<div class="descr"> <a name="details"></a>
<p class="centerAlign"><img src="images/qml-positioners-example.png" alt="" /></p><p><i>Positioners</i> is a collection of small QML examples relating to positioners. Each example is a small QML file emphasizing a particular type or feature. For more information, visit <a href="qtquick-positioning-topic.html">Important Concepts In Qt Quick - Positioning</a>.</p>
<a name="running-the-example"></a>
<h2 id="running-the-example">Running the Example</h2>
<p>To run the example from Qt Creator, open the <b>Welcome</b> mode and select the example from <b>Examples</b>. For more information, visit Building and Running an Example.</p>
<a name="transitions"></a>
<h2 id="transitions">Transitions</h2>
<p><i>Transitions</i> shows animated transitions when showing or hiding items in a positioner. It consists of a scene populated with items in a variety of positioners: <a href="qml-qtquick-column.html">Column</a>, <a href="qml-qtquick-row.html">Row</a>, <a href="qml-qtquick-grid.html">Grid</a>, and <a href="qml-qtquick-flow.html">Flow</a>. Each positioner has animations described as Transitions.</p>
<pre class="qml">
move: Transition {
NumberAnimation { properties: "x,y"; easing.type: Easing.OutBounce }
}
</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">
add: Transition {
NumberAnimation { properties: "x,y"; easing.type: Easing.OutBounce }
}
</pre>
<p>The add transition specifies how items will appear when they are added to a positioner.</p>
<pre class="qml">
populate: Transition {
NumberAnimation { properties: "x,y"; from: 200; duration: 100; easing.type: Easing.OutBounce }
}
</pre>
<p>The populate transition specifies how items will appear when their parent positioner is first created.</p>
<a name="attached-properties"></a>
<h2 id="attached-properties">Attached Properties</h2>
<p><i>Attached Properties</i> shows how the Positioner attached property can be used to determine where an item is within a positioner.</p>
<pre class="qml">
Rectangle {
id: green
color: "#80c342"
width: 100 * page.ratio
height: 100 * page.ratio
Text {
anchors.left: parent.right
anchors.leftMargin: 20
anchors.verticalCenter: parent.verticalCenter
text: "Index: " + parent.Positioner.index
+ (parent.Positioner.isFirstItem ? " (First)" : "")
+ (parent.Positioner.isLastItem ? " (Last)" : "")
}
// When mouse is clicked, display the values of the positioner
MouseArea {

}
}
