-\title Extending Types from QML
+\title Writing QML Components: Properties, Methods and Signals
 
-Many of the elements available for use in QML are implemented in
-\l {Extending QML in C++}{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.
+One of the key concepts in QML is the ability to define your own QML components that suit
+the purposes of your application. The standard \l {QML Elements} provide the essential components
+for creating a QML application; beyond these, you can write your own custom components that can
+be created and reused, without the use of C++.
 
-\tableofcontents
+Components are the building blocks of a QML project. When writing a QML application, whether
+large or small, it is best to separate QML code into smaller components that perform specific
+sets of operations, instead of creating mammoth QML files with large, combined functionality
+that is more difficult to manage and may contain duplicated code.
+
+
+\section1 Defining New Components
+
+A component is a reusable type with a well-defined interface, built entirely in QML.
+Any snippet of QML code can become a component, by placing the code in a file "<Name>.qml" where
+<Name> is the new component name, beginning 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.
 
-\section1 Adding new properties
+For example, one of the simplest and most common components you can build in QML is a
+button-type component. Below, we implement this component as a \l Rectangle with a clickable
+\l MouseArea, in a file named \c Button.qml:
 
-New properties can be added to an existing type using the \c property keyword.
-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.
+\snippet doc/src/snippets/declarative/qml-extending-types/components/Button.qml 0
 
-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.
+Now this component can be reused by another file within the same directory. Since the file is
+named \c Button.qml, the component is referred to as \c Button:
 
 \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 QDateTime
-\row \o variant \o QVariant
+\row
+\o \snippet doc/src/snippets/declarative/qml-extending-types/components/application.qml 0
+\o \image qml-extending-types.png
 \endtable
 
-From QML you can also declare object and list properties using any element name
-like this:
+The root object in \c Button.qml defines the attributes that are available to users of the
+\c Button component. In this case, the root object is a \l Rectangle, so any properties, methods
+and signals of \l Rectangle are made available, allowing \c application.qml to
+customize the \c width, \c height, \c radius and \c color properties of \c Button objects.
 
-\code
-    property QtObject objectProperty
-    property Item itemProperty
-    property MyCustomType customProperty
-    property list<Item> listOfItemsProperty
-\endcode
 
-Custom types must be registered with qmlRegisterType() to be usable as a property
-type. Also note that list properties cannot be modified like ordinary JavaScript
-arrays; see the \l {list}{list type documentation} for details.
+If \c Button.qml was not in the same directory, \c application.qml would need to load it as a
+\l {Modules}{module} from a specific filesystem path or \l{QDeclarativeExtensionPlugin}{plugin}.
+Also, note the letter case of the component file name is significant on some (notably UNIX)
+filesystems. It is recommended the file name case matches the case of the QML component name
+exactly - for example, \c Box.qml and not \c BoX.qml - regardless of the platform to which the
+QML component will be deployed.
+
+To write a useful component, it is generally necessary to provide it with custom attributes that store and
+communicate specific data. This is achieved by adding the following attributes to your components:
 
-QML supports two methods for adding a new property to a type: a new property
-definition, and a property alias. These are shown below.
+\list
+\o \bold Properties that can be accessed externally to modify an object (for example, \l Item has
+   \l {Item::}{width} and \l {Item::}{height} properties) and used in \l {Property Binding}
+\o \bold Methods of JavaScript code can be invoked internally or externally (for example,
+   \l Animation has a \l {Animation::}{start()} method)
+\o \bold Signals to notify other objects when an event has occurred (for example, MouseArea has a
+   \c clicked signal)
+\endlist
+
+The following sections show how these attributes can be added to QML components.
 
-\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.
+\section1 Adding Properties
+
+A property is a value of a QML component that can be read and modified by other objects. For
+example, a \l Rectangle component has \l {Item::}{width}, \l {Item::}{height} and \l
+{Rectangle::}{color} properties. Significantly, properties be used with \l {Property Binding}, where
+a property value is automatically updated using the value of another property.
 
 The syntax for defining a new property is:
+
 \code
-    [default] property <type> <name>[: defaultValue]
+[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.
+A \c property declaration can appear anywhere within a QML component definition, but it is customary
+to place it at the top. A component cannot declare more than one property with the same name. (It is
+possible to have a property name that is the same as an existing property in a type, but this is not
+recommended as the existing property becomes hidden and 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:
+Below is an example. The \c ImageViewer component has defined a \c string type property named
+\c currentImage, and its initial value is "default-image.png". This property is used to set the image
+displayed in the child \l Image object. Another file, \c application.qml, can create
+an \c ImageViewer object and read or modify the \c currentImage value:
 
-\code
-    // Use default value
-    property int myProperty: 10
+\table
+\row
+\o \snippet doc/src/snippets/declarative/qml-extending-types/properties/ImageViewer.qml 0
+\o \snippet doc/src/snippets/declarative/qml-extending-types/properties/application.qml 0
+\endtable
 
-    // Longer, but behaviorally identical
-    property int myProperty
-    myProperty: 10
-\endcode
+It is optional for a property to have a default value. The default value is a convenient shortcut, and is
+behaviorally identical to doing it in two steps, like this:
+
+\qml
+// Use default value
+property int myProperty: 10
+
+// Longer, but behaviorally identical
+property int myProperty
+myProperty: 10
+\endqml
+
+
+\section2 Supported property types
+
+All QML properties are typed. The examples above show properties with \c int and \c string types;
+notice that the type of the property must be declared. The type is used to determine the property
+behavior, and how the property is defined in C++.
 
-If a default value is not supplied or set later in the file, each type has a
-default value for when none is explicitly set. Below are the default values
-of some of the types. For the remaining types the default values are undefined.
+A number of property types are supported by default. These are listed in the table below,
+with their default values and the corresponding C++ type:
 
 \table
-\header \o QML Type \o Default Value
-\row \o bool \o false
-\row \o int \o 0
-\row \o double, real \o 0.0
-\row \o string, url \o "" (an empty string)
-\row \o color \o #000000 (black)
+\header \o QML Type Name \o Default value \o C++ Type Name
+\row \o int \o 0 \o int
+\row \o bool \o \c false \o bool
+\row \o double \o 0.0 \o double
+\row \o real \o 0.0 \o double
+\row \o string \o "" (empty string) \o QString
+\row \o url \o "" (empty url) \o QUrl
+\row \o color \o #000000 (black) \o QColor
+\row \o date \o \c undefined \o QDateTime
+\row \o variant \o \c undefined \o QVariant
 \endtable
 
-The following example shows how to declare a new "innerColor" property that
-controls the color of the inner rectangle.
+QML object types can also be used as property types. This includes
+\l {Defining new QML elements}{custom QML types} implemented in C++. Such properties are
+defined like this:
 
-\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
+\qml
+property Item itemProperty
+property QtObject objectProperty
+property MyCustomType customProperty
+\endqml
 
+Such object-type properties default to an \c undefined value.
 
-\section3 Property signal handlers
+\l{list}{List properties} are created with the \c list<Type> syntax, and default to an empty
+list:
 
-Adding a property to an item automatically adds a \e{value-changed}
-signal handler to the item. The signal hander is named
-\c{on<Property_name>Changed}, with the first letter of the property
-name being upper case.
+\qml
+property list<Item> listOfItems
+\endqml
 
-Signal handlers can have arbitrary JavaScript code assigned. The following 
-example shows how to output to a text console a new value of property 
-\c{innerColor} whenever the value of this property changes.
+Note that list properties cannot be modified like ordinary JavaScript
+arrays. See the \l {list}{list type documentation} for details.
 
-\code
-    Rectangle {
-        id: rect
-        property color innerColor: "black"
+For details about accessing and manipulating QML properties from C++, see \l {Using QML with C++}.
 
-        onInnerColorChanged: { console.log(rect.innerColor); }
-    }
-\endcode
 
+\section2 Property change signals
+
+Adding a \c property to an item automatically adds a \e {value changed}
+signal handler to the item. To connect to this signal, use a \l {Signal Handlers}{signal handler}
+named with the \c on<Property>Changed syntax, using upper case for the first letter of the
+property name.
+
+For example, the following \c onMyNumberChanged signal handler is automatically called whenever the

+Here, modifying \c buttonText directly modifies the \c textItem.text value; it does not

+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

+
+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.  For example, this will not work:
+use the aliased property directly during creation.  For example, this will not work:
 
 \code
     // Does NOT work
-    property alias innerColor: innerRect.color
-    innerColor: "black"
+    property alias buttonText: textItem.text
+    buttonText: "Some text" // buttonText is not yet defined when this value is set
 \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:

+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:
 
-The syntax for defining a new signal is:
 \code
-signal <name>[([<type> <parameter name>[, ...]])]
+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 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.
+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.)
 
-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.
+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 are three examples of signal declarations:
-\code
-    Item {
-        signal clicked
-        signal hovered()
-        signal performAction(string action, variant actionArgument)
-    }
-\endcode
+Here is an example of a component with a \c say() method that accepts a single \c text argument:
 
-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:
+\snippet doc/src/snippets/declarative/qml-extending-types/methods/app.qml 0
 
-\list
-   \o onClicked
-   \o onHovered
-   \o onPerformAction
-\endlist
+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 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.
+\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
-function <name>([<parameter name>[, ...]]) { <body> }
+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 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.
+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.)
 
-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.
+Here are three examples of signal declarations:
 
-This example adds a new method that behaves like a child:
 \code
 Item {
-    function say(text) {
-        console.log("You said " + text);
-    }
+    signal clicked
+    signal hovered()
+    signal performAction(string action, variant actionArgument)
 }
 \endcode
 
-This may be connected to via QObject::connect() or called directly from C++ using
-QMetaObject::invokeMethod():
+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.
 
-\code
-    QDeclarativeEngine engine;
-    QDeclarativeContext *context = new QDeclarativeContext(engine.rootContext());
-    QDeclarativeComponent component(&engine, QUrl::fromLocalFile("main.qml"));
-    QObject *object = component.create(context);
-    QVariant str("Hello");
-    QMetaObject::invokeMethod(object, "say", Q_ARG(QVariant, str));
-\endcode
-
-Return values of type QVariant are also supported via Q_RETURN_ARG.
-
-\section1 Defining new Components
-\target components
+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:
 
-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 interchangeably
-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.
+\list
+\o onClicked
+\o onHovered
+\o onPerformAction
+\endlist
 
-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.  Note that
-the case of all characters in the <Name> are significant on some filesystems, notably
-UNIX filesystems.  It is recommended that the case of the filename matches the case of
-the component name in QML exactly, regardless of the platform the QML will be deployed to.
+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(). The
+signal is received by \c application.qml through an \c onButtonClicked signal handler:
 
-These QML files automatically become available as new QML element types
-to other QML components and applications in the same directory.

+\o \snippet doc/src/snippets/declarative/qml-extending-types/signals/no-parameters.qml 0
+\endtable
 
-For example, here we show how a component named "Box" is defined and used
-multiple times by an application.
+If the signal has parameters, they are accessible by parameter name in the signal handler.
+In the example below, \c buttonClicked is emitted with \c xPos and \c yPos parameters instead:

-\code
-Rectangle {
-    width: 100; height: 400;

-    Box { x: 0; y: 300 }
-}

+\o \snippet doc/src/snippets/declarative/qml-extending-types/signals/parameters.qml 0
 \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
+\section2 Connecting signals to methods and other signals
 
-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.
+Signal objects have a \c connect() method that can be used to a connect a signal to a method or
+another signal. 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}.
 
-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
+For example, the \c application.qml above could be rewritten as:
 
-As expected, adding additional properties to the root element of Box, makes them
-available externally.  Here we add a "text" property:
+\snippet doc/src/snippets/declarative/qml-extending-types/signals/connectslots.qml 0
 
-\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
+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. The following
+code removes the connection created in \c application.qml above:
+
+\qml
+// application.qml
+Item {
+    ...
+
+    function removeSignal() {
+        button.clicked.disconnect(item.myMethod)
     }
 }
-\endcode
-\endtable
+\endqml
+
+
+\section3 Forwarding signals
+
+The \c connect() method can also connect a signal to other signals. This has the effect
+of "forwarding" a signal: it is automatically emitted whenever the relevant signal is emitted. For
+example, the MouseArea \c onClicked handler in \c Button.qml above could have been replaced with
+a call to \c connect():
+
+\qml
+MouseArea {
+    anchors.fill: parent
+    Component.onCompleted: clicked.connect(item.buttonClicked)
+}
+\endqml
 
-Methods and signals may be added in the same way.
+Whenever the \l MouseArea \c clicked signal is emitted, the \c rect.buttonClicked signal will
+automatically be emitted as well.
 
-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 resilience, 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.

-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 keyboard 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.

+Looking at both \c MyWidget and \c window code, the problem is evident - there

+
+This problem is due to visibility. The \c MyWidget component would like to have

-If more than one \l Item has the \c {Item::focus} property set, the first is selected

-\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

+Note that, since the FocusScope element is not a visual element, the properties
+of its children need to be exposed to the parent item of the FocusScope. Layouts
+and positioning elements will use these visual and styling properties to create

+properly because the FocusScope lacks visual properties of its own. The MyWidget
