## 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`.

As mentioned in Event Handling, Pane does not let click and touch events through to items beneath it. If wheelEnabled is `true`, the same applies to mouse wheel events.

## 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
         }
      }

If the contentItem has no implicit size and only one child, Pane will use the implicit size of that child. For example, in the following code, the Pane assumes the size of the Rectangle:

     Pane {
         Item {
             Rectangle {
                 implicitWidth: 200
                 implicitHeight: 200
                 color: "salmon"
             }
         }
     }

## Property Documentation

contentChildren : list<Item>

This property holds the list of content children.

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

Note: Unlike `contentData`, `contentChildren` does not include non-visual QML objects.

See also Item::children and contentData.

[default] contentData : list<QtObject>

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.
