<!-- $$$Pane-description -->
<a name="details"></a>
<h2 id="details">Detailed Description</h2>
<p>Pane provides a background color that matches with the application style and theme. Pane does not provide a layout of its own, but requires you to position its contents, for instance by creating a <a href="../qtquick/qml-qtquick-layouts-rowlayout.html">RowLayout</a> or a <a href="../qtquick/qml-qtquick-layouts-columnlayout.html">ColumnLayout</a>.</p>
<p>Items declared as children of a Pane are automatically parented to the Pane's <a href="qml-qtquick-controls2-control.html#contentItem-prop">contentItem</a>. Items created dynamically need to be explicitly parented to the contentItem.</p>
<a name="content-sizing"></a>
<h2 id="content-sizing">Content Sizing</h2>
<p>If only a single item is used within a Pane, it will resize to fit the implicit size of its contained item. This makes it particularly suitable for use together with layouts.</p>
<p class="centerAlign"><img src="images/qtquickcontrols2-pane.png" alt="" /></p><pre class="qml">

  <span class="type"><a href="qml-qtquick-controls2-pane.html">Pane</a></span> {
      <span class="type"><a href="../qtquick/qml-qtquick-layouts-columnlayout.html">ColumnLayout</a></span> {
          <span class="name">anchors</span>.fill: <span class="name">parent</span>
          <span class="type"><a href="qml-qtquick-controls2-checkbox.html">CheckBox</a></span> { <span class="name">text</span>: <span class="name">qsTr</span>(<span class="string">&quot;E-mail&quot;</span>) }
          <span class="type"><a href="qml-qtquick-controls2-checkbox.html">CheckBox</a></span> { <span class="name">text</span>: <span class="name">qsTr</span>(<span class="string">&quot;Calendar&quot;</span>) }
          <span class="type"><a href="qml-qtquick-controls2-checkbox.html">CheckBox</a></span> { <span class="name">text</span>: <span class="name">qsTr</span>(<span class="string">&quot;Contacts&quot;</span>) }
      }
  }

</pre>
<p>Sometimes there might be two items within the pane:</p>
<pre class="cpp">

  Pane {
      SwipeView {
          <span class="comment">// ...</span>
      }
      PageIndicator {
          anchors<span class="operator">.</span>horizontalCenter: parent<span class="operator">.</span>horizontalCenter
          anchors<span class="operator">.</span>bottom: parent<span class="operator">.</span>bottom
      }
  }

</pre>
<p>In this case, Pane cannot calculate a sensible implicit size. Since we're anchoring the <a href="qml-qtquick-controls2-pageindicator.html">PageIndicator</a> over the <a href="qml-qtquick-controls2-swipeview.html">SwipeView</a>, we can simply set the content size to the view's implicit size:</p>
<pre class="cpp">

  Pane {
      contentWidth: view<span class="operator">.</span>implicitWidth
      contentHeight: view<span class="operator">.</span>implicitHeight

      SwipeView {
          id: view
          <span class="comment">// ...</span>
      }
      PageIndicator {
          anchors<span class="operator">.</span>horizontalCenter: parent<span class="operator">.</span>horizontalCenter
          anchors<span class="operator">.</span>bottom: parent<span class="operator">.</span>bottom
      }
   }

</pre>
