To assign the transition to an object, bind it to the +\c transitions property. -The PropertyAnimation is triggered when the MouseArea is clicked, animating the -\c x and \c y properties to a value of 50 over 1000 milliseconds. Since the -animation is not bound to a particular object or property, it must define the -\l {PropertyAnimation::}{target} and \l {PropertyAnimation::}{property} (or \l -{PropertyAnimation::}{targets} and \l{PropertyAnimation::}{properties}) values. -The \l {PropertyAnimation::}{to} property is also required to specify the new -\c x and \c y values. +A button might have two states, the \c pressed state when the user clicks on the +button and a \c released state when the user releases the button.

Unlike a -property definition, which allocates a new, unique storage space for the -property, a property alias connects the newly declared property (called the -aliasing property) as a direct reference 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 an ordinary 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 compulsory 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. - -For example, below is a \c Button.qml component with a \c buttonText aliased property which is -connected to the child Text object's \c text property: - -\snippet doc/src/snippets/declarative/qml-extending-types/properties/alias.qml 0 - -The following code would create a \c Button with a defined text string for the -child \l Text object: - -\qml -Button { buttonText: "This is a button" } -\endqml - -Here, modifying \c buttonText directly modifies the \c textItem.text value; it does not -change some other value that then updates \c textItem.text. - -In this case, the use of aliased properties is essential. If \c buttonText was not an alias, -changing its value would not actually change the displayed text at all, as -\l {Property Binding}{property bindings} are not bi-directional: the \c buttonText value would -change when \c textItem.text changes, but not the other way around. - -Aliased properties are also useful for allowing external objects to directly modify and -access child objects in a component. For example, here is a modified version of the \c ImageViewer -component shown \l {Adding Properties}{earlier} on this page. The \c currentImage property has -been changed to an alias to the child \l Image object: - -\table -\row -\o \snippet doc/src/snippets/declarative/qml-extending-types/properties/alias/ImageViewer.qml 0 -\o \snippet doc/src/snippets/declarative/qml-extending-types/properties/alias/application.qml 0 -\endtable - -Instead of being limited to setting the \l Image source, \c application.qml can now directly -access and modify the child \l Image object and its properties. - -Obviously, exposing child objects in this manner should be done with care, as it allows external -objects to modify them freely. However, this use of aliased properties can be quite useful in -particular situations, such as for the \l {declarative/ui-components/tabwidget}{TabWidget} -example, where new tab items are actually parented to a child object that displays the current tab. - - -\section3 Considerations for property aliases - -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 during creation. For example, this will not work: - -\code - // Does NOT work - property alias buttonText: textItem.text - buttonText: "Some text" // buttonText is not yet defined when this value is set -\endcode - -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 buttonText: textItem.text - property alias buttonText2: root.buttonText -\endcode - -At the time the component is created, the \c buttonText value has not yet been assigned, -so \c root.buttonText would refer to an undefined value. (From outside the component, -however, aliasing properties appear as regular Qt properties and consequently can be -used in alias references.) - -It is possible for an aliased property to have the same name as an existing property. For example, -the following component has a \c color alias property, named the same as the built-in -\l {Rectangle::color} property: - -\snippet doc/src/snippets/declarative/qml-extending-types/properties/alias-override.qml 0 - -Any objects that use this component and refer to its \c color property will be -referring to the alias rather than the ordinary \l {Rectangle::color} property. Internally, -however, the rectangle can correctly set this property to "red" and refer to the actual defined -property rather than the alias. - - -\section1 Adding Methods - -A QML component can define methods of JavaScript code. These methods can be invoked -either internally or by other objects. - -The syntax for defining a method is: - -\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.) - -Unlike \l{Adding Signals}{signals}, method parameter types do not have to be declared as they -default to the \c variant type. The body of the method is written in JavaScript and may access -the parameters by name. - -Here is an example of a component with a \c say() method that accepts a single \c text argument: - -\snippet doc/src/snippets/declarative/qml-extending-types/methods/app.qml 0 - -A method can be connected to a signal so that it is automatically invoked whenever the signal -is emitted. See \l {Connecting signals to methods and other signals} below. - -Also see \l {Integrating JavaScript} for more information on using JavaScript with QML. - - -\section1 Adding Signals - -Signals provide a way to notify other objects when an event has occurred. For example, the MouseArea -\c clicked signal notifies other objects that the mouse has been clicked within the area. - -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.) - -Here are three examples of signal declarations: - -\code -Item { - signal clicked - signal hovered() - signal performAction(string action, variant actionArgument) -} -\endcode - -If the signal has no parameters, the "()" brackets are optional. If parameters are used, the -parameter types must be declared, as for the \c string and \c variant arguments for the \c -performAction signal above; the allowed parameter types are the same as those listed in the \l -{Adding Properties} section on this page. - -Adding a signal to an item automatically adds a \l {Signal Handlers}{signal handler} as well. -The signal hander is named \c on<SignalName>, with the first letter of the signal being upper -cased. The above example item would now have the following signal handlers: - -\list -\o onClicked -\o onHovered -\o onPerformAction -\endlist - -To emit a signal, simply invoke it in the same way as a method. Below left, when the \l MouseArea is -clicked, it emits the parent \c buttonClicked signal by invoking \c rect.buttonClicked().

When a signal is connected to a method, the method is automatically invoked -whenever the signal is emitted. (In Qt terminology, the method is a \e slot that is connected -to the \e signal; all methods defined in QML are created as Qt slots.) This enables a signal -to be received by a method instead of a \l {Signal Handlers}{signal handler}. - -For example, the \c application.qml above could be rewritten as: - -\snippet doc/src/snippets/declarative/qml-extending-types/signals/connectslots.qml 0 - -The \c myMethod() method will be called whenever the \c buttonClicked signal is received. - -In many cases it is sufficient to receive signals through signal handlers rather than using -the \c connect() function; the above example does not provide any improvements over using a -simple \c onButtonClicked handler. However, if you are \l{Dynamic Object Management in QML}{creating objects dynamically}, -or \l {Integrating JavaScript}{integrating JavaScript code}, then you will find the -\c connect() method useful. For example, the component below creates three \c Button -objects dynamically, and connects the \c buttonClicked signal of each object to the -\c myMethod() function: - -\snippet doc/src/snippets/declarative/qml-extending-types/signals/connectdynamic.qml 0 - -In the same way, you could connect a signal to methods defined in a dynamically -created object, or \l {Receiving QML Signals in JavaScript}{connect a signal to a JavaScript method}. - -There is also a corresponding \c disconnect() method for removing connected signals.

For example: - -\qml -Rectangle { - // ... - states: [ - State { - name: "moved" - PropertyChanges { target: myRect; x: 50; y: 50; color: "blue" } - PropertyChanges { target: someOtherItem; width: 1000 } - } - ] -} -\endqml - -As a convenience, if an item only has one state, its \l {Item::}{states} -property can be defined as a single \l State, without the square-brace list -syntax: - -\snippet doc/src/snippets/declarative/propertyanimation.qml single state - -A \l State is not limited to performing modifications on property values.

This can be achieved by using the \l {State::}{when} property, -like this: - -\qml -Rectangle { - // ... - - MouseArea { - id: mouseArea - anchors.fill: parent - } - - states: State { - name: "moved" - when: mouseArea.pressed - // ... - } -} -\endqml - -The \l {State::}{when} property is set to an expression that evaluates to -\c true when the item should be set to that state. When the mouse is pressed, -the state is changed to \e moved. When it is released, the item reverts to its -\e default state, which defines all of the item's original property values. - -Alternatively, an item can be explicitly set to its default state by setting its -\l {Item::}{state} property to an empty string (""). For example, instead of -using the \l {State::}{when} property, the above code could be changed to: - -\qml -Rectangle { - // ... - - MouseArea { - anchors.fill: parent - onPressed: myRect.state = 'moved'; - onReleased: myRect.state = ''; - } - - states: State { - name: "moved" - // ... - } -} -\endqml - -Obviously it makes sense to use the \l {State::}{when} property when possible -as it provides a simpler (and a better, more declarative) solution than -assigning the state from signal handlers. - - -\section1 Animating State Changes +Every \l Item based component has a \c state property and a \e{default state}. +The default state is the empty string (\c{""}) and contains all of an item's +initial property values.

Its commands, more correctly \e elements, -leverage the power and efficiency of the Qt libraries to make easy to use -commands that perform intuitive functions. Draw a rectangle, display an image at -a position and so on. Behind these elements are complex C++ libraries that -efficiently perform the action. As with any graphical application, always -consider that this ability to easily build graphically rich applications means -that some care may be needed to prevent performance problems. - -The language also allows more flexibility of these commands by using -Javascript rather than C++ to add new layers of logic to your application. -Javascript is easier to learn than C++ and can be embedded into the QML -files or imported from a separate file. - -\bold{In QML the types of various 'objects' are referred to as \l {QML -Elements}{elements}}. - -An element usually has various \e properties that help define the element. For -example, if we created an element called Circle then the radius of the circle -would be a property. - - -\section1 A First Look - -The basic syntax of an \l{QML Elements}{element} is - -\qml -SomeElement { - id: myObject - // ... some other things here ... -} -\endqml - -Here we are defining a new object. We specify its 'type' first as SomeElement. -Then within matching braces { ... } we specify the various parts of our -element. - -The \c id is a unique identifier for the element, it must start with a lower -case letter and only contain letters, numbers and underscores. It is this -particular object's name. If this SomeElement \l {QML Elements}{element} was -a Rectangle instead and it was one of many then the \e optional unique id -would allow us to manipulate each element individually. - -Each visual element is ultimately based on, or inherits from, an element -called \l Item. \l Item has certain properties and actions that may be -useful. The properties have default values so you need only specify the -ones you will need. - -Take a simple element such as a \l Rectangle. It has an \c id, we will call -it \e myRectangle, it has a \c width and a \c height. Imagine that we -want a rectangle that is 500 pixels by 400 pixels in the x and y directions -(horizontal by vertical). - -We can implement this \l Rectangle with these properties this way - -\snippet doc/src/snippets/declarative/qml-intro/rectangle.qml document - -This is a valid QML script. To run it, copy it and save it to a file, say -myexample.qml, and on the command line run the following command: - -\code -qmlviewer myexample.qml -\endcode - -On Mac OS X, open the "QMLViewer" application instead and open the -\c myexample.qml file, or run it from the command line: - -\code -QMLViewer.app/Contents/MacOS/QMLViewer myexample.qml -\endcode - -It will create a very boring rectangle in its own window. - - -\section1 Hello World! - -We can now add some color and text to make a Hello World QML program. - -\l Rectangle has the property \l{Rectangle::color}{color} to produce a -background color. - -Text is handled by a different element called \l Text. We need to create a -\l Text object inside the \l Rectangle and set its \l{Text::}{text} -property to "Hello World!". So to set the text to "Hello world" and the -background colour to light gray, - -\snippet doc/src/snippets/declarative/qml-intro/hello-world1.qml document - - -\section1 Hello World Again - -From now on we will not always show the import statement for Qt but it -should still be there when you create your QML scripts. - -To make our Hello World example a little nicer set the position of the text -to be at pixel position x = 100, y = 100 within the displayed window. This -position belongs to the \l Text element so we set the position inside its -definition. Note that we separate different QML statements on the same line -with a semi-colon, or we could have simply put each statement on a new line - -\snippet doc/src/snippets/declarative/qml-intro/hello-world2.qml updated text - -Not only did we reposition the text, but the text was altered by adding -HTML tags to change the font size. The text color was also changed from the -default black to dark green by using a standard string for the color's SVG -name. - -We could also have used a hexadecimal string for the RGB (red-green-blue, as -#rrggbb) values of the color similar to the method used in HTML. For -example, mostly blue with a green tint, - -\snippet doc/src/snippets/declarative/qml-intro/hello-world3.qml updated text - -All of these changes occurred within the \l Text object which is the scope -of these property changes. - -Other objects may use the information but it belongs to the element where -the property has been defined. - - -\section1 Images - -To add an image to our little application we use the \l Image element. An -\l Image uses a path to an image file, and has properties to control -the aspect ratio, the image size, to tile the area amongst others. The -source of the image, the path to the file, is a URL. Therefore the file can -be local: \e {mydir/myimage1.png}. Or it can be remote: -\e {"http://www.example.com/images/myimage1.png"}. - -\snippet doc/src/snippets/declarative/qml-intro/hello-world4.qml added an image - -This displays the image, as we would expect, at the top left of the window. -The position of the default x = 0, y = 0 coordinate. The example here uses -a PNG file, but it could have been one of various supported formats, -including JPG and GIF. - -Let us reposition the image and enlarge it. Place it at the same 'x' offset -as the "Hello world again" text, but put it another 50 pixels below the -text, also make it 150 by 150 pixels in size, - -\snippet doc/src/snippets/declarative/qml-intro/hello-world5.qml positioning the image - -Adding the Hello World example, with the text and the image example we can -write a simple piece of QML that starts to look a bit better. - -\snippet doc/src/snippets/declarative/qml-intro/hello-world5.qml document - -The result is still quite simple - -\image qml-intro-helloa.png - - -\section1 Anchors: Aligning Elements - -Using absolute positioning, such as saying x = 100 and y = 150, works well -until the user or developer stretches or increases the size of the window. -Then the positions need to be recalculated. What would be nice would be a -relative means of positioning of objects in a window or rectangle. For -example, we want to place an image at the bottom of a rectangle, we would -like to specify the image's location as the 'bottom of the window', not a -specific coordinate. We can do this with the anchors property, which -objects inherit from Item. - -The anchors property is really a property group. It is a collection of -related properties. It has properties within it which can be used by means -of the dot notation. - -The dot notation uses object \c{id}s and property names to use a particular -object or property. Say I have a rectangle r1, which contains a rectangle -r2, which contains an Item item1, which has an 'x' property I want to -change. I just use the dot notation to identify it: r1.r2.item1.x - -If we want to position an image at the bottom of the rectangle it is -inside. I have to specify that the bottom of the image is also at the -bottom of the rectangle - -\snippet doc/src/snippets/declarative/qml-intro/anchors1.qml document - -This places the logo at the bottom left of the window. - -\image qml-intro-anchors1.png "A simple anchor" - -We would like it centered and not touching the bottom of the window, for -aesthetic reasons. For the centering we use the horizontalCenter property, -and to prevent the touching of the image to the bottom of the rectangle, -the bottomMargin property is used. So the new actions for the script are - - \list - \o set the bottom of the image (anchors.bottom) to be the bottom of the window - \o move the image to be in the horizontal center of the window - \o set a margin of 10 pixels so that the image does not touch the bottom window border - \endlist - -Encoded into QML the script becomes - -\snippet doc/src/snippets/declarative/qml-intro/anchors2.qml document - -Run this and resize the window. You will see that now the position of the -image adjusts during the resize. - -\image qml-intro-anchors2.png "Image Centered at the Bottom" - -You can also add another object say a block of descriptive text and place -it above or below the image or to the side. This code places some text just -above the image - -\snippet doc/src/snippets/declarative/qml-intro/anchors3.qml adding some text - -\image qml-intro-anchors3.png - -\note \e anchors is a property group, to be used within the object. When -referencing these properties from another object we use the property -directly, instead of saying: - -\qml -Item { - anchors.bottom: myRectangle.anchors.top // Wrong -} -\endqml - -we use - -\qml -Item { - anchors.bottom: myRectangle.top // Correct -} -\endqml - - -\section1 Transformations - -We can transform a graphical object to get additional effects. Rotate a -piece of text by 180 degrees to display upside-down text. Rotate an image -by 90 degrees to lay it on its side. These transformations require -additional information. - -For rotation, the additional information includes: the origin relative to -the object being rotated, the axis of rotation, and the angle in degrees to -rotate the image through in a clockwise direction. The axis does not have -to be the z-axis, the line between your eyes and the image, it could be -along the vertical y-axis or the horizontal x-axis. We have three -dimensions to play with. For simplicity in this example we will rotate -about the z-axis by 90 degrees in a negative direction, anti-clockwise. - -Rotation of text was also suggested. It could also be useful to scale the -text. We can do both. The \l {Item::transform}{transform} property is a -\e list of \l Transform elements, so using the list syntax -\c{myList: [ listElement1, listElement2, ... } ]} -we can produce a list of transformations. - -The text will be rotated by 45 degrees anti-clockwise and scaled -vertically by a factor of 1.5 and by 1.2 horizontally. - -Using the example above as the basis for this we have, - -\snippet doc/src/snippets/declarative/qml-intro/transformations1.qml document - -The code block in \c image1 starting with \c transform specifies that the -\l {Item::transform}{transform} property will be a Rotation through -90 -degrees, which is anti-clockwise, about the z-axis running through the -center of the image at (75,75), since the image is 150 x 150 pixels. - -The other transformation available is \l Translate. This produces a change -in position of the item. - -\note In a list of transformations the order of the transformations is -important. In the above example try swapping around the Scale transform with -the Rotation transform, remember to remove or add the comma. The results are -acceptable for our little test but not the same. - - -\section1 Animations - -Animation in QML is done by animating properties of objects. Properties -that are numbers, colors, Rectangles, points and directions. In QML these -are \l {QML Basic Types} named as real, int, color, rect, point, size, and -vector3d. There are a number of different ways to do animation. Here we -will look at a few of them. - -\section2 Number Animation - -Previously we have used a rotation transformation to change the orientation -of an image. We could easily animate this rotation so that instead of a -straight rotation counter-clockwise of 90 degrees we could rotate the image -through a full 360 degrees in an animation. The axis of rotation wont -change, the position of the center of the image will not change, only the -angle will change. Therefore, a NumberAnimation of a rotation's angle should -be enough for the task. If we wish for a simple rotation about the center -of the image then we can use the \c rotation property that is inherited -from \l Item. The rotation property is a real number that specifies the -angle in a clockwise direction for the rotation of the object. Here is the -code for our animated rotating image. - -\snippet doc/src/snippets/declarative/qml-intro/number-animation1.qml document - -The \c {transformOrigin: Item.Center} is redundant since this is the default -axis of rotation anyway. But if you change \c Center to \c BottomRight you -will see an interesting variation. - -Also if instead the \l Rotation transformation had been used then we would have -more control over the various parameters. We could vary the axis, to be not -just a different offset from the z-axis but along the y-axis, x-axis or -combination. For example, if the task had been to animate the rotation -about the y-axis passing through the center of the image then the following -code would do it. - -\snippet doc/src/snippets/declarative/qml-intro/number-animation2.qml document - -Here there is a rectangle 600 by 400 pixels. Placed within that rectangle -is an image 100 by 100 pixels. It is rotated about the center of the image -about the y-axis so that it looks as if it is rotating about an invisible -vertical string holding it up. The time it takes to complete the rotation is 3 -seconds (3,000 milliseconds). The NumberAnimation is applied to the angle -taking it from 0 (no change) to 360 degrees, back where it started. -Strictly speaking it isn't necessary to go from 0 to 360 since the same -location is duplicated, but it makes it easier to read in this example and -it has no visible effect on the animation. The number of loops that the -animation will execute is set to \c {Animation.Infinite} which means that the -animation is in an endless loop. - -To see an interesting variation. Change the axis to \c {axis { x:1; y:1; z:1 -}}. This is a line coming from the center of the image downwards to the -right and out of the screen. Although the change is simple the rotation -seems complex. - -\section2 Sequential Animation - -For a more complex animation we will need two images. The first image will -be placed at the center of a window (Rectangle) and the second image will -be at the upper left of the window. The animation will move the second -image from the top left of the window to the bottom right. In doing so we -will be animating the position and the size of the image. - -First create two images - -\snippet doc/src/snippets/declarative/qml-intro/sequential-animation1.qml document - -We will add to 'image1' a SequentialAnimation from x = 20 to the target of -x = 450. The 'from' values will be used because we will be repeating the -animation, so the object needs to know where the original position is, both -x and y. The SequentialAnimation of x will set it to repeat by indicating -that the number of animation loops is infinite, meaning that the 'loop' -counter will be set to a value Animation.Infinite that indicates an endless -cycle. Also there will be a NumberAnimation to vary the numeric property -between the x values and over a given duration. After the NumberAnimation -there will be a PauseAnimation that will pause the animation for 500 -milliseconds (half a second) simply for the visual effect. - -\snippet doc/src/snippets/declarative/qml-intro/sequential-animation2.qml adding a sequential animation - -A similar block of code is written for the animation of the 'y' value of -the position. - -We will also animate the scale of the object, so as it goes from top left -to bottom right of the window it will become smaller until about midway, -and then become larger. To complete the animation we will set the 'z' -values of the images. 'z' is the stacking order, the z-axis effectively -points out from the screen to your eyes with the default value of 'z' being -0. So if we set the Rectangle to have z with value zero, just to be sure, -and image1 to 1 and image2 to 2 then image2 will be in the foreground and -image1 in the background. When image1 passes image2 it will pass behind it. -The completed code looks like - -\snippet doc/src/snippets/declarative/qml-intro/sequential-animation3.qml document - -The \c {easing.type} has many options, expressed as a string. It specifies the -kind of equation that describes the acceleration of the property value, not -necessarily position, over time. - -For example, \e InOutQuad means that at the start and the end of the animation the -'velocity' is low but the acceleration or deceleration is high. Much like a car -accelerating from stop, and decelerating to stop at the end of a journey, -with the maximum speed being in the middle. Examine the \l {PropertyAnimation::easing.type} -{easing} documentation and the various graphs that show the effect. The horizontal -axis, 'progress', can be thought of as time. The vertical axis is the value -of the particular property. - -In discussing animation we need to describe three objects: State, MouseArea -and Signals. Although independent of the animation elements, animation -delivers some of the best examples that illustrate these new elements. - - - -\section2 Animation Summary - -\table - \header - \o Name - \o Description - \row - \o PropertyAnimation - \o a property value on a target object is varied to a specified value over a given time. - - \row - \o NumberAnimation - \o animate a numeric property from one value to another over a given time. - - \row - \o PauseAnimation - \o results in the task waiting for the specified duration, in milliseconds. - - \row - \o SequentialAnimation - \o allows us to list in order the animation events we want to occur, first A then B then C and so on. - - \row - \o ParallelAnimation - \o enables us to run different animations at the same time instead of sequentially. - -\endtable - - -\section1 Using States - -A state is a defined set of values in the configuration of an object and -often depends on the previous state. For example, a glass could be in a -state we call 'HalfFull' if it is being filled with a liquid and has -reached half of its total capacity. We could also have a state called -HalfEmpty which is the state that occurs when the amount of liquid drops to -half of the glass's capacity. Both states represent the same amount of -liquid, but we consider them different. Likewise, states in a program -represent not just values but may include how the current values were -reached. - -When a state changes a \e transition occurs. This is an opportunity to make -changes or take actions that depend on the movement to the new state. For -example, if we had a scene in the country where the state variable has two -states "daylight" and "night". Then when the state changes to "night" at -this transition the sky would be made dark, stars would be shown, the -countryside would be darkened. And when the state changes to "daylight" the -opposite changes would be made: the sky is now blue, the scenery is green, -there is a sun in the sky. - -Here is a simple QML program that shows the change of state in the above -example. We have two rectangles, the top one is the 'sky' and the bottom -one is the 'ground'. We will animate the change from daylight to night. -There will be two states, but we only need to define one since 'daylight' -will be the default state. We will just go to 'night' by clicking and -holding the left mouse button down, releasing the mouse button will reverse -the process - -\snippet doc/src/snippets/declarative/qml-intro/states1.qml document - -Several new things appear in this sample. Firstly, we use a \l MouseArea -element to detect mouse clicks in the \e mainRectangle. Secondly, we use -the list notation [ thing1 , thing2, ... ] to build a list of states and a -list of transitions. - -\l MouseArea defines a region that will respond to mouse clicks. In this case -we are only concerned with when the mouse is pressed or not pressed, not -the particular button or other details. The area of the MouseArea is the -entire main window, mainRectangle, so that clicking anywhere in this region -will start the animation. Since we are using the 'pressed' mouse state, -then the animation will move from 'daylight' to 'night' only while the mouse -button remains pressed. - -When the button is released the 'daylight' state is entered and the -transition from 'night' to 'daylight' is triggered causing the animation to -run. The transition specifies the duration in milliseconds of the -ColorAnimation, while the state specifies the color of the new state. - -The PropertyChanges command is the way that we nominate which properties -will change in a change of state, and what new value the property will -take. Since, for example, we want the 'sky' region to turn to dark blue and -the 'ground' region to turn to black for the 'night' state, then the -rectangles for those regions are the 'target' and the property in the target -is 'color'. - - -\section1 Signals - -Signals are simply events that can be hooked up to actions we want performed. -In QML they are usually preceded by the word 'on', for example in the animation -using a MouseArea the signal was \l {MouseArea::onPressed}{onPressed}. If -you look at the C++ documentation you will see a lot of talk about -\l {Signals & Slots}{Signals and Slots}. Signals are connected to Slots. The -signal represents an event and the Slot is the function that does something -based on that event. You can also have Signals connected to other Signals, so -that one Signal (event) triggers another Signal (event), and so forth. It is -nice to know this is what happens beneath the QML layer but not essential for -using QML. - -Most elements do not have Signals associated with them. However, a few like -the \l Audio element have many signals. Some of the \l Audio signals are -used to represent events such as when the audio is stopped, play is pressed, -paused, and reaching the end of the media. They allow the developer to connect, - for example, the press of a user interface button (perhaps a MouseArea) to - some QML that will handle this event. - - -\section1 Analyzing An Example: Dial Control - -In the Qt \e {examples/declarative/ui-components} folder you will find a folder -\e {dialcontrol} which contains the \e dialcontrol example. - -\image qml-dial.png "QML Dial example with Slider" - -In essence this small application has a sliding bar that you can slide using -a mouse, and a graphical dial that responds to the position of the slider. - -The code for the example is in two parts: Dial.qml and dialcontrol.qml. - -\e {Dial.qml} can be found in the \e content sub-directory. It defines a \c Dial -component similar to an odometer. Eventually, the example will hook up a slider -component so that moving the slider will change the position of a needle on the -dial. - -The code for the \c Dial, identified by the name of the file, contains four images -in overlapping order: the background (numbers and divisions), the shadow of the -needle, the needle itself, and finally the 'glass' overlay (containing -transparent layers). - -The \c needle_shadow.png image has a \l Rotation assigned to the \e transform -attribute of the \l Image. The rotation is set to match the angle of the needle -image angle value \e {needleRotation.angle}. Both the needle and the -needle_shadow have the same default \e x and \e y values but the rotation origin -for the needle is slightly different so that a shadow will be evident as the -needle moves. - -\snippet examples/declarative/ui-components/dialcontrol/content/Dial.qml needle_shadow - -And the needle - -\snippet examples/declarative/ui-components/dialcontrol/content/Dial.qml needle - -The final image is the overlay which simply has a position defined. - -\snippet examples/declarative/ui-components/dialcontrol/content/Dial.qml overlay - -\e {dialcontrol.qml} in the \e {examples/declarative/ui-components/dialcontrol} directory is the -main file of the example. It defines the visual environment that the Dial -will fit into. Because the \e Dial component and the images live in the \e -content sub-directory we will have to import this into \e dialcontrol.qml.

The new one does not work +and we need a solution quickly before this disaster brings down the company! I'm +putting you in charge of the whole project while I go on vacation -- see you in +2 weeks." + +\section1 Brainstorming Ideas - It is time to play! + +Never one to shy away from a challenge (especially when your job might be on the +line), you first set out try come up with an idea about what your options are. + +You ask around a bit and discover that the broken application was intended to +replace one that has been living on a dusty mainframe for the past 25 years. The +machine is nearing end of life and, rather than invest in replacement hardware +to run a legacy HelloWorld program, the board decided to invest in new software +that could be run on desktops, web, mobile devices and embedded into the +company's main product line -- a pocket size device with a small LCD screen, +which flashes the message "Hello World" every full moon. + +The vendor that was chosen to handle this task was a well known multinational +company that specialized in enterprise CRM/ERP systems. The project missed +several delivery deadlines over a 2 year period, and was 500% over budget. There +was not going to be much margin for error trying to fix the problem, and there +would likely be no budget either. + +You begin researching dozens of possible possible approaches to the problem. One +of the biggest challenges is that there are very few options that will allow you +to create native applications that use the same framework for targeting +\l{qt-creator-configure-target}{multiple platforms}. + +Some years ago you had coded a small desktop application using the Qt framework, +without realizing that it also can be used for targeting the web, mobile devices +and embedded devices. Since that time, Qt has added a new feature called \l{Qt +Quick}, which provides the ability to easily design applications with intuitive, +modern-looking, fluid user interfaces. + +\section1 Creating an Objective + +You quickly realize that you might need two, three, or more interfaces for your +application -- one for each of the target platforms you are aiming for. +Thankfully Qt has options well suited for each of them. + +For your mobile application the choice seems obvious enough. The new Qt Quick +technology looks very promising, but you do not know QML; the declarative +language that helps define the interface in a Qt Quick program. You still want +to give it a try, but worry that you might not have something complete before +your boss returns from vacation in two weeks. You also wonder if Qt Quick is +applicable to desktop and embedded targets -- and then of course there is the +need for something targeting the web. You decide to give Qt Quick a try first +and \l{QML Examples and Demos}{see where it takes you}. + +\section1 Developing Plans + +One thing you realize after reading up on \l{Qt Quick} is that things are very +different from the desktop when designing an interface. Qt Quick doesn't contain +ready made UI 'chrome'; the widgets and other design elements that define the +application interface. A new technology, called Qt Quick Components, looks like +a promising solution, but the components will only be available at a later date. +For now you'll have to come up with something on your own -- but you are keen to +give your design skills a work out, and learning to use Qt Quick seems to be a +great way to do it. + +Not knowing a better place to start, you begin by taking a cue from web design +and plan a wireframe, which helps +\l{http://doc.qt.nokia.com/qtcreator-snapshot/creator-visual-editor.html}{define the application layout}, +content and user interaction. You decide on breaking the field of the screen +space into three roughly equal size parts. There will be one section across the +top, which will span the width of the screen, and two sections in the lower +have, which will be approximately as tall as the top section is wide (when in +portrait mode). + +The top section will be a simple text representation of the phrase "Hello World" +in English. In the lower left you would like to place some kind of audio +playback feature that repeats back the phrase in the top section of the screen. +Finally, in the lower right hand side of the screen will be four links to +similar views for additional languages -- Mandarin Chinese, Brazilian +Portuguese, Arabic, and Russian. When the user clicks one of the links the text +at the top is then translated, and the playback corresponds to the appropriate +language. + +While the wireframe is effective in dealing with one part of the design +challenge, it does not cover visual aspects other than layout and content. This +means that you still need to define colours, white space, and typography (among +other things). This is where a style guide would come in handy, if your company +already had one that is. In the absence of one you decide to again get some +inspiration from the web, and you mimic some of the company's website design +into your application -- a sans-serif font for white text on a blue field across +the top, black text on white for the bottom two sections, and a small company +logo to the left of the "Hello World" message. + + +\section1 Execution: The Coding Begins! + +At long last you sit down to \l{qt-technologies}{implement} your plans and +designs. The first few steps go according to plan, and creating the basic layout +and text goes fairly smoothly -- but you run into a few challenges quite +quickly: + +Devising a user friendly interface to audio playback is not as intuitive as you +first thought. Since there exist a ready made component for +\l{http://doc.qt.nokia.com/qtmobility-1.1.0/qml-multimedia.html}{multimedia}, +you remove the bottom left field and now have the screen split in two. You add +textual links for each of the five target languages, and when the user clicks +one of them the message text changes and the appropriate audio plays back. It is +a small sacrifice to make for now, and you are sure there is a solution to be +found once you have become more proficient with QML. + +The next challenge you run into is that \l{qt-deployment}{deploying} the +application to a Symbian phone is not as clearly understood as you expected. +Again you are sure there is something you are missing, but for the time being +you manually copy the .sis file to the "Installs" directory on the phone +(connected to the development machine by USB) and then install it through the +Application Manager. + +When you finally manage to install the application on the device you notice +something that looks rather peculiar, and something you had not thought of.

In particular, it can cope with different screen + sizes, DPI, and aspect ratios. You need to consider scalability + when: + + \list + \o your application will be deployed to more than one device + handset, or more than one device form factor. + \o your application will be deployed for a long period of time, + so that new device handsets might appear on the market after + your initial deployment. + \endlist + + This document discusses how scalable applications can be created. + + \section1 Developing Scalable UIs + + This section shows the basics of how we advice scalable + applications to be implemented using QML. We recommend that you + follow these techniques: + + \list + \o Create separate top-level layout + definitions for each form factor. + \o Keep the layouts small and let components + scale relative to their immediate parent. + \o Define device independent measurements, such as dp + (device independent pixels), and use + these to scale components and for layout measurement. + \o Define layouts in a + proportional way using the built-in layout features of QML. + \endlist + + Using small top-level layouts makes your codebase smaller and + easier to maintain. Also, components that scales relative to their + parent are more reusable. The layouts should be children of the + application's root item. You can change between them by, for + instance, using the opacity property of Item; that is, if your + application has more tham one top-level layout. Such a top-level + layout is also often referred to as a page, i.e., a layout that + uses the entire screen. For instance, an organizer application + will typically have separate pages for showing the calender and + editing todo items. + + You should define the measurements separate from the UI, for + instance by using a JavaScript object that you fill in with a + script on application start up. + + QML provides several ways of laying out components, e.g, using + anchor based layout, the more classic Grid; Column; and Row + elements, and by setting the dimensions of Items directly. When + laying out components in scalable applications, you should + generally prefer using anchors and set width and height based on + parent size where possible. Layouts are not only relevant to + top-level layouts; components often contain child Items. + + The following sections describe in more detail the different + aspects of scalability that should be considered in order to + achieve the desired level of flexibility within your application. + + \section1 Implementing the Top-Level Layouts + + As mentioned, each application should use separate top-level + layout QML definitions to support separate layout configurations / + form factors. + + Consider an application that has to be deployed to at least two + devices, which both have very different screen sizes and DPI + values. The two form factors of the application will share many + common components and attributes, and will most likely connect to + the same data model. + + Therefore, the top-level definitions should be quite + straightforward and short, with the majority of the functionality + refactored into contained Components. It is important to try to + avoid unnecessary duplication between these top-level definitions, + in order to improve maintainability. + + There are some patterns that you might consider when designing + your top level layouts: + + \list + \o In some cases, the contents of an entire page in a smaller + handset could form a component element of a layout in a + larger device. Therefore, consider making that a separate + component (i.e. defined in a separate QML file), and in the + smaller handset, the Page will simply contain an instance of + that component. On the larger device, there may be enough + space to show two separate items. For example, in an email + viewer, if the screen is large enough, it may be possible to + show the email list view, and the email reader view side by + side. + \o In some cases, the contents of a view might be quite similar + on all screen sizes, but with an expanded content area. In + this case, it may be possible to re-use the same layout + definition, if defined appropriately using anchors. + \endlist + + The \l{Loader} component can be used to load separate QML files + based on some criteria, such as Device Profile (configuration of + screen pixel resolution and DPI density). In the case of form + factor, this information will not change during the application's + lifetime, therefore there is no issue with memory usage or + performance. + + \section1 Defining Measurements + + When you are defining the measurements within an application or + component layout, there are a number aspects to consider: + + \list + \o The layout structure, the high-level relationship between + items. Which item is the parent? How are the items arranged + relatively on the screen? Are they in a grid or column? + \o The layout measurements. How big is an item, or a margin + inside the edge of an item, or an anchor between items? + \o The implicit size of contained items. Some child items will + require a certain amount of space, such as a button + containing a text. That may also depend on the current + platform and style. How do you ensure that you leave enough + space, and what happens if your children change size? + \endlist + + These aspects combine together to resolve the final layout for a + given Device Profile. However, although there are dependencies + between them, it is important to manage and control the different + aspects separately. + + It is strongly recommended that Layout measurements should be + stored in a separate place from the component layout structure + definition files. The reason for this is that layout structure, + for a given form factor, can be re-used for different Device + Profiles. However, measurements will almost always vary between + Device Profiles or Device Categories. + + If the opposite approach (complete duplication of entire QML + files) was taken, then all of the layout states and structure + definitions would be duplicated between the copied QML files, and + only the measurement values would change. + + The main benefit of using separate measurement definition files + are: + + \list + \o To reduce the amount of duplication, and hence increase + maintainability. + \o It becomes much easier to change the layout structure, + perhaps due to subsequent specification changes. In that + case, the layout structure can be modified once, and many or + all of the layout measurements would remain unchanged. + \o It becomes much easier to add support for additional Device + Profiles, simply by adding another measurement definition + file. + \endlist + + \section1 Using QML's Layout Features + + For a given form factor, top-level Layouts structure definitions, + or component layout structure definitions, should in general be + defined in a proportional way using a combination of + + \list + \o \l{Item::anchors.top}{anchors} within an Item + \o \l{Row} / \l{Column} / \l{Grid} + \o simple javascript expressions such as width: Math.round(parent.width / 3.0). + \endlist + + These basic building blocks, along with the powerful evaluation + capabilities of javascript expressions within every QML binding, + are designed to allow the majority of the layout structure + definition to be defined in a Device Profile independent way. + + There are some limitations of the basic grid type layouts. They + are designed to accommodate a number of Items, but use the current + sizes of those items. There is a similar issue with the basic + anchor type layout. In particular, it can be difficult to spread a + number of child items proportionately across an area of their + container. + + By combining the features of the layout managers with simple + javascript expressions, a richer variety of designs can be + expressed, without having to resort to additional layout + measurement parameters or measurement values. + + Here are some things not to do with layouts: + + \list + \o Don't define complex javascript functions that are regularly + evaluated. This will cause poor performance, particularly + during animated transitions. + \o Don't define all of your layouts using x, y, width and + height. Reserve this for items that cannot easily be defined + using anchors (anchors are evaluated in a more efficient + way). + \o Don't make assumptions about the container size, or about + the size of child items. Try to make flexible layout + definitions that can absorb changes in the available space. + \endlist + + \section1 Orientation Switches + + Application top-level page definitions, and reusable component + definitions, should use one QML layout definition for the layout + structure. This single definition should include the layout design + for separate Device Orientations and Aspect Ratios. The reason for + this is that performance during an orientation switch is critical, + and it is therefore a good idea to ensure that all of the + components needed by both orientations are loaded when the + orientation changes. + + On the contrary, you should perform thorough tests if you choose + to use a \l{Loader} to load additional QML that is needed in separate + orientations, as this will affect the performance of the + orientation change. + + In order to enable layout animations between the orientations, the + anchor definitions must reside within the same containing + component. Therefore the structure of a page or a component + should consist of a common set of child components, a common set + of anchor definitions, and a collection of states (defined in a + StateGroup) representing the different aspect ratios supported by + the component. (However note that orientation change animations + are not possible on Symbian due to compatibility support for S60 + applications). + + If a component contained within a page needs to be + hosted in numerous different form factor definitions, then the + layout states of the view should depend on the aspect ratio of the + page (its immediate container). Similarly, different instances of + a component might be situated within numerous different containers + in a UI, and so its layout states should be determined by the + aspect ratio of its parent. The conclusion is that layout states + should always follow the aspect ratio of the direct container (not + the "orientation" of the current device screen). + + Within each layout \l{State}, you should define the relationships + between items using native QML layout definitions. See below for + more information. During transitions between the states (triggered + by the top level orientation change), in the case of anchor + layouts, AnchorAnimation elements can be used to control the + transitions. In some cases, you can also use a NumberAnimation on + e.g. the width of an item. Remember to avoid complex javascript + calculations during each frame of animation. Using simple anchor + definitions and anchor animations can help with this in the + majority of cases. + + There are a few additional cases to consider: + + \list + \o What if you have a single page that looks completely + different between landscape and portrait, i.e. all of the + child items are different? For each page, have two child + components, with separate layout definitions, and make one + or other of the items have zero opacity in each state. You + can use a cross-fade animation by simply applying a + NumberAnimation transition to the opacity. + \o What if you have a single page that shares 30% or more of + the same layout contents between portrait and landscape? In + that case, consider having one component with landscape and + portrait states, and a collection of separate child items + whose opacity (or position) depends on the orientation + state. This will enable you to use layout animations for the + items that are shared between the orientations, whilst the + other items are either faded in/out, or animated on/off + screen. + \o What if you have two pages on a handheld device that need to + be on screen at the same time, for example on a larger form + factor device? In this case, notice that your view component + will no longer be occupying the full screen. Therefore it's + important to remember in all components (in particular, list + delegate items) should depend on the size of the containing + component width, not on the screen width. It may be + necessary to set the width in a Component.onCompleted() + handler in this case, to ensure that the list item delegate + has been constructed before the value is set. + \o What if the two orientations take up too much memory to have + them both in memory at once? Use a \l{Loader} if necessary, if + you cannot keep both versions of the view in memory at once, + but beware performance on the cross-fade animation during + layout switch. One solution could be to have two "splash + screen" items that are children of the Page, then you cross + fade between those during rotation. Then you can use a + \l{Loader} to load another child component that loads the actual + model data to another child Item, and cross-fade to that + when the \l{Loader} has completed. + \endlist + */ + diff --git a/doc/src/howtos/unix-signal-handlers.qdoc b/doc/src/howtos/unix-signal-handlers.qdoc index 2fa558e..20beb38 100644 --- a/doc/src/howtos/unix-signal-handlers.qdoc +++ b/doc/src/howtos/unix-signal-handlers.qdoc @@ -59,7 +59,7 @@ sigaction(2) man pages before plowing through the following code snippets. - \snippet doc/src/snippets/code/doc_src_unix-signal-handlers.qdoc 0 + \snippet doc/src/snippets/code/doc_src_unix-signal-handlers.cpp 0 In the MyDaemon constructor, use the socketpair(2) function to initialize each file descriptor pair, and then create the @@ -68,24 +68,24 @@ appropriate slot function, which effectively converts the Unix signal to the QSocketNotifier::activated() signal. - \snippet doc/src/snippets/code/doc_src_unix-signal-handlers.qdoc 1 + \snippet doc/src/snippets/code/doc_src_unix-signal-handlers.cpp 1 Somewhere else in your startup code, you install your Unix signal handlers with sigaction(2). - \snippet doc/src/snippets/code/doc_src_unix-signal-handlers.qdoc 2 + \snippet doc/src/snippets/code/doc_src_unix-signal-handlers.cpp 2 In your Unix signal handlers, you write a byte to the \e write end of a socket pair and return.

So how do + threads differ from processes? While you are making calculations on a + spreadsheet, there may also be a media player running on the same desktop + playing your favorite song. Here is an example of two processes working in + parallel: one running the spreadsheet program; one running a media player. + Multitasking is a well known term for this. A closer look at the media + player reveals that there are again things going on in parallel within one + single process. While the media player is sending music to the audio driver, + the user interface with all its bells and whistles is being constantly + updated. This is what threads are for \mdash concurrency within one single + process. + + So how is concurrency implemented? Parallel work on single core CPUs is an + illusion which is somewhat similar to the illusion of moving images in + cinema. + For processes, the illusion is produced by interrupting the processor's + work on one process after a very short time. Then the processor moves on to + the next process. In order to switch between processes, the current program + counter is saved and the next processor's program counter is loaded. This + is not sufficient because the same needs to be done with registers and + certain architecture and OS specific data. + + Just as one CPU can power two or more processes, it is also possible to let + the CPU run on two different code segments of one single process. When a + process starts, it always executes one code segment and therefore the + process is said to have one thread. However, the program may decide to + start a second thread. Then, two different code sequences are processed + simultaneously inside one process. Concurrency is achieved on single core + CPUs by repeatedly saving program counters and registers then loading the + next thread's program counters and registers. No cooperation from the + program is required to cycle between the active threads. A thread may be in + any state when the switch to the next thread occurs. + + The current trend in CPU design is to have several cores. A typical + single-threaded application can make use of only one core. However, a + program with multiple threads can be assigned to multiple cores, making + things happen in a truly concurrent way. As a result, distributing work + to more than one thread can make a program run much faster on multicore + CPUs because additional cores can be used. + + \section2 GUI Thread and Worker Thread + + As mentioned, each program has one thread when it is started. This thread + is called the "main thread" (also known as the "GUI thread" in Qt + applications). The Qt GUI must run in this thread. All widgets and several + related classes, for example QPixmap, don't work in secondary threads. + A secondary thread is commonly referred to as a "worker thread" because it + is used to offload processing work from the main thread. + + \section2 Simultaneous Access to Data + + Each thread has its own stack, which means each thread has its own call + history and local variables. Unlike processes, threads share the same + address space. The following diagram shows how the building blocks of + threads are located in memory. Program counter and registers of inactive + threads are typically kept in kernel space. There is a shared copy of the + code and a separate stack for each thread. + + \image threadvisual-example.png "Thread visualization" + + If two threads have a pointer to the same object, it is possible that both + threads will access that object at the same time and this can potentially + destroy the object's integrity. It's easy to imagine the many things that + can go wrong when two methods of the same object are executed + simultaneously. + + Sometimes it is necessary to access one object from different threads; + for example, when objects living in different threads need to communicate. + Since threads use the same address space, it is easier and faster for + threads to exchange data than it is for processes. Data does not have to be + serialized and copied. Passing pointers is possible, but there must be a + strict coordination of what thread touches which object. Simultaneous + execution of operations on one object must be prevented. There are several + ways of achieving this and some of them are described below. + + So what can be done safely? All objects created in a thread can be used + safely within that thread provided that other threads don't have references + to them and objects don't have implicit coupling with other threads. Such + implicit coupling may happen when data is shared between instances as with + static members, singletons or global data. Familiarize yourself with the + concept of \l{Reentrancy and Thread-Safety}{thread safe and reentrant} + classes and functions. + + \section1 Using Threads + + There are basically two use cases for threads: + + \list + \o Make processing faster by making use of multicore processors. + \o Keep the GUI thread or other time critical threads responsive by + offloading long lasting processing or blocking calls to other threads. + \endlist + + \section2 When to Use Alternatives to Threads + + Developers need to be very careful with threads. It is easy to start other + threads, but very hard to ensure that all shared data remains consistent. + Problems are often hard to find because they may only show up once in a + while or only on specific hardware configurations. Before creating threads + to solve certain problems, possible alternatives should be considered. + + \table + \header + \o Alternative + \o Comment + \row + \o QEventLoop::processEvents() + \o Calling QEventLoop::processEvents() repeatedly during a + time-consuming calculation prevents GUI blocking. However, this + solution doesn't scale well because the call to processEvents() may + occur too often, or not often enough, depending on hardware. + \row + \o QTimer + \o Background processing can sometimes be done conveniently using a + timer to schedule execution of a slot at some point in the future. + A timer with an interval of 0 will time out as soon as there are no + more events to process. + \row + \o QSocketNotifier QNetworkAccessManager QIODevice::readyRead() + \o This is an alternative to having one or multiple threads, each with + a blocking read on a slow network connection. As long as the + calculation in response to a chunk of network data can be executed + quickly, this reactive design is better than synchronous waiting in + threads. Reactive design is less error prone and energy efficient + than threading. In many cases there are also performance benefits. + \endtable + + In general, it is recommended to only use safe and tested paths and to + avoid introducing ad-hoc threading concepts. QtConcurrent provides an easy + interface for distributing work to all of the processor's cores. The + threading code is completely hidden in the QtConcurrent framework, so you + don't have to take care of the details. However, QtConcurrent can't be used + when communication with the running thread is needed, and it shouldn't be + used to handle blocking operations. + + \section2 Which Qt Thread Technology Should You Use? + + Sometimes you want to do more than just running a method in the context of + another thread. You may want to have an object which lives in another + thread that provides a service to the GUI thread. Maybe you want another + thread to stay alive forever to poll hardware ports and send a signal to + the GUI thread when something noteworthy has happened. Qt provides + different solutions for developing threaded applications. The right + solution depends on the purpose of the new thread as well as on the + thread's lifetime. + + \table + \header + \o Lifetime of thread + \o Development task + \o Solution + \row + \o One call + \o Run one method within another thread and quit the thread when the + method is finished. + \o Qt provides different solutions: + \list + \o Write a function and run it with QtConcurrent::run() + \o Derive a class from QRunnable and run it in the global thread + pool with QThreadPool::globalInstance()->start() + \o Derive a class from QThread, reimplement the QThread::run() + method and use QThread::start() to run it. + \endlist + + \row + \o One call + \o Operations are to be performed on all items of a container. + Processing should be performed using all available cores. A common + example is to produce thumbnails from a list of images. + \o QtConcurrent provides the \l{QtConcurrent::}{map()} function for + applying operations on every container element, + \l{QtConcurrent::}{filter()} for selecting container elements, and + the option of specifying a reduce function for combining the + remaining elements. + \row + \o One call + \o A long running operation has to be put in another thread. During the + course of processing, status information should be sent to the GUI + thread. + \o Use QThread, reimplement run and emit signals as needed. Connect the + signals to the GUI thread's slots using queued signal/slot + connections. + + \row + \o Permanent + \o Have an object living in another thread and let it perform different + tasks upon request. + This means communication to and from the worker thread is required. + \o Derive a class from QObject and implement the necessary slots and + signals, move the object to a thread with a running event loop and + communicate with the object over queued signal/slot connections. + \row + \o Permanent + \o Have an object living in another thread, let the object perform + repeated tasks such as polling a port and enable communication with + the GUI thread. + \o Same as above but also use a timer in the worker thread to implement + polling. However, the best solution for polling is to avoid it + completely. Sometimes using QSocketNotifier is an alternative. + \endtable + + + \section1 Qt Thread Basics + + QThread is a very convenient cross platform abstraction of native platform + threads. Starting a thread is very simple. Let us look at a short piece of + code that generates another thread which says hello in that thread and then + exits. + + \snippet examples/tutorials/threads/hellothread/hellothread.h 1 + + We derive a class from QThread and reimplement the \l{QThread::}{run()} + method. + + \snippet examples/tutorials/threads/hellothread/hellothread.cpp 1 + + The run method contains the code that will be run in a separate thread. In + this example, a message containing the thread ID will be printed. + QThread::start() will call the method in another thread. + + \snippet examples/tutorials/threads/hellothread/main.cpp 1 + + To start the thread, our thread object needs to be instantiated. The + \l{QThread::}{start()} method creates a new thread and calls the + reimplemented \l{QThread::}{run()} method in this new thread. Right after + \l{QThread::}{start()} is called, two program counters walk through the + program code. The main function starts with only the GUI thread running and + it should terminate with only the GUI thread running. Exiting the program + when another thread is still busy is a programming error, and therefore, + wait is called which blocks the calling thread until the + \l{QThread::}{run()} method has completed. + + This is the result of running the code: + + \badcode + hello from GUI thread 3079423696 + hello from worker thread 3076111216 + \endcode + + + \section2 QObject and Threads + + A QObject is said to have a \e{thread affinity} or, in other words, that it + lives in a certain thread. This means that, at creation time, QObject saves + a pointer to the current thread. This information becomes relevant when an + event is posted with \l{QCoreApplication::}{postEvent()}. The event will be + put in the corresponding thread's event loop. If the thread where the + QObject lives doesn't have an event loop, the event will never be delivered. + + To start an event loop, \l{QThread::}{exec()} must be called inside + \l{QThread::}{run()}. Thread affinity can be changed using + \l{QObject::}{moveToThread()}. + + As mentioned above, developers must always be careful when calling objects' + methods from other threads. Thread affinity does not change this situation. + Qt documentation marks several methods as thread-safe. + \l{QCoreApplication::}{postEvent()} is a noteworthy example. A thread-safe + method may be called from different threads simultaneously. + + In cases where there is usually no concurrent access to methods, calling + non-thread-safe methods of objects in other threads may work thousands + of times before a concurrent access occurs, causing unexpected behavior. + Writing test code does not entirely ensure thread correctness, but it is + still important. + On Linux, Valgrind and Helgrind can help detect threading errors. + + The anatomy of QThread is quite interesting: + + \list + \o QThread does not live in the new thread where \l{QThread::}{run()} is + executed. It lives in the old thread. + \o Most QThread methods are the thread's control interface and are meant to + be called from the old thread. Do not move this interface to the newly + created thread using \l{QObject::}{moveToThread()}; i.e., calling + \l{QObject::moveToThread()}{moveToThread(this)} is regarded as bad + practice. + \o \l{QThread::}{exec()} and the static methods + \l{QThread::}{usleep()}, \l{QThread::}{msleep()}, + \l{QThread::}{sleep()} are meant to be called from the newly created + thread. + \o Additional members defined in the QThread subclass are + accessible by both threads. The developer is responsible for + coordinating access. A typical strategy is to set the members before + \l{QThread::}{start()} is called. Once the worker thread is running, + the main thread should not touch the additional members anymore. After + the worker has terminated, the main thread can access the additional + members again. This is a convenient strategy for passing parameters to a + thread before it is started as well as for collecting the result once it + has terminated. + \endlist + + A QObject's parent must always be in the same thread. This has a surprising + consequence for objects generated within the \l{QThread::}{run()} method: + + \code + void HelloThread::run() + { + QObject *object1 = new QObject(this); //error, parent must be in the same thread + QObject object2; // OK + QSharedPointer <QObject> object3(new QObject); // OK + } + \endcode + + \section2 Using a Mutex to Protect the Integrity of Data + + A mutex is an object that has \l{QMutex::}{lock()} and \l{QMutex::}{unlock()} + methods and remembers if it is already locked. A mutex is designed to be + called from multiple threads. \l{QMutex::}{lock()} returns immediately if + the mutex is not locked. The next call from another thread will find the + mutex in a locked state and then \l{QMutex::}{lock()} will block the thread + until the other thread calls \l{QMutex::}{unlock()}. This functionality can + make sure that a code section will be executed by only one thread at a time. + + The following line sketches how a mutex can be used to make a method + thread-safe: + + \code + void Worker::work() + { + this->mutex.lock(); // first thread can pass, other threads will be blocked here + doWork(); + this->mutex.unlock(); + } + \endcode + + What happens if one thread does not unlock a mutex? The result can be a + frozen application. In the example above, an exception might be thrown and + \c{mutex.unlock()} will never be reached. To prevent problems like this, + QMutexLocker should be used. + + \code + void Worker::work() + { + QMutexLocker locker(&mutex); // Locks the mutex and unlocks when locker exits the scope + doWork(); + } + \endcode + + This looks easy, but mutexes introduce a new class of problems: deadlocks. + A deadlock happens when a thread waits for a mutex to become unlocked, but + the mutex remains locked because the owning thread is waiting for the first + thread to unlock it. The result is a frozen application. Mutexes can be + used to make a method thread safe. Most Qt methods aren't thread safe + because there is always a performance penalty when using mutexes. + + It isn't always possible to lock and unlock a mutex in a method. Sometimes + the need to lock spans several calls. For example, modifying a container + with an iterator requires a sequence of several calls which should not be + interrupted by other threads. In such a scenario, locking can be achieved + with a mutex that is kept outside of the object to be manipulated. With an + external mutex, the duration of locking can be adjusted to the needs of the + operation. One disadvantage is that external mutexes aid locking, but do + not enforce it because users of the object may forget to use it. + + \section2 Using the Event Loop to Prevent Data Corruption + + The event loops of Qt are a very valuable tool for inter-thread + communication. Every thread may have its own event loop. A safe way of + calling a slot in another thread is by placing that call in another + thread's event loop. This ensures that the target object finishes the + method that is currently running before another method is started. + + So how is it possible to put a method invocation in an event loop? Qt has + two ways of doing this. One way is via queued signal-slot connections; the + other way is to post an event with QCoreApplication::postEvent(). A queued + signal-slot connection is a signal slot connection that is executed + asynchronously. The internal implementation is based on posted events. The + arguments of the signal are put into the event loop and the signal method + returns immediately. + + The connected slot will be executed at a time which depends on what else is + in the event loop. + + Communication via the event loop eliminates the deadlock problem we face + when using mutexes. This is why we recommend using the event loop rather + than locking an object using a mutex. + + \section2 Dealing with Asynchronous Execution + + One way to obtain a worker thread's result is by waiting for the thread + to terminate. In many cases, however, a blocking wait isn't acceptable. The + alternative to a blocking wait are asynchronous result deliveries with + either posted events or queued signals and slots. This generates a certain + overhead because an operation's result does not appear on the next source + line, but in a slot located somewhere else in the source file. Qt + developers are used to working with this kind of asynchronous behavior + because it is much similar to the kind of event-driven programming used in + GUI applications. + + \section1 Examples + + This tutorial comes with examples for Qt's three basic ways of working with + threads. Two more examples show how to communicate with a running thread + and how a QObject can be placed in another thread, providing service to the + main thread. + + \list + \o Using QThread as shown \l{Qt thread basics}{above} + \o \l{Example 1: Using the Thread Pool}{Using the global QThreadPool} + \o \l{Example 2: Using QtConcurrent}{Using QtConcurrent} + \o \l{Example 3: Clock}{Communication with the GUI thread} + \o \l{Example 4: A Permanent Thread}{A permanent QObject in another thread + provides service to the main thread} + \endlist + + The following examples can all be compiled and run independently. The source can + be found in the examples directory: examples/tutorials/threads/ + + \section2 Example 1: Using the Thread Pool + + Creating and destroying threads frequently can be expensive. To avoid the + cost of thread creation, a thread pool can be used. A thread pool is a + place where threads can be parked and fetched. We can write the same + "hello thread" program as \l{Qt Thread Basics}{above} using the global + thread pool. We derive a class from QRunnable. The code we want to run in + another thread needs to be placed in the reimplemented QRunnable::run() + method. + + \snippet examples/tutorials/threads/hellothreadpool/hellothreadpool.cpp 1 + + We instantiate Work in main(), locate the global thread pool and use the + QThreadPool::start() method. Now the thread pool runs our worker in another + thread. Using the thread pool has a performance advantage because threads + are not destroyed after they have finished running. They are kept in a pool + and wait to be used again later. + + \section2 Example 2: Using QtConcurrent + + \snippet examples/tutorials/threads/helloconcurrent/helloconcurrent.cpp 1 + + We write a global function hello() to implement the work. QtConcurrent::run() + is used to run the function in another thread. The result is a QFuture. + QFuture provides a method called \l{QFuture::}{waitForFinished()}, which + blocks until the calculation is completed. The real power of QtConcurrent + becomes visible when data can be made available in a container. QtConcurrent + provides several functions that are able to process itemized data on all + available cores simultaneously. The use of QtConcurrent is very similar to + applying an STL algorithm to an STL container. + \l{examples-threadandconcurrent.html}{QtConcurrent Map} is a very short and + clear example about how a container of images can be scaled on all available + cores. The image scaling example uses the blocking variants of the functions + used. For every blocking function there is also a non-blocking, asynchronous + counterpart. Getting results asynchronously is implemented with QFuture and + QFutureWatcher. + + \section2 Example 3: Clock + + \image thread_clock.png "clock" + + We want to produce a clock application. The application has a GUI and a + worker thread. The worker thread checks every 10 milliseconds what time it + is. If the formatted time has changed, the result will be sent to the GUI + thread where it is displayed. + + Of course, this is an overly complicated way of designing a clock and, + actually, a separate thread is unnecessary. We would be better off placing + the timer in the main thread because the calculation made in the timer slot + is very short-lived. This example is purely for instructional use and shows + how to communicate from a worker thread to a GUI thread. Note that + communication in this direction is easy. We only need to add a signal + to QThread and make a queued signal/slot connection to the main thread. + Communication from the GUI to the worker thread is shown in the next + example. + + \snippet examples/tutorials/threads/clock/main.cpp 1 + + We've connected the \c clockThread with the label. The connection must be a + queued signal-slot connection because we want to put the call in the event + loop. + + \snippet examples/tutorials/threads/clock/clockthread.h 1 + + We have derived a class from QThread and declared the \c sendTime() signal. + + \snippet examples/tutorials/threads/clock/clockthread.cpp 1 + + The trickiest part of this example is that the timer is connected to its + slot via a direct connection. A default connection would produce a queued + signal-slot connection because the connected objects live in different + threads; remember that QThread does not live in the thread it creates. + + Still it is safe to access ClockThread::timerHit() from the worker thread + because ClockThread::timerHit() is private and only touches local variables + and a private member that isn't touched by public methods. + QDateTime::currentDateTime() isn't marked as thread-safe in Qt + documentation, however we can get away with using it in this small + example because we know that the QDateTime::currentDateTime() static + method isn't used in any other threads. + + \section2 Example 4: A Permanent Thread + + This example shows how it is possible to have a QObject in a worker thread + that accepts requests from the GUI thread, does polling using a timer and + continuously reports results back to the GUI thread. The actual work + including the polling must be implemented in a class derived from QObject. + We have called this class \c WorkerObject in the code shown below. The + thread-specific code is hidden in a class called \c Thread, derived from + QThread. + \c Thread has two additional public members. The \c launchWorker() member + takes the worker object and moves it to another thread with a started event + loop. + The call blocks for a very short moment until the thread creation operation + is completed, allowing the worker object to be used again on the next line. + The \c Thread class's code is short but somewhat involved, so we only show + how to use the class. + + \snippet examples/tutorials/threads/movedobject/main.cpp 1 + + QMetaObject::invokeMethod() calls a slot via the event loop. The worker + object's methods should not be called directly after the object has been + moved to another thread. We let the worker thread do some work and polling, + and use a timer to shut the application down after 3 seconds. Shutting the + worker down needs some care. We call \c{Thread::stop()} to exit the event + loop. We wait for the thread to terminate and, after this has occurred, we + delete the worker. + + \section1 Digging Deeper + + Threading is a very complicated subject. Qt offers more classes for + threading than we have presented in this tutorial.
