Defines a default animation for a property change. More...
Import Statement: | import QtQuick 2.11 |
A Behavior defines the default animation to be applied whenever a particular property value changes.
For example, the following Behavior defines a NumberAnimation to be run whenever the Rectangle's width
value changes.
When the MouseArea is clicked, the width
is changed, triggering the behavior's animation:
import QtQuick 2.0 Rectangle { id: rect width: 100; height: 100 color: "red" Behavior on width { NumberAnimation { duration: 1000 } } MouseArea { anchors.fill: parent onClicked: rect.width = 50 } }
Note that a property cannot have more than one assigned Behavior. To provide multiple animations within a Behavior, use ParallelAnimation or SequentialAnimation.
If a state change has a Transition that matches the same property as a Behavior, the Transition animation overrides the Behavior for that state change. For general advice on using Behaviors to animate state changes, see Using Qt Quick Behaviors with States.
See also Animation and Transitions in Qt Quick, Behavior example, and Qt QML.
[default] animation : Animation |
This property holds the animation to run when the behavior is triggered.
enabled : bool |
This property holds whether the behavior will be triggered when the tracked property changes value.
By default a Behavior is enabled.
