详细描述

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
    }
}
