<a name="details"></a> <h2>Detailed Description</h2> <p>Flipable is an item that can be visibly "flipped" between its front and back sides, like a card. It is used together with <a href="qml-rotation.html">Rotation</a>, <a href="qml-state.html">State</a> and <a href="qml-transition.html">Transition</a> elements to produce a flipping effect.</p> <p>The <a href="qml-flipable.html#front-prop">front</a> and <a href="qml-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>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 <tt>flipped</tt> boolean property that is toggled whenever the <a href="qml-mousearea.html">MouseArea</a> within the flipable is clicked. When <tt>flipped</tt> is true, the item changes to the "back" state; in this state, the <tt>angle</tt> of the <a href="qml-rotation.html">Rotation</a> item is changed to 180 degrees to produce the flipping effect. When <tt>flipped</tt> is false, the item reverts to the default state, in which the <tt>angle</tt> value is 0.</p> <pre class="qml"> import QtQuick 1.0 <span class="type">Flipable</span> { <span class="name">id</span>: <span class="name">flipable</span> <span class="name">width</span>: <span class="number">240</span> <span class="name">height</span>: <span class="number">240</span> property <span class="type"><a href="qml-bool.html">bool</a></span> <span class="name">flipped</span>: <span class="number">false</span> <span class="name">front</span>: <span class="name">Image</span> { <span class="name">source</span>: <span class="string">"front.png"</span>; <span class="name">anchors</span>.centerIn: <span class="name">parent</span> } <span class="name">back</span>: <span class="name">Image</span> { <span class="name">source</span>: <span class="string">"back.png"</span>; <span class="name">anchors</span>.centerIn: <span class="name">parent</span> } <span class="name">transform</span>: <span class="name">Rotation</span> { <span class="name">id</span>: <span class="name">rotation</span> <span class="name">origin</span>.x: <span class="name">flipable</span>.<span class="name">width</span><span class="operator">/</span><span class="number">2</span> <span class="name">origin</span>.y: <span class="name">flipable</span>.<span class="name">height</span><span class="operator">/</span><span class="number">2</span> <span class="name">axis</span>.x: <span class="number">0</span>; <span class="name">axis</span>.y: <span class="number">1</span>; <span class="name">axis</span>.z: <span class="number">0</span> <span class="comment">// set axis.y to 1 to rotate around y-axis</span> <span class="name">angle</span>: <span class="number">0</span> <span class="comment">// the default angle</span> } <span class="name">states</span>: <span class="name">State</span> { <span class="name">name</span>: <span class="string">"back"</span> <span class="type"><a href="qml-propertychanges.html">PropertyChanges</a></span> { <span class="name">target</span>: <span class="name">rotation</span>; <span class="name">angle</span>: <span class="number">180</span> } <span class="name">when</span>: <span class="name">flipable</span>.<span class="name">flipped</span> } <span class="name">transitions</span>: <span class="name">Transition</span> { <span class="type"><a href="qml-numberanimation.html">NumberAnimation</a></span> { <span class="name">target</span>: <span class="name">rotation</span>; <span class="name">property</span>: <span class="string">"angle"</span>; <span class="name">duration</span>: <span class="number">4000</span> } } <span class="type"><a href="qml-mousearea.html">MouseArea</a></span> { <span class="name">anchors</span>.fill: <span class="name">parent</span> <span class="name">onClicked</span>: <span class="name">flipable</span>.<span class="name">flipped</span> <span class="operator">=</span> !<span class="name">flipable</span>.<span class="name">flipped</span> } }</pre> <p class="centerAlign"><img src="images/flipable.gif" alt="" /></p><p>The <a href="qml-transition.html">Transition</a> creates the animation that changes the angle over four seconds.
