<!-- $$$StackLayout-brief -->
<p>The <a href="qml-qtquick-layouts-stacklayout.html">StackLayout</a> class provides a stack of items where only one item is visible at a time. <a href="#details">More...</a></p>

<h2 id="details">Detailed Description</h2>
<p>The current visible item can be modified by setting the <a href="qml-qtquick-layouts-stacklayout.html#currentIndex-prop">currentIndex</a> property. The index corresponds to the order of the <a href="qml-qtquick-layouts-stacklayout.html">StackLayout</a>'s children.</p>
<p>In contrast to most other layouts, child Items' <a href="qml-qtquick-layouts-layout.html#fillWidth-attached-prop">Layout.fillWidth</a> and <a href="qml-qtquick-layouts-layout.html#fillHeight-attached-prop">Layout.fillHeight</a> properties default to <code>true</code>. As a consequence, child items are by default filled to match the size of the <a href="qml-qtquick-layouts-stacklayout.html">StackLayout</a> as long as their <a href="qml-qtquick-layouts-layout.html#maximumWidth-attached-prop">Layout.maximumWidth</a> or <a href="qml-qtquick-layouts-layout.html#maximumHeight-attached-prop">Layout.maximumHeight</a> does not prevent it.</p>
<p>Items are added to the layout by reparenting the item to the layout. Similarly, removal is done by reparenting the item from the layout. Both of these operations will affect the layout's <a href="qml-qtquick-layouts-stacklayout.html#count-prop">count</a> property.</p>
<p>The following code will create a <a href="qml-qtquick-layouts-stacklayout.html">StackLayout</a> where only the 'plum' rectangle is visible.</p>
<pre class="cpp">

  StackLayout {
      id: layout
      anchors<span class="operator">.</span>fill: parent
      currentIndex: <span class="number">1</span>
      Rectangle {
          color: <span class="char">'teal'</span>
          implicitWidth: <span class="number">200</span>
          implicitHeight: <span class="number">200</span>
      }
      Rectangle {
          color: <span class="char">'plum'</span>
          implicitWidth: <span class="number">300</span>
          implicitHeight: <span class="number">200</span>
      }
  }
