详细描述

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 或 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
    }
 }
