<p>This is a collection of QML Positioner examples.<p class="centerAlign"><img src="images/qml-positioners-example.png" alt="" /></p><p>This is a collection of small QML examples relating to positioners. Each example is a small QML file emphasizing a particular type or feature.</p>
<p>Transitions shows animated transitions when showing or hiding items in a positioner. It consists of a scene populated with items in a variety of positioners: Column, Row, Grid and Flow. Each positioner has animations described as Transitions.</p>
<pre class="qml"><span class="name">move</span>: <span class="name">Transition</span> {
<span class="type"><a href="qml-qtquick-numberanimation.html">NumberAnimation</a></span> { <span class="name">properties</span>: <span class="string">"x,y"</span>; <span class="name">easing</span>.type: <span class="name">Easing</span>.<span class="name">OutBounce</span> }
}</pre>
<p>The move transition specifies how items inside a positioner will animate when they are displaced by the appearance or disappearance of other items.</p>
<pre class="qml"><span class="name">add</span>: <span class="name">Transition</span> {
<span class="type"><a href="qml-qtquick-numberanimation.html">NumberAnimation</a></span> { <span class="name">properties</span>: <span class="string">"x,y"</span>; <span class="name">easing</span>.type: <span class="name">Easing</span>.<span class="name">OutBounce</span> }
}</pre>
<p>The add transition specifies how items will appear when they are added to a positioner.</p>
<pre class="qml"><span class="name">populate</span>: <span class="name">Transition</span> {
<span class="type"><a href="qml-qtquick-numberanimation.html">NumberAnimation</a></span> { <span class="name">properties</span>: <span class="string">"x,y"</span>; <span class="name">from</span>: <span class="number">200</span>; <span class="name">duration</span>: <span class="number">1500</span>; <span class="name">easing</span>.type: <span class="name">Easing</span>.<span class="name">OutBounce</span> }
}</pre>
<p>The populate transition specifies how items will appear when their parent positioner is first created.</p>
<p>Attached Properties shows how the Positioner attached property can be used to determine where an item is within a positioner.</p>
