## Detailed Description

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

     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"
     }

When an 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 property.

Note: 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.

See also Animation and Transitions in Qt Quick and AnchorChanges.

## Property Documentation

duration : int

This property holds the duration of the animation, in milliseconds.

The default value is 250.

easing group
easing.amplitude : real
easing.overshoot : real
easing.period : real
easing.type : enumeration

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 }

See the PropertyAnimation::easing.type documentation for information about the different types of easing curves.

[read-only] targets : list<Item>

The items to reanchor.

If no targets are specified all AnchorChanges will be animated by the AnchorAnimation.
