ToolBar is a container of application-wide and context sensitive actions and controls, such as navigation buttons and search fields. ToolBar is commonly used as a header 或 footer of an ApplicationWindow .
ToolBar does not provide a layout of its own, but requires you to position its contents, for instance by creating a RowLayout . If only a single item is used within the ToolBar , it will resize to fit the implicit size of its contained item. This makes it particularly suitable for use together with layouts.
ApplicationWindow { visible:true header: ToolBar { RowLayout { anchors.fill: parent ToolButton { text: qsTr("‹") onClicked: stack.pop() } Label { text: "Title" elide: Label.ElideRight horizontalAlignment: Qt.AlignHCenter verticalAlignment: Qt.AlignVCenter Layout.fillWidth: true } ToolButton { text: qsTr("⋮") onClicked: menu.open() } } } StackView { id: stack anchors.fill: parent } }
