Detailed Description
The AnchorChanges type is used to modify the anchors of an item in a State.
AnchorChanges cannot be used to modify the margins on an item. For this, use PropertyChanges instead.
In the following example we change the top and bottom anchors of an item using AnchorChanges, and the top and bottom anchor margins using PropertyChanges:
import QtQuick 2.0 Rectangle { id: window width: 120; height: 120 color: "black" Rectangle { id: myRect; width: 50; height: 50; color: "red" } states: State { name: "reanchored" AnchorChanges { target: myRect anchors.top: window.top anchors.bottom: window.bottom } PropertyChanges { target: myRect anchors.topMargin: 10 anchors.bottomMargin: 10 } } MouseArea { anchors.fill: parent; onClicked: window.state = "reanchored" } }
AnchorChanges can be animated using AnchorAnimation.
//animate our anchor changes Transition { AnchorAnimation {} }
Changes to anchor margins can be animated using NumberAnimation.
For more information on anchors see Anchor Layouts.
Property Documentation

AnchorChanges { target: myItem anchors.left: undefined //remove myItem's left anchor anchors.right: otherItem.right }
