<a name="details"></a>
<h2>Detailed Description</h2>
<p>AnchorAnimation 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-rectangle.html">Rectangle</a>:</p>
<pre class="qml"> import QtQuick 1.0
<span class="type"><a href="qml-item.html">Item</a></span> {
<span class="name">id</span>: <span class="name">container</span>
<span class="name">width</span>: <span class="number">200</span>; <span class="name">height</span>: <span class="number">200</span>
<span class="type"><a href="qml-rectangle.html">Rectangle</a></span> {
<span class="name">id</span>: <span class="name">myRect</span>
<span class="name">width</span>: <span class="number">100</span>; <span class="name">height</span>: <span class="number">100</span>
<span class="name">color</span>: <span class="string">"red"</span>
}
<span class="name">states</span>: <span class="name">State</span> {
<span class="name">name</span>: <span class="string">"reanchored"</span>
<span class="type"><a href="qml-anchorchanges.html">AnchorChanges</a></span> { <span class="name">target</span>: <span class="name">myRect</span>; <span class="name">anchors</span>.right: <span class="name">container</span>.<span class="name">right</span> }
}
<span class="name">transitions</span>: <span class="name">Transition</span> {
<span class="comment">// smoothly reanchor myRect and move into new position</span>
<span class="type">AnchorAnimation</span> { <span class="name">duration</span>: <span class="number">1000</span> }
}
<span class="name">Component</span>.onCompleted: <span class="name">container</span>.<span class="name">state</span> <span class="operator">=</span> <span class="string">"reanchored"</span>
}</pre>
<p>For convenience, when an AnchorAnimation is used in a <a href="qml-transition.html">Transition</a>, it will animate any <a href="qml-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="qmake-variable-reference.html#target">target</a> property.</p>
<p>Like any other animation element, an AnchorAnimation can be applied in a number of ways, including transitions, behaviors and property value sources. The <a href="qdeclarativeanimation.html">QML Animation and Transitions</a> documentation shows a variety of methods for creating animations.</p>
<p><b>See also </b><a href="qdeclarativeanimation.html">QML Animation and Transitions</a> and <a href="qml-anchorchanges.html">AnchorChanges</a>.</p>
