Animates changes in anchor values. 更多...

AnchorAnimation is used to animate an anchor change.
In the following snippet we animate the addition of a right anchor to a Rectangle :
import QtQuick 2.0 Item { id: container width: 200; height: 200 Rectangle { id: myRect width: 100; height: 100 color: "red" } states: State { name: "reanchored" AnchorChanges { target: myRect; anchors.right: container.right } } transitions: Transition { // smoothly reanchor myRect and move into new position AnchorAnimation { duration: 1000 } } Component.onCompleted: container.state = "reanchored" }
当 AnchorAnimation is used in a Transition , it will animate any AnchorChanges that have occurred during the state change. This can be overridden by setting a specific target item using the AnchorChanges.target 特性。
注意： AnchorAnimation can only be used in a Transition and in conjunction with an AnchorChange. It cannot be used in behaviors and other types of animations.

Specifies the easing curve used for the animation
To specify an easing curve you need to specify at least the type. For some curves you can also specify amplitude, period and/or overshoot. The default easing curve is Linear.
AnchorAnimation { easing.type: Easing.InOutQuad }
见 PropertyAnimation::easing.type documentation for information about the different types of easing curves.
The items to reanchor.
If no targets are specified all AnchorChanges will be animated by the AnchorAnimation .
