<h2 id="details">Detailed Description</h2>
<p><a href="qml-qtquick-anchoranimation.html">AnchorAnimation</a> is used to animate an anchor change.</p>
<p>In the following snippet we animate the addition of a right anchor to a <a href="qml-qtquick-rectangle.html">Rectangle</a>:</p>
<pre class="qml">
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"
}
</pre>
<p>When an <a href="qml-qtquick-anchoranimation.html">AnchorAnimation</a> is used in a <a href="qmlexampletoggleswitch.html#transition">Transition</a>, it will animate any <a href="qml-qtquick-anchorchanges.html">AnchorChanges</a> that have occurred during the state change. This can be overridden by setting a specific target item using the <a href="qml-qtquick-anchorchanges.html#target-prop">AnchorChanges.target</a> property.</p>
<p><b>Note: </b><a href="qml-qtquick-anchoranimation.html">AnchorAnimation</a> can only be used in a <a href="qmlexampletoggleswitch.html#transition">Transition</a> and in conjunction with an AnchorChange. It cannot be used in behaviors and other types of animations.</p><p><b>See also </b><a href="qtquick-statesanimations-animations.html">Animation and Transitions in Qt Quick</a> and <a href="qml-qtquick-anchorchanges.html">AnchorChanges</a>.</p>
