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 intead.

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.
