section2 QAbstractItemModel
+
+QAbstractItemModel provides the roles set via the QAbstractItemModel::setRoleNames() method.
+
+
+\section2 QStringList
+
+QStringList provides the contents of the list via the \e modelData role:
+
+\table
+\o
+\code
+// main.cpp
+QStringList dataList;
+dataList.append("Fred");
+dataList.append("Ginger");
+dataList.appenf("Skipper");
+
+QmlContext *ctxt = view.rootContext();
+ctxt->setContextProperty("myModel", QVariant::fromValue(&dataList));
+\endcode
+
+\o
+\code
+// main.qml
+ListView {
+ width: 100
+ height: 100
+ anchors.fill: parent
+ model: myModel
+ delegate: Component {
+ Rect {
+ height: 25
+ Text { text: modelData }
+ }
+ }
+}
+\endcode
+\endtable
+
+Note: There is no way for the view to know that the contents of a QStringList
+have changed. If the QStringList is changed, it will be necessary to reset
+the model by calling QmlContext::setContextProperty() again.
+
+
+\section2 QList<QObject*>
+
+QList<QObject*> provides the properties of the objects in the list as roles.
+
+\code
+class DataObject : public QObject
+{
+ Q_OBJECT
+
+ Q_PROPERTY(QString name READ name WRITE setName)
+ Q_PROPERTY(QString color READ color WRITE setColor)
+...
+};
+
+QList<QObject*> dataList;
+dataList.append(new DataObject("Item 1", "red"));
+dataList.append(new DataObject("Item 2", "green"));
+dataList.append(new DataObject("Item 3", "blue"));
+dataList.append(new DataObject("Item 4", "yellow"));
+
+QmlContext *ctxt = view.rootContext();
+ctxt->setContextProperty("myModel", QVariant::fromValue(&dataList));
+\endcode
+
+The properties of the object may then be accessed in the delegate:
+
+\code
+ListView {
+ width: 100
+ height: 100
+ anchors.fill: parent
+ model: myModel
+ delegate: Component {
+ Rectangle {
+ height: 25
+ width: 100
+ color: model.color
+ Text { text: name }
+ }
+ }
+}
+\endcode
+
+Note: There is no way for the view to know that the contents of a QList
+have changed. If the QList is changed, it will be necessary to reset
+the model by calling QmlContext::setContextProperty() again.
+
+
+\section1 Other Data Models
+
+
+\section2 An Integer
+
+An Integer specifies a model containing the integer number of elements.
+There are no data roles.
+
+The following example creates a ListView with five elements:
+\code
+Component {
+ id: itemDelegate
+ Text { text: "I am item number: " + index }
+}
+ListView {
+ model: 5
+ delegate: itemDelegate
+}
+\endcode
+
+
+\section2 An Object Instance
+
+An Object Instance specifies a model with a single Object element. The
+properties of the object are provided as roles.
+
+The example below creates a list with one item, showing the color of the
+\e myText text. Note the use of the fully qualified \e model.color property
+to avoid clashing with \e color property of the Text element in the delegate.
+
+\code
+Rectangle {
+ Text {
+ id: myText
+ text: "Hello"
+ color: "#dd44ee"
+ }
+
+ Component {
+ id: myDelegate
+ Text {
+ text: model.color
+ }
+ }
+ ListView {
+ anchors.fill: parent
+ anchors.topMargin: 30
+ model: myText
+ delegate: myDelegate
+ }
+}
+\endcode

+
+ QML is a language for building the animation rich,
+ highly fluid user interfaces that are becoming common in portable consumer
+ electronics devices such as mobile phones, media players, set-top boxes and
+ netbooks. It is also appropriate for highly custom desktop
+ user interfaces, or special elements in more traditional desktop user interfaces.
+
+ Building fluid applications is done declaratively, rather than procedurally.
+ That is, you specify \e what the UI should look like and how it should behave
+ rather than specifying step-by-step \e how to build it. Specifying a UI declaratively
+ does not just include the layout of the interface items, but also the way each
+ individual item looks and behaves and the overall flow of the application.
+
+ The QML elements provide a sophisticated set of graphical and behavioral building
+ blocks. These different elements are combined together in \l {QML Documents}{QML documents} to build components
+ ranging in complexity from simple buttons and sliders, to complete
+ internet-enabled applications like a \l {http://www.flickr.com}{Flickr} photo browser.

+\title QML States
+
+\section1 Overview
+
+QML states typically describe user interface configurations, including:
+\list
+\o What UI elements are present
+\o The properties of those elements (including how they behave)
+\o What actions are available
+\endlist
+
+A state can also be thought of as a set of batched changes from a default configuration.
+
+Examples of states in modern UI:
+\list
+\o An Address Book application with a 'View Contact' state and an 'Edit Contact' State. In the first state the contact information presented is read-only (using labels), and in the second it is editable (using editors).
+\o A button with a pressed and unpressed state. When pressed the text moves slightly down and to the right, and the button has a slightly darker appearance.
+\endlist
+
+\section1 States in QML
+
+In QML:
+\list
+\o Any object can use states.
+\o There is a default state. The default state can be explicitly set.
+\o A state can affect the properties of other objects, not just the object owning the state (and not just that object's children).
+\endlist
+
+Here is an example of using states. In the default state \c myRect is positioned at 0,0. In the 'moved' state it is positioned at 50,50. Clicking within the mouse region changes the state from the default state to the 'moved' state, thus moving the rectangle.
+
+\qml
+Item {
+ id: myItem
+
+ Rectangle {
+ id: myRect
+ width: 100
+ height: 100
+ color: "red"
+ }
+
+ states: [
+ State {
+ name: "moved"
+ PropertyChanges {
+ target: myRect
+ x: 50
+ y: 50
+ }
+ }
+ ]
+
+ MouseRegion {
+ anchors.fill: parent
+ onClicked: myItem.state = 'moved'
+ }
+}
+\endqml
+
+State changes can be animated using \l{state-transitions}{Transitions}.
+
+For example, adding this code to the above \c {Item {}} element animates the transition to the "moved" state:
+
+\qml
+ transitions: [
+ Transition {
+ NumberAnimation { matchProperties: "x,y"; duration: 500 }
+ }
+ ]
+\endqml
+
+See \l{state-transitions}{Transitions} for more information.
+
+
+Other things you can do in a state change:
+\list
+\o override signal handlers with PropertyChanges
+\o change an item's visual parent with ParentChange
+\o change an item's anchors with AnchorChanges
+\o run some script with StateChangeScript
+\endlist

+ \title Qt Declarative UI Viewer (qmlviewer)
+ \ingroup qttools
+ \keyword qmlviewer
+
+ This page documents the \e{Declarative UI Viewer} for the Qt GUI
+ toolkit. The \c qmlviewer reads a declarative user interface definition
+ (\c .qml) file and displays the user interface it describes.
+
+ qmlviewer is a development tool. It is not intended to be
+ installed in a production environment.
+
+ \section1 Options
+
+ When run with the \c -help option, qmlviewer shows available options.
+
+ \section1 Dummy Data
+
+ One use of qmlviewer is to allow QML files to be viewed stand-alone,
+ rather than being loaded from within a Qt program. Qt applications will
+ usually bind objects and properties into the execution context before
+ running the QML. To stand-in for such bindings, you can provide dummy
+ data: create a directory called "dummydata" in the same directory as
+ the target QML file and create files there with the "qml" extension.
+ All such files will be loaded as QML objects and bound to the root
+ context as a property with the name of the file (without ".qml").
+
+ For example, if the Qt application has a "clock.time" property
+ that is a qreal from 0 to 86400 representing the number of seconds since
+ midnight, dummy data for this could be provided by \c dummydata/clock.qml:
+ \code
+ QtObject { property real time: 12345 }
+ \endcode
+ Any QML can be used in the dummy data files. You could even animate the
+ fictional data!
+
+ \section1 Screen Orientation
+
+ A special piece of dummy data which is integrated into the viewer is
+ a simple orientation property. The orientation can be set via the
+ settings menu in the application, or by pressing Ctrl+T to toggle it.
+
+ To use this from within your QML file, import QmlViewer 1.0 and create a
+ Screen object. This object has a property, orientation, which can be either
+ Screen.Landscape or Screen.Portrait and which can be bound to in your
+ application. An example is below:
+
+\code
+ import QmlViewer 1.0 as QmlViewer
+
+ Item {
+ QmlViewer.Screen { id: qmlviewerScreen }
+ state: (qmlviewerScreen.orientation == QmlViewer.Screen.Landscape) ? 'landscape' : ''
+ }
+\endcode

+\target qtbinding
+\title Using QML in C++ Applications
+
+\tableofcontents
+
+The QML API is split into three main classes - QmlEngine, QmlComponent and QmlContext.
+QmlEngine provides the environment in which QML is run, QmlComponent encapsulates
+\l {QML Documents}, and QmlContext allows applications to expose data to QML component instances.
+
+QML also includes a convenience API, QmlView, for applications that simply want to embed QML
+components into a new QGraphicsView. QmlView covers up many of the details discussed below.
+While QmlView is mainly intended for rapid prototyping it can have uses in production applications.
+
+If you are looking at retrofitting an existing Qt application with QML,
+read \l{Integrating QML with existing Qt UI code}.
+\section1 Basic Usage
+
+Every application requires at least one QmlEngine. A QmlEngine allows the configuration of
+global settings that apply to all the QML component instances - such as the QNetworkAccessManager
+that is used for network communications, and the path used for persistent storage.
+Multiple QmlEngine's are only needed if the application requires these settings to differ
+between QML component instances.
+
+\l {QML Documents} are loaded using the QmlComponent class. Each QmlComponent instance
+represents a single QML document. A QmlComponent can be passed a document URL, or raw text
+representing the content of the document. The document URL can be a local filesystem URL, or
+any network URL supported by QNetworkAccessManager.
+
+QML component instances can then be created by calling the QmlComponent::create() method. Here's
+an example of loading a QML document, and creating an object from it.
+
+\code
+QmlEngine *engine = new QmlEngine(parent);
+QmlComponent component(engine, QUrl("main.qml"));
+QObject *myObject = component.create();
+\endcode
+
+\section1 Exposing Data
+
+QML components are instantiated in a QmlContext. A context allows the application to expose data
+to the QML component instance. A single QmlContext can be used to instantiate all the objects
+used by an application, or several QmlContext can be created for more fine grained control over
+the data exposed to each instance. If a context is not passed to the QmlComponent::create()
+method, the QmlEngine's \l {QmlEngine::rootContext()}{root context} is used. Data exposed through
+the root context is available to all object instances.
+
+\section1 Simple Data
+
+To expose data to a QML component instance, applications set \l {QmlContext::setContextProperty()}
+{context properties} which are then accessible by name from QML \l {Property Binding}s and
+\l {JavaScript Blocks}. The following example shows how to expose a background color to a QML
+file.
+
+\table
+\row
+\o
+\code
+// main.cpp
+QmlContext *windowContext = new QmlContext(engine->rootContext());
+windowContext->setContextProperty("backgroundColor",
+ QColor(Qt::lightsteelblue));
+
+QmlComponent component(&engine, "main.qml");
+QObject *window = component.create(windowContext);
+\endcode
+\o
+\code
+// main.qml
+import Qt 4.6
+
+Rectangle {
+ color: backgroundColor
+
+ Text {
+ anchors.centerIn: parent
+ text: "Hello Light Steel Blue World!"
+ }
+}
+\endcode
+\endtable
+
+Context properties work just like normal properties in QML bindings - if the \c backgroundColor
+context property in the previous example was changed to red, the component object instances would
+all be automatically updated. Note that it is the responsibility of the creator to delete any
+QmlContext it constructs. If the \c windowContext in the example above is no longer needed when
+the \c window component instantiation is destroyed, the \c windowContext must be destroyed
+explicitly. The simplest way to ensure this is to set \c window as \c windowContext's parent.
+
+QmlContexts form a tree - each QmlContext except for the root context has a parent. Child
+QmlContexts effectively inherit the context properties present in their parents. This gives
+applications more freedom in partitioning the data exposed to different QML object instances.
+If a QmlContext sets a context property that is also set in one of its parents, the new context
+property shadows that in the parent. In The following example, the \c background context property
+in \c {Context 1} shadows the \c background context property in the root context.
+
+\image qml-context-tree.png
+
+\section2 Structured Data
+
+Context properties can also be used to expose structured and writable data to QML objects. In
+addition to all the types already supported by QVariant, QObject derived types can be assigned to
+context properties. QObject context properties allow the data exposed to be more structured, and
+allow QML to set values.
+
+The following example creates a \c CustomPalette object, and sets it as the \c palette context
+property.
+
+\code
+class CustomPalette : public QObject
+{
+Q_OBJECT
+Q_PROPERTY(QColor background READ background WRITE setBackground NOTIFY backgroundChanged)
+Q_PROPERTY(QColor text READ text WRITE setText NOTIFY text)
+public:
+ CustomPalette() : m_background(Qt::white), m_text(Qt::black) {}
+
+ QColor background() const { return m_background; }
+ void setBackground(const QColor &c) {
+ if (c != m_background) {
+ m_background = c;
+ emit backgroundChanged();
+ }
+ }
+
+ QColor text() const { return m_text; }
+ void setText(const QColor &c) {
+ if (c != m_text) {
+ m_text = c;
+ emit textChanged();
+ }
+ }
+private:
+ QColor m_background;
+ QColor m_text;
+};
+
+int main(int argc, char **argv)
+{
+ // ...
+
+ QmlContext *windowContext = new QmlContext(engine->rootContext());
+ windowContext->setContextProperty("palette", new CustomPalette);
+
+ QmlComponent component(&engine, "main.qml");
+ QObject *window = component.create(windowContext);
+}
+\endcode
+
+The QML that follows references the palette object, and its properties, to set the appropriate
+background and text colors. When the window is clicked, the palette's text color is changed, and
+the window text will update accordingly.
+
+\code
+// main.qml
+import Qt 4.6
+
+Rectangle {
+ width: 240
+ height: 320
+ color: palette.background
+
+ Text {
+ anchors.centerIn: parent
+ color: palette.text
+ text: "Hello Colorful World!"
+ }
+
+ MouseRegion {
+ anchors.fill: parent
+ onClicked: {
+ palette.text = "blue";
+ }
+ }
+}
+\endcode
+
+To detect when a C++ property value - in this case the \c CustomPalette's \c text property -
+changes, the property must have a corresponding NOTIFY signal. The NOTIFY signal specifies a signal
+that is emitted whenever the property changes value. Implementers should take care to only emit the
+signal if the value \e changes to prevent loops from occuring. Accessing a property from a
+binding that does not have a NOTIFY signal will cause QML to issue a warning at runtime.
+
+\section2 Dynamic Structured Data
+
+If an application is too dynamic to structure data as compile-time QObject types, dynamically
+structured data can be constructed at runtime using the QmlPropertyMap class.
+
+
+\section1 Calling C++ methods from QML
+
+It is possible to call methods of QObject derived types by either exposing the
+methods as public slots, or by marking the methods Q_INVOKABLE.
+
+The C++ methods can also have parameters and return values. QML has support for
+the following types:
+
+\list
+\o bool
+\o unsigned int, int
+\o float, double, qreal
+\o QString
+\o QUrl
+\o QColor
+\o QDate, QTime, QDateTime
+\o QPoint, QPointF
+\o QSize, QSizeF
+\o QRect, QRectF
+\o QVariant
+\endlist
+
+This example toggles the "LED Blinker" when the MouseRegion is clicked:
+
+\table
+\row
+\o
+\code
+// main.cpp
+class LEDBlinker : public QObject
+{
+ Q_OBJECT
+public:
+ LEDBlinker();
+
+ Q_INVOKABLE bool isRunning();
+
+public slots:
+ void start();
+ void stop();
+};
+
+int main(int argc, char **argv)
+{
+ // ...
+
+ QmlContext *context = engine->rootContext();
+ context->setContextProperty("ledBlinker", new LEDBlinker);
+
+ // ...
+}
+\endcode
+\o
+\code
+// main.qml
+import Qt 4.6
+
+Rectangle {
+ MouseRegion {
+ anchors.fill: parent
+ onClicked: {
+ if (ledBlinker.isRunning())
+ ledBlinker.stop()
+ else
+ ledBlicker.start();
+ }
+ }
+}
+\endcode
+\endtable
+
+Note that in this particular example a better way to achieve the same result
+is to have a "running" property. This leads to much nicer QML code:
+
+\table
+\row
+\o
+\code
+// main.qml
+import Qt 4.6
+
+Rectangle {
+ MouseRegion {
+ anchors.fill: parent
+ onClicked: ledBlinker.running = !ledBlinker.running
+ }
+}
+\endcode
+\endtable
+
+
+Of course, it is also possible to call \l {Adding new methods}{functions declared in QML from C++}.
+
+
+\section1 Network Components
+
+If the URL passed to QmlComponent is a network resource, or if the QML document references a
+network resource, the QmlComponent has to fetch the network data before it is able to create
+objects. In this case, the QmlComponent will have a \l {QmlComponent::Loading}{Loading}
+\l {QmlComponent::status()}{status}. An application will have to wait until the component
+is \l {QmlComponent::Ready}{Ready} before calling \l {QmlComponent::create()}.
+
+The following example shows how to load a QML file from a network resource. After creating
+the QmlComponent, it tests whether the component is loading. If it is, it connects to the
+QmlComponent::statusChanged() signal and otherwise calls the \c {continueLoading()} method
+directly. This test is necessary, even for URLs that are known to be remote, just in case
+the component has been cached and is ready immediately.
+
+\code
+MyApplication::MyApplication()
+{
+ // ...
+ component = new QmlComponent(engine, QUrl("http://www.example.com/main.qml"));
+ if (component->isLoading())
+ QObject::connect(component, SIGNAL(statusChanged(QmlComponent::Status)),
+ this, SLOT(continueLoading()));
+ else
+ continueLoading();
+}
+
+void MyApplication::continueLoading()
+{
+ if (component->isError()) {
+ qWarning() << component->errors();
+ } else {
+ QObject *myObject = component->create();
+ }
+}
+\endcode

+
+\section1 Overview
+
+While QML does not require Qt knowledge to use, if you \e are already familar with Qt,
+much of your knowledge is directly relevant to learning and using QML. Of course,
+an application with a UI defined in QML also uses Qt for all the non-UI logic.
+
+\section1 Familiar Concepts
+
+QML provides direct access to the following concepts from Qt:
+
+\list
+ \o QAction - the \l {basicqmlaction}{action} type
+ \o QObject signals and slots - available as functions to call in JavaScript
+ \o QObject properties - available as variables in JavaScript
+ \o QWidget - QmlView is a QML-displaying widget
+ \o Qt models - used directly in data binding (QAbstractItemModel and next generation QListModelInterface)
+\endlist
+
+Qt knowledge is \e required for \l {Extending QML}, and also for \l{Integrating QML with existing Qt UI code}.
+
+\section1 QML Items compared with QWidgets
+
+QML Items are very similar to QWidgets: they define the look and feel of the user interface. (Note that while QWidgets
+haven't traditionally been used to define the look and feel of view delegates, QML Items can be used for this as well.)
+
+There are three structurally different types of QWidget:
+
+\list
+ \o Simple widgets that are not used as parents (QLabel, QCheckBox, QToolButton, etc.)
+ \o Parent widgets that are normally used as parents to other widgets (QGroupBox, QStackedWidget, QTabWidget, etc.)
+ \o Compound widgets that are internally composed of child widgets (QComboBox, QSpinBox, QFileDialog, QTabWidget, etc.)
+\endlist
+
+QML Items also serve these purposes. Each is considered separately below.
+
+\section2 Simple Widgets
+
+The most important rule to remember while implementing a new QmlGraphicsItem in C++
+is that it should not contain any look and feel policies - leave that to the
+QML usage of the item.
+
+As an example, imagine you wanted a reusable Button item. If you therefore
+decided to write a QmlGraphicsItem subclass to implement a button,
+just as QToolButton subclasses QWidget for this purpose, following the rule above, your
+\c QmlGraphicsButton would not have any appearance - just the notions of enabled, triggering, etc.
+
+But there is already an object in Qt that does this: QAction.
+
+QAction is the UI-agnostic essence of QPushButton, QCheckBox, QMenu items, QToolButton,
+and other visual widgets that are commonly bound to a QAction.
+
+So, the job of implementing a checkbox abstraction for QML is already done - it's QAction.
+The look and feel of an action - the appearance of the button, the transition between states,
+and exactly how it respond to mouse, key, or touch input, should all be left for definition
+in QML.
+
+It is illustrative to note that QmlGraphicsTextEdit is built upon QTextControl,
+QmlGraphicsWebView is built upon QWebPage, and ListView uses QListModelInterface,
+just as QTextEdit, QWebView, and QListView are built upon
+those same UI-agnostic components.
+
+The encapsulation of the look and feel that QWidgets gives is important, and for this
+the QML concept of \l {qmldocuments.html}{components} serves the same purpose. If you are building a complete
+suite of applications which should have a consistent look and feel, you should build
+a set of reusable components with the look and feel you desire.
+
+So, to implement your reusable button, you would simply build a QML component.
+
+
+\section2 Parent Widgets
+
+Parent widgets each provide a generic way to interface to one or more arbitrary other widgets.
+A QTabWidget provides an interface to multiple "pages", one of which is visible at any time,
+and a mechnism for selecting among them (the QTabBar). A QScollArea provides scrollbars around
+a widget that is otherwise too large to fit in available space.
+
+Nearly all such components can be created directly in QML. Only a few cases
+which require very particular event handling, such as Flickable, require C++ implementations.
+
+As an example, imagine you decided to make a generic tab widget item to be used
+through your application suite wherever information is in such quantity that it
+needs to be divided up into pages.
+
+A significant difference in the parenting concept with QML compare to QWidgets
+is that while child items are positioned relative to their parents,
+there is no requirement that they be wholy contained ("clipped") to
+the parent (although the clipped property of the child Item does allow
+this where it is needed).
+This difference has rather far-reaching consequences, for example:
+
+\list
+ \o A shadow or highlight around a widget could be a child of that widget.
+ \o Particle effects can flow outside the object where they originate.
+ \o Transitioning animations can "hide" items by visibly moving them beyond the screen bounds.
+\endlist
+
+
+\section2 Compound Widgets
+
+Some widgets provide functionality by composing other widgets as an "implementation detail",
+providing a higher level API to the composition. QSpinBox for example is a line edit and some
+buttons to increase/decrease the edited value. QFileDialog uses a whole host of widgets to
+give the user a way of finding and selecting a file name.
+
+When developing reusable QML Items, you may choose to do the same: build an item composed
+of other items you have already defined.
+
+The only caveat when doing this is to consider the possible animations and transitions that
+users of the compound item might wish to employ. For example, a spinbox might need to smoothly
+transition from an arbitrary Text item, or characters within a Text item, so your spinbox
+item would need to be sufficiently flexible to allow such animation.
+

+\page qmlscope.html
+\title QML Scope
+
+\tableofcontents
+
+\l {Property Binding}s and \l {JavaScript Blocks} are executed in a scope chain automatically
+established by QML when a component instance is constructed. QML is a \e {dynamically scoped}
+language. Different object instances instantiated from the same component can exist in
+different scope chains.
+
+\image qml-scope.png
+
+\section1 JavaScript Variable object
+
+Each binding and script block has its own distinct JavaScript variable object where local
+variables are stored. That is, local variables from different bindings and script blocks never
+conflict.
+
+\section1 Element Type Names
+
+Bindings or script blocks use element type names when accessing \l {Attached Properties} or
+enumeration values. The set of available element names is defined by the import list of the
+\l {QML Documents}{QML Document} in which the the binding or script block is defined.
+
+These two examples show how to access attached properties and enumeration values with different
+types of import statements.
+\table
+\row
+\o
+\code
+import Qt 4.6
+
+Text {
+ id: root
+ scale: root.PathView.scale
+ horizontalAlignment: Text.AlignLeft
+}
+\endcode
+\o
+\code
+import Qt 4.6 as MyQt
+
+Text {
+ id: root
+ scale: root.MyQt.PathView.scale
+ horizontalAlignment: MyQt.Text.AlignLeft
+}
+\endcode
+\endtable
+
+\section1 QML Local Scope
+
+Most variables references are resolved in the local scope. The local scope is controlled by the
+QML component in which the binding or script block was defined. The following example shows
+three different bindings, and the component that dictates each local scope.
+
+\table
+\row
+\o
+\code
+// main.qml
+import Qt 4.6
+
+Rectangle { // Local scope component for binding 1
+ id: root
+ property string text
+
+ Button {
+ text: root.text // binding 1
+ }
+
+ ListView {
+ delegate: Component { // Local scope component for binding 2
+ Rectangle {
+ width: ListView.view.width // binding 2
+ }
+ }
+ }
+
+}
+\endcode
+\o
+\code
+// Button.qml
+import Qt 4.6
+
+Rectangle { // Local scope component for binding 3
+ id: root
+ property string text
+
+ Text {
+ text: root.text // binding 3
+ }
+}
+\endcode
+\endtable
+
+Inside the local scope, four "sub-scopes" exist. Each sub-scope is searched in order when
+resolving a name; names in higher sub-scopes shadow those in lower sub-scopes.
+
+\section2 IDs
+
+IDs present in the component take precendence over other names. The QML engine enforces
+uniqueness of IDs within a component, so their names cannot conflict with one another.
+
+Here is an example of using IDs within bindings:
+
+\code
+Item {
+ id: root
+ width: nested.width
+ Item {
+ id: nested
+ height: root.height
+ }
+}
+\endcode
+
+\section2 Script Methods
+
+Methods declared in script blocks are searched immediately after IDs. In the case of multiple
+script blocks in the one component, the blocks are searched in the order in which they were
+declared - the nesting of script blocks within a component is not significant for name
+resolution.
+
+In the following example, \c {Method 1} shadows \c {Method 2} for the bindings, but not for
+\c {Method 3}.
+
+\code
+Item {
+ Script {
+ function getValue() { return 10; } // Method 1
+ }
+
+ Rectangle {
+ Script {
+ function getValue() { return 11; } // Method 2
+ function getValue2() { return getValue(); } // Method 3
+ }
+
+ x: getValue() // Resolves to Method 1, set to 10
+ y: getValue2() // Resolves to Method 3, set to 11
+ }
+}
+\endcode
+
+\section2 Scope Object
+
+A scope object is associated with each binding and script block. Properties and methods of the
+scope object appear in the scope chain, immediately after \l {Script Methods}.
+
+In bindings and script blocks established explicitly in \l {QML Documents}, the scope object is
+always the element containing the binding or script block. The following example shows two
+bindings, one using grouped properties, and the corresponding scope object. These two bindings
+use the scope object to resolve variable references: \c height is a property on \l Rectangle,
+and \c parent is a property on \l Text.
+
+\code
+Item { // Scope object for Script block 1
+ Script { // Script block 1
+ function calculateValue() { ... }
+ }
+
+ Rectangle { // Scope object for Binding 1 and Script block 2
+ Script { // Script block 2
+ function calculateColor() { ... }
+ }
+ width: height * 2 // Binding 1
+ }
+
+ Text { // Scope object for Binding 2
+ font.pixelSize: parent.height * 0.7 // binding 2
+ }
+}
+\endcode
+
+One notable characteristic of the scope object is its interaction with \l {Attached Properties}.
+As attached properties exist on all objects, an attached property reference that is not
+explicitly prefixed by an id will \e always resolve to the attached property on the scope
+object.
+
+In the following example, \c {Binding 1} will resolve to the attached properties of the
+\l Rectangle element, as intended. However, due to the property search of the scope object,
+\c {Binding 2} will resolve to the attached properties of the \l Text element, which
+is probably not what was intended. This code can be corrected, by replacing \c {Binding 2}
+with this explicit element reference \c {root.ListView.view.width}.
+
+\code
+import Qt 4.6
+
+ListView {
+ delegate: Rectangle {
+ id: root
+ width: ListView.view.width // Binding 1
+ Text {
+ text: contactName
+ width: ListView.view.width // Binding 2
+ }
+ }
+}
+\endcode
+
+\e TODO
+
+\list
+\o scope object for PropertyChanges
+\endlist
+
+\section2 Root Object
+
+Properties and methods on the local scope component's root object appear in the scope chain
+immediately after the \l {Scope Object}. If the scope object and root object are the same,
+this step has no effect.
+
+This example uses the root object to easily propagate data throughout the component.
+
+\code
+Item {
+ property string description
+ property int fontSize
+
+ Text {
+ text: description
+ font.pixelSize: fontSize
+ }
+}
+\endcode
+
+\section1 QML Component chain
+
+When a QML component is instantiated it is given a parent component instance. The parent
+component instance is immutable - it is not affected, for example, by changes in the instance's
+visual parent (in the case of visual elements). Should name resolution fail within the
+\l {QML Local Scope}, this parent chain is searched.
+
+For each component instance in the chain, the following are examined:
+
+\list 1
+\o IDs
+\o Script Methods
+\o Root Object
+\endlist
+
+This list is a sub-set of that in the \l {QML Local Scope}.
+
+A sub-component's parent component instance is set to the component that created it.
+In the following example, the two \c Button instances have the
+\c main.qml instance as their parent component instance. If the \c Button type was used from
+within another QML file, it may have a difference parent component instance, and consequently
+the \c buttonClicked() method may resolve differently.
+
+\table
+\row
+\o
+\code
+// main.qml
+Item {
+ function buttonClicked(var data) {
+ print(data + " clicked");
+ }
+
+ Button { text: "Button1" }
+ Button { text: "Button2" }
+}
+\endcode
+\o
+\code
+// Button.qml
+Rectangle {
+ id: root
+ property string text
+ width: 80
+ height: 30
+ Text {
+ anchors.centerIn: parent
+ text: root.text
+ }
+ MouseRegion {
+ anchors.fill: parent
+ onClicked: buttonClicked(text)
+ }
+}
+\endcode
+\endtable
+
+The code above discourages the re-use of the \c Button component, as it has a hard dependency
+on the environment in which it is used. Tightly coupling two types together like this should
+only be used when the components are within the same module, and the author controls the
+implementations of both.
+
+In the following example, the \l ListView sets the parent component instance of each of its
+delegates to its own component instance. In this way, the main component can easily pass data
+into the \l ListView delegates.
+
+\code
+Item {
+ property color delegateColor: "red"
+
+ ListView {
+ delegate: Component {
+ Rectangle {
+ color: delegateColor
+ }
+ }
+ }
+}
+\endcode
+
+\section1 QmlContext chain
+
+The \l QmlContext chain allows C++ applications to pass data into QML applications.
+\l QmlComponent object instances created from C++ are passed a \l QmlContext in which they
+are created. Variables defined in this context appear in the scope chain. Each QmlContext
+also defines a parent context. Variables in child QmlContext's shadow those in its parent.
+
+Consider the following QmlContext tree.
+
+\image qml-context-tree.png
+
+The value of \c background in \c {Context 1} would be used if it was instantiated in
+\c {Context 1}, where as the value of the \c background in the root context would be used if
+the component instance was instantiated in \c {Context 2}.
+
+\code
+import Qt 4.6
+
+Rectangle {
+ id: myRect
+ width: 100; height: 100
+ color: background
+}
+\endcode
+
+\section1 QML Global Object
+
+The \l {QML Global Object} contains all the properties of the JavaScript global object, plus some
+QML specific extensions.

+\title Tutorial 1 - Basic Types
+
+This first program is a very simple "Hello world" example that introduces some basic QML concepts.
+The picture below is a screenshot of this program.
+
+\image declarative-tutorial1.png
+
+Here is the QML code for the application:
+
+\snippet examples/declarative/tutorials/helloworld/tutorial1.qml 0
+
+\section1 Walkthrough
+
+\section2 Import
+
+First, we need to import the types that we need for this example. Most QML files will import the built-in QML
+types (like \l{Rectangle}, \l{Image}, ...) that come with Qt with:
+
+\snippet examples/declarative/tutorials/helloworld/tutorial1.qml 3
+
+\section2 Rectangle element
+
+\snippet examples/declarative/tutorials/helloworld/tutorial1.qml 1
+
+We declare a root element of type \l{Rectangle}. It is one of the basic building blocks you can use to create an application in QML.
+We give it an \c{id} to be able to refer to it later. In this case, we call it \e page.
+We also set the \c width, \c height and \c color properties.
+The \l{Rectangle} element contains many other properties (such as \c x and \c y), but these are left at their default values.
+
+\section2 Text element
+
+\snippet examples/declarative/tutorials/helloworld/tutorial1.qml 2
+
+We add a \l Text element as a child of our root element that will display the text 'Hello world!'.
+
+The \c y property is used to position the text vertically at 30 pixels from the top of its parent.
+
+The \c font.pointSize and \c font.bold properties are related to fonts and use the \l{Dot Properties}{dot notation}.
+
+The \c anchors.horizontalCenter property refers to the horizontal center of an element.
+In this case, we specify that our text element should be horizontally centered in the \e page element (see \l{anchor-layout}{Anchor-based Layout}).
+
+\section2 Viewing the example
+
+To view what you have created, run the qmlviewer (located in the \c bin directory) with your filename as the first argument.
+For example, to run the provided completed Tutorial 1 example from the install location, you would type:
+
+\code
+bin/qmlviewer $QTDIR/examples/declarative/tutorials/helloworld/tutorial1.qml

+\title Tutorial 2 - QML Component
+
+This chapter adds a color picker to change the color of the text.
+
+\image declarative-tutorial2.png
+
+Our color picker is made of six cells with different colors.
+To avoid writing the same code multiple times, we first create a new \c Cell component.
+A component provides a way of defining a new type that we can re-use in other QML files.
+A QML component is like a black-box and interacts with the outside world through properties, signals and slots and is generally
+defined in its own QML file (for more details, see \l {Defining new Components}).
+The component's filename must always start with a capital letter.
+
+Here is the QML code for \c Cell.qml:
+
+\snippet examples/declarative/tutorials/helloworld/Cell.qml 0
+
+\section1 Walkthrough
+
+\section2 The Cell Component
+
+\snippet examples/declarative/tutorials/helloworld/Cell.qml 1
+
+The root element of our component is an \l Item with the \c id \e container.
+An \l Item is the most basic visual element in QML and is often used as a container for other elements.
+
+\snippet examples/declarative/tutorials/helloworld/Cell.qml 4
+
+We declare a \c color property. This property is accessible from \e outside our component, this allows us
+to instantiate the cells with different colors.
+This property is just an alias to an existing property - the color of the rectangle that compose the cell (see \l{intro-properties}{Properties}).
+
+\snippet examples/declarative/tutorials/helloworld/Cell.qml 5
+
+We want our component to also have a signal that we call \e clicked with a \e color parameter.
+We will use this signal to change the color of the text in the main QML file later.
+
+\snippet examples/declarative/tutorials/helloworld/Cell.qml 2
+
+Our cell component is basically a colored rectangle with the \c id \e rectangle.
+
+The \c anchors.fill property is a convenient way to set the size of an element.
+In this case the rectangle will have the same size as its parent (see \l{anchor-layout}{Anchor-based Layout}).
+
+\snippet examples/declarative/tutorials/helloworld/Cell.qml 3
+
+In order to change the color of the text when clicking on a cell, we create a \l MouseRegion element with
+the same size as its parent.
+
+A \l MouseRegion defines a signal called \e clicked.
+When this signal is triggered we want to emit our own \e clicked signal with the color as parameter.
+
+\section2 The main QML file
+
+In our main QML file, we use our \c Cell component to create the color picker:
+
+\snippet examples/declarative/tutorials/helloworld/tutorial2.qml 0
+
+We create the color picker by putting 6 cells with different colors in a grid.
+
+\snippet examples/declarative/tutorials/helloworld/tutorial2.qml 1
+
+When the \e clicked signal of our cell is triggered, we want to set the color of the text to the color passed as a parameter.
+We can react to any signal of our component through a property of the name \e 'onSignalName' (see \l{Signal Handlers}).

+\title Tutorial 3 - States and Transitions
+
+In this chapter, we make this example a little bit more dynamic by introducing states and transitions.
+
+We want our text to move to the bottom of the screen, rotate and become red when clicked.
+
+\image declarative-tutorial3_animation.gif
+
+Here is the QML code:
+
+\snippet examples/declarative/tutorials/helloworld/tutorial3.qml 0
+
+\section1 Walkthrough
+
+\snippet examples/declarative/tutorials/helloworld/tutorial3.qml 2
+
+First, we create a new \e down state for our text element.
+This state will be activated when the \l MouseRegion is pressed, and deactivated when it is released.
+
+The \e down state includes a set of property changes from our implicit \e {default state}
+(the items as they were initially defined in the QML).
+Specifically, we set the \c y property of the text to \c 160, the rotation to \c 180 and the \c color to red.
+
+\snippet examples/declarative/tutorials/helloworld/tutorial3.qml 3
+
+Because we don't want the text to appear at the bottom instantly but rather move smoothly,
+we add a transition between our two states.
+
+\c from and \c to define the states between which the transition will run.
+In this case, we want a transition from the default state to our \e down state.
+
+Because we want the same transition to be run in reverse when changing back from the \e down state to the default state,
+we set \c reversible to \c true.
+This is equivalent to writing the two transitions separately.
+
+The \l ParallelAnimation element makes sure that the two types of animations (number and color) start at the same time.
+We could also run them one after the other by using \l SequentialAnimation instead.
+
+For more details on states and transitions, see \l {QML States}.

+The SameGame example can interface with a simple PHP script to store XML high score data on a remote server. We do not have a publically accessible server available for this use, but if you have access to a PHP capable webserver you can copy the files (score_data.xml, score.php, score_style.xsl) to it and alter the highscore_server variable at the top of the samegame.js file to point to it.

+Flickable: pageHeight -> visibleArea.heightRatio
+WebView: idealWidth -> preferredWidth
+WebView: idealHeight -> preferredHeight
+WebView: status -> statusText
+WebView: mouseX -> clickX (parameter to onDoubleClick)
+WebView: mouseY -> clickY (parameter to onDoubleClick)
+WebView: cacheSize -> pixelCacheSize
+Repeater: component -> delegate
+Repeater: dataSource -> model

+Flickable: removed "dragMode" property
+ComponentInstance: removed. Replaced by Loader.sourceComponent
+ListView: removed currentItemMode. Replaced by highligh range.
+ListView: removed snapPos.
+Particles: removed streamIn. Replaced by emissionRate
+
+Other Changes:
+ids must be lowercase: Text { id: foo }, not Text { id: Foo }
+Drag: axis becomes an enum with values "XAxis", "YAxis", "XandYAxis"
+Image: scaleGrid property removed. New item called BorderImage instead.
+KeyActions: changed to a Keys attached property on any item.
+KeyProxy: changed to a Keys.forwardTo property on any item.
+Script: now an intrinsic type in the language
+ - cannot be assigned to properties
+ - good: Item { Script { ... } }
+ - bad: Item { resources: Script { ... } }
+Script: delay-loaded of the QML file until their source has been loaded (this only effects QML files loaded across the network.)
+Scope: declared properties shadow a property of the same name (was previously the reverse)
+ScriptAction and StateChangeScript: the script property now takes script rather than a string containing script (script: doSomething() rather than script: "doSomething()")
+QmlGraphicsItem::transformOrigin default changed from TopLeft to Center
+Animations used as PropertySourceValues are set to 'running: true' as default

+ \class QPacketProtocol
+ \internal
+
+ \brief The QPacketProtocol class encapsulates communicating discrete packets
+ across fragmented IO channels, such as TCP sockets.
+
+ QPacketProtocol makes it simple to send arbitrary sized data "packets" across
+ fragmented transports such as TCP and UDP.
+
+ As transmission boundaries are not respected, sending packets over protocols
+ like TCP frequently involves "stitching" them back together at the receiver.
+ QPacketProtocol makes this easier by performing this task for you. Packet
+ data sent using QPacketProtocol is prepended with a 4-byte size header
+ allowing the receiving QPacketProtocol to buffer the packet internally until
+ it has all been received. QPacketProtocol does not perform any sanity
+ checking on the size or on the data, so this class should only be used in
+ prototyping or trusted situations where DOS attacks are unlikely.
+
+ QPacketProtocol does not perform any communications itself. Instead it can
+ operate on any QIODevice that supports the QIODevice::readyRead() signal. A
+ logical "packet" is encapsulated by the companion QPacket class. The
+ following example shows two ways to send data using QPacketProtocol. The
+ transmitted data is equivalent in both.
+
+ \code
+ QTcpSocket socket;
+ // ... connect socket ...
+
+ QPacketProtocol protocol(&socket);
+
+ // Send packet the quick way
+ protocol.send() << "Hello world" << 123;
+
+ // Send packet the longer way
+ QPacket packet;
+ packet << "Hello world" << 123;
+ protocol.send(packet);
+ \endcode
+
+ Likewise, the following shows how to read data from QPacketProtocol, assuming
+ that the QPacketProtocol::readyRead() signal has been emitted.
+
+ \code
+ // ... QPacketProtocol::readyRead() is emitted ...
+
+ int a;
+ QByteArray b;
+
+ // Receive packet the quick way
+ protocol.read() >> a >> b;
+
+ // Receive packet the longer way
+ QPacket packet = protocol.read();
+ p >> a >> b;
+ \endcode

+ \qmlclass GraphicsObjectContainer QmlGraphicsGraphicsObjectContainer
+ \brief The GraphicsObjectContainer element allows you to add QGraphicsObjects into Fluid UI elements.
+
+ While any QObject based class can be exposed to QML, QmlGraphicsItem
+ provides a lot of important functionality, including anchors and proper
+ management of child items. GraphicsObjectContainer helps provide these
+ functions to other QGraphicsObjects, so that they can be used unaltered in
+ a QML scene. QGraphicsObjects, which are not QmlGraphicsItems, and which are
+ placed in a QML scene outside of a GraphicsObjectContainer, will not appear
+ on screen at all.
+
+ A GraphicsObjectContainer can have one element inside it, and it must be a
+ QGraphicsObject or subclass which has been exposed to the QML engine.
+ The graphics object inside the GraphicsObjectContainer can then be used
+ like any other item in QML with the exception of not being reparentable
+ and not having the standard properties of QML items (such as anchors).
+
+ As the contained object is positioned relative to the container, anchors
+ affecting the container item will affect the onscreen position of the
+ contained item. If synchronizedResizing is set to true, then anchors
+ affecting the container item's size will also affect the contained item's
+ size.
+
+ Example:
+ \code
+ import Qt 4.6
+ import MyApp 2.1 as Widgets
+ Rectangle{
+ id: rect
+ property alias widgetPropertyThree: widget.myThirdProperty;
+ GraphicsObjectContainer{
+ synchronizedResizing: true
+ anchors.margins: 10
+ anchors.fill: parent
+ Widgets.MyWidget{
+ myProperty: "A Value"
+ myOtherProperty: rect.color
+ }
+ }
+ }

+ \qmlclass GridView QmlGraphicsGridView
+ \inherits Flickable
+ \brief The GridView item provides a grid view of items provided by a model.
+
+ The model is typically provided by a QAbstractListModel "C++ model object",
+ but can also be created directly in QML.
+
+ The items are laid out top to bottom (vertically) or left to right (horizontally)
+ and may be flicked to scroll.
+
+ The below example creates a very simple grid, using a QML model.
+
+ \image gridview.png
+
+ \snippet doc/src/snippets/declarative/gridview/gridview.qml 3
+
+ The model is defined as a ListModel using QML:
+ \quotefile doc/src/snippets/declarative/gridview/dummydata/ContactModel.qml
+
+ In this case ListModel is a handy way for us to test our UI. In practice
+ the model would be implemented in C++, or perhaps via a SQL data source.

+ between focussed items. The KeyNavigation property provides a
+ convenient way of specifying which item will gain focus
+ when an arrow key is pressed. The following example provides
+ key navigation for a 2x2 grid of items.
+
+ \code
+ Grid {
+ columns: 2
+ width: 100; height: 100
+ Rectangle {
+ id: item1
+ focus: true
+ width: 50; height: 50
+ color: focus ? "red" : "lightgray"
+ KeyNavigation.right: item2
+ KeyNavigation.down: item3
+ }
+ Rectangle {
+ id: item2
+ width: 50; height: 50
+ color: focus ? "red" : "lightgray"
+ KeyNavigation.left: item1
+ KeyNavigation.down: item4
+ }
+ Rectangle {
+ id: item3
+ width: 50; height: 50
+ color: focus ? "red" : "lightgray"
+ KeyNavigation.right: item4
+ KeyNavigation.up: item1
+ }
+ Rectangle {
+ id: item4
+ width: 50; height: 50
+ color: focus ? "red" : "lightgray"
+ KeyNavigation.left: item3
+ KeyNavigation.up: item2
+ }
+ }
+ \endcode
+
+ KeyNavigation receives key events after the item it is attached to.
+ If the item accepts an arrow key event, the KeyNavigation
+ attached property will not receive an event for that key.
+
+ If an item has been set for a direction and the KeyNavigation
+ attached property receives the corresponding
+ key press and release events, the events will be accepted by
+ KeyNaviagtion and will not propagate any further.

+ \qmlclass Item QmlGraphicsItem
+ \brief The Item is the most basic of all visual items in QML.
+
+ All visual items in Qt Declarative inherit from Item. Although Item
+ has no visual appearance, it defines all the properties that are
+ common across visual items - such as the x and y position, the
+ width and height, \l {anchor-layout}{anchoring} and key handling.
+
+ Item is also useful for grouping items together.
+
+ \qml
+ Item {
+ Image {
+ source: "tile.png"
+ }
+ Image {
+ x: 80
+ width: 100
+ height: 100
+ source: "tile.png"
+ }
+ Image {
+ x: 190
+ width: 100
+ height: 100
+ fillMode: Image.Tile
+ source: "tile.png"
+ }
+ }
+ \endqml
+
+ \section1 Identity
+
+ Each item has an "id" - the identifier of the Item.
+
+ The identifier can be used in bindings and other expressions to
+ refer to the item. For example:
+
+ \qml
+ Text { id: myText; ... }
+ Text { text: myText.text }
+ \endqml
+
+ The identifier is available throughout to the \l {components}{component}
+ where it is declared. The identifier must be unique in the component.
+
+ The id should not be thought of as a "property" - it makes no sense
+ to write \c myText.id, for example.
+
+ \section1 Key Handling
+
+ Key handling is available to all Item-based visual elements via the \l {Keys}{Keys}
+ attached property. The \e Keys attached property provides basic handlers such
+ as \l {Keys::onPressed}{onPressed} and \l {Keys::onReleased}{onReleased},
+ as well as handlers for specific keys, such as
+ \l {Keys::onCancelPressed}{onCancelPressed}. The example below
+ assigns \l {qmlfocus}{focus} to the item and handles
+ the Left key via the general \e onPressed handler and the Select key via the
+ onSelectPressed handler:
+
+ \qml
+ Item {
+ focus: true
+ Keys.onPressed: {
+ if (event.key == Qt.Key_Left) {
+ console.log("move left");
+ event.accepted = true;
+ }
+ }
+ Keys.onSelectPressed: console.log("Selected");
+ }
+ \endqml
+
+ See the \l {Keys}{Keys} attached property for detailed documentation.

+ \qmlclass ListView QmlGraphicsListView
+ \inherits Flickable
+ \brief The ListView item provides a list view of items provided by a model.
+
+ The model is typically provided by a QAbstractListModel "C++ model object",
+ but can also be created directly in QML. The items are laid out vertically
+ or horizontally and may be flicked to scroll.
+
+ The below example creates a very simple vertical list, using a QML model.
+ \image trivialListView.png
+
+ The user interface defines a delegate to display an item, a highlight,
+ and the ListView which uses the above.
+
+ \snippet doc/src/snippets/declarative/listview/listview.qml 3
+
+ The model is defined as a ListModel using QML:
+ \quotefile doc/src/snippets/declarative/listview/dummydata/ContactModel.qml
+
+ In this case ListModel is a handy way for us to test our UI. In practice
+ the model would be implemented in C++, or perhaps via a SQL data source.

+ These properties set the preferred range of the highlight (current item)

+ currently selected item to be in the middle of the list, then set the

+ the currently selected item will be the item at that spot. This also applies to
+ when the currently selected item changes - it will scroll to within the preferred
+ highlight range. Furthermore, the behaviour of the current item index will occur
+ whether or not a highlight exists.
+
+ If highlightRangeMode is set to \e ApplyRange the view will
+ attempt to maintain the highlight within the range, however
+ the highlight can move outside of the range at the ends of the list
+ or due to a mouse interaction.

+ If highlightRangeMode is set to \e StrictlyEnforceRange the highlight will never
+ move outside of the range. This means that the current item will change
+ if a keyboard or mouse action would cause the highlight to move
+ outside of the range.

+/*!
+ \qmlclass Loader QmlGraphicsLoader
+ \inherits Item
+
+ \brief The Loader item allows dynamically loading an Item-based
+ subtree from a QML URL or Component.
+
+ Loader instantiates an item from a component. The component to
+ instantiate may be specified directly by the \c sourceComponent
+ property, or loaded from a URL via the \c source property.
+
+ It is also an effective means of delaying the creation of a component
+ until it is required:
+ \code
+ Loader { id: pageLoader }
+ Rectangle {
+ MouseRegion { anchors.fill: parent; onClicked: pageLoader.source = "Page1.qml" }
+ }
+ \endcode
+
+ If the Loader source is changed, any previous items instantiated
+ will be destroyed. Setting \c source to an empty string
+ will destroy the currently instantiated items, freeing resources
+ and leaving the Loader empty. For example:
+
+ \code
+ pageLoader.source = ""
+ \endcode
+
+ unloads "Page1.qml" and frees resources consumed by it.

+ Below we have the previous
+ example extended so as to give a different color when you right click.
+ \snippet doc/src/snippets/declarative/mouseregion.qml 1

+ You also need to set a PositionerType, to declare whether you are positioning the x, y or both
+ for the child items. Depending on the chosen type, only x or y changes will be applied.

+ \qmlclass Grid QmlGraphicsGrid
+ \brief The Grid item positions its children in a grid.
+ \inherits Item
+
+ The Grid item positions its child items so that they are
+ aligned in a grid and are not overlapping. Spacing can be added
+ between the items. It also provides for transitions to be set when items are
+ added, moved, or removed in the positioner. Adding and removing apply
+ both to items which are deleted or have their position in the
+ document changed so as to no longer be children of the positioner, as
+ well as to items which have their opacity set to or from zero so
+ as to appear or disappear.
+
+ The Grid defaults to using four columns, and as many rows as
+ are necessary to fit all the child items. The number of rows
+ and/or the number of columns can be constrained by setting the rows
+ or columns properties. The grid positioner calculates a grid with
+ rectangular cells of sufficient size to hold all items, and then
+ places the items in the cells, going across then down, and
+ positioning each item at the (0,0) corner of the cell. The below
+ example demonstrates this.
+
+ \table
+ \row
+ \o \image gridLayout_example.png
+ \o
+ \qml
+Grid {
+ columns: 3
+ spacing: 2
+ Rectangle { color: "red"; width: 50; height: 50 }
+ Rectangle { color: "green"; width: 20; height: 50 }
+ Rectangle { color: "blue"; width: 50; height: 20 }
+ Rectangle { color: "cyan"; width: 50; height: 50 }
+ Rectangle { color: "magenta"; width: 10; height: 10 }
+}
+ \endqml
+ \endtable
+
+ Note that the positioner assumes that the x and y positions of its children
+ will not change. If you manually change the x or y properties in script, bind
+ the x or y properties, or use anchors on a child of a positioner, then the
+ positioner may exhibit strange behaviour.

+ similar items. For each entry in the model, an item is instantiated
+ in a context seeded with data from the model. If the repeater will
+ be instantiating a large number of instances, it may be more efficient to
+ use one of Qt Declarative's \l {xmlViews}{view items}.
+
+ The model may be either an object list, a string list, a number or a Qt model.
+ In each case, the data element and the index is exposed to each instantiated
+ component.
+
+ The index is always exposed as an accessible \c index property.
+ In the case of an object or string list, the data element (of type string
+ or object) is available as the \c modelData property. In the case of a Qt model,
+ all roles are available as named properties just like in the view classes. The
+ following example shows how to use the index property inside the instantiated
+ items.
+
+ \snippet doc/src/snippets/declarative/repeater-index.qml 0
+
+ \image repeater-index.png
+
+ Items instantiated by the Repeater are inserted, in order, as
+ children of the Repeater's parent. The insertion starts immediately after
+ the repeater's position in its parent stacking list. This is to allow
+ you to use a Repeater inside a layout. The following QML example shows how
+ the instantiated items would visually appear stacked between the red and
+ blue rectangles.
+
+ \snippet doc/src/snippets/declarative/repeater.qml 0
+
+ \image repeater.png
+
+ The repeater instance continues to own all items it instantiates, even
+ if they are otherwise manipulated. It is illegal to manually remove an item
+ created by the Repeater.
