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"
}
}
