<a name="details"></a>
<h2 id="details">Detailed Description</h2>
</p>
<p>Flipable is an item that can be visibly &quot;flipped&quot; between its front and back sides, like a card. It may used together with <a href="qml-qtquick-rotation.html">Rotation</a>, <a href="qml-qtquick-state.html">State</a> and <a href="qmlexampletoggleswitch.html#transition">Transition</a> types to produce a flipping effect.</p>
<p>The <a href="qml-qtquick-flipable.html#front-prop">front</a> and <a href="qml-qtquick-flipable.html#back-prop">back</a> properties are used to hold the items that are shown respectively on the front and back sides of the flipable item.</p>
<a name="example-usage"></a>
<h2 id="example-usage">Example Usage</h2>
<p>The following example shows a Flipable item that flips whenever it is clicked, rotating about the y-axis.</p>
<p>This flipable item has a <code>flipped</code> boolean property that is toggled whenever the <a href="qml-qtquick-mousearea.html">MouseArea</a> within the flipable is clicked. When <code>flipped</code> is true, the item changes to the &quot;back&quot; state; in this state, the <code>angle</code> of the <a href="qml-qtquick-rotation.html">Rotation</a> item is changed to 180 degrees to produce the flipping effect. When <code>flipped</code> is false, the item reverts to the default state, in which the <code>angle</code> value is 0.</p>
