\inherits Animation
\brief The PropertyAction element allows immediate property changes during animation.
- PropertyAction is used to specify an immediate property change
- during an animation. The property change is not animated.
+ PropertyAction is used to specify an immediate property change during an
+ animation. The property change is not animated.
- For example, to explicitly set \c {theImage.smooth = true} during a \l Transition:
- \code
- transitions: Transition {
- ...
- PropertyAction { target: theImage; property: "smooth"; value: true }
- ...
- }
- \endcode
+ It is useful for setting non-animated property values during an animation.
- Or, to set \c theWebView.url to the value set for the destination state:
- \code
+ For example, here is a SequentialAnimation that sets the image's
+ \l {Image::}{smooth} property to \c true, animates the width of the image,
+ then sets \l {Image::}{smooth} back to \c false:
+
+ \snippet doc/src/snippets/declarative/propertyaction.qml standalone
+
+ PropertyAction is also useful for setting the exact point at which a property
+ change should occur during a \l Transition. For example, if PropertyChanges
+ was used in a \l State to rotate an item around a particular
+ \l {Item::}{transformOrigin}, it might be implemented like this:
+
+ \snippet doc/src/snippets/declarative/propertyaction.qml transition
+
+ However, with this code, the \c transformOrigin is not set until \e after
+ the animation, as a \l State is taken to define the values at the \e end of
+ a transition. The animation would rotate at the default \c transformOrigin,
+ then jump to \c Item.BottomRight. To fix this, insert a PropertyChanges
+ before the RotationAnimation begins:
+
+ \qml
transitions: Transition {
- ...
- PropertyAction { target: theWebView; property: "url" }
- ...
+ SequentialAnimation {
+ PropertyAction { target: rect; property: "transformOrigin" }
+ RotationAnimation { ... }
+ }
}
- \endcode
-
+ \endqml
+
+ This immediately sets the \c transformOrigin property to the value defined
+ in the end state of the \l Transition (i.e. the value defined in the
+ PropertyChanges object) so that the rotation animation begins with the
+ correct transform origin.

\brief The PropertyChanges element describes new property bindings or values for a state.
- PropertyChanges provides a state change that modifies the properties of an item.
+ PropertyChanges is used to define the property values or bindings in a
+ \l State. This enables an item's property values to be changed when it
+ \l {QML States}{changes between states}.
- Here is a property change that modifies the text and color of a \l Text element
- when it is clicked:
+ To create a PropertyChanges object, specify the \l target item whose
+ properties are to be modified, and define the new property values or
+ bindings. For example:
- \qml
- Text {
- id: myText
- width: 100; height: 100
- text: "Hello"
- color: "blue"
-
- states: State {
- name: "myState"
-
- PropertyChanges {
- target: myText
- text: "Goodbye"
- color: "red"
- }
- }
-
- MouseArea { anchors.fill: parent; onClicked: myText.state = 'myState' }
- }
- \endqml
-
- By default, PropertyChanges will establish new bindings where appropriate.
- For example, the following creates a new binding for myItem's \c height property.
-
- \qml
- PropertyChanges {
- target: myItem
- height: parent.height
- }
- \endqml
-
- If you don't want a binding to be established (and instead just want to assign
- the value of the binding at the time the state is entered),
- you should set the PropertyChange's \l{PropertyChanges::explicit}{explicit}
+ \snippet doc/src/snippets/declarative/propertychanges.qml import
+ \codeline
+ \snippet doc/src/snippets/declarative/propertychanges.qml 0
+
+ When the mouse is pressed, the \l Rectangle changes to the \e resized
+ state. In this state, the PropertyChanges object sets the rectangle's
+ color to blue and the \c height value to that of \c container.height.
+
+ Note this automatically binds \c rect.height to \c container.height
+ in the \e resized state. If a property binding should not be
+ established, and the height should just be set to the value of
+ \c container.height at the time of the state change, set the \l explicit
property to \c true.

- State-specific script for signal handlers can also be specified:
+
+ A PropertyChanges object can also override the default signal handler
+ for an object to implement a signal handler specific to the new state:

- You can reset a property in a state change by assigning \c undefined. In the following
- example we reset \c theText's width when we enter state1. This will give the text its
- natural width (which is the whole string on one line).
+ \note PropertyChanges can be used to change anchor margins, but not other anchor
+ values; use AnchorChanges for this instead. Similarly, to change an \l Item's
+ \l {Item::}{parent} value, use ParentChanges instead.

- Rectangle {
- width: 640
- height: 480
- Text {
- id: theText
- width: 50
- wrapMode: Text.WordWrap
- text: "a text string that is longer than 50 pixels"
- }
- states: State {
- name: "state1"
- PropertyChanges {
- target: theText
- width: undefined
- }
- }
- }
- \endqml
+ \section2 Resetting property values
- Anchor margins should be changed with PropertyChanges, but other anchor changes or changes to
- an Item's parent should be done using the associated change elements
- (ParentChange and AnchorChanges, respectively).
+ The \c undefined value can be used to reset the property value for a state.
+ In the following example, when \c theText changes to the \e widerText
+ state, its \c width property is reset, giving the text its natural width
+ and displaying the whole string on a single line.
+
+ \snippet doc/src/snippets/declarative/propertychanges.qml reset
+
+
+ \section2 Immediate property changes in transitions
+
+ When \l Transitions are used to animate state changes, they animate
+ properties from their values in the current state to those defined in the
+ new state (as defined by PropertyChanges objects). However,
+ it is sometimes desirable to set a property value \e immediately during a
+ \l Transition, without animation; in these cases, the PropertyAction
+ element can be used to force an immediate property change.
+
+ See the PropertyAction documentation for more details.
