    • Detailed Description

    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 RowLayout or a ColumnLayout.

    Items declared as children of a Pane are automatically parented to the Pane's contentItem. Items created dynamically need to be explicitly parented to the contentItem.

    Content Sizing

    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.

    
  Pane {
      ColumnLayout {
          anchors.fill: parent
          CheckBox { text: qsTr("E-mail") }
          CheckBox { text: qsTr("Calendar") }
          CheckBox { text: qsTr("Contacts") }
      }
  }

    Sometimes there might be two items within the pane:

    
  Pane {
      SwipeView {
          // ...
      }
      PageIndicator {
          anchors.horizontalCenter: parent.horizontalCenter
          anchors.bottom: parent.bottom
      }
  }

    In this case, Pane cannot calculate a sensible implicit size. Since we're anchoring the PageIndicator over the SwipeView, we can simply set the content size to the view's implicit size:

    
  Pane {
      contentWidth: view.implicitWidth
      contentHeight: view.implicitHeight

      SwipeView {
          id: view
          // ...
      }
      PageIndicator {
          anchors.horizontalCenter: parent.horizontalCenter
          anchors.bottom: parent.bottom
      }
   }

    See also Item::children and contentData.


    [default] contentData : list<Object>

    This property holds the list of content data.

    The list contains all objects that have been declared in QML as children of the pane.

    Note: Unlike contentChildren, contentData does include non-visual QML objects.

    See also Item::data and contentChildren.


    contentHeight : real

    This property holds the content height. It is used for calculating the total implicit height of the pane.

    For more information, see Content Sizing.

    See also contentWidth.


    contentWidth : real

    This property holds the content width. It is used for calculating the total implicit width of the pane.

    For more information, see Content Sizing.

    See also contentHeight.
