/*!
    \qmltype Menu
    \inherits QtObject
//! \instantiates QQuickPlatformMenu
    \inqmlmodule Qt.labs.platform
    \since 5.8
    \brief A native menu.

    The Menu type provides a QML API for native platform menu popups.

    \image qtlabsplatform-menu.png

    Menu can be used in a \l MenuBar, or as a stand-alone context menu.
    The following example shows how to open a context menu on right mouse
    click:

    \code
    MouseArea {
        anchors.fill: parent
        acceptedButtons: Qt.RightButton
        onClicked: zoomMenu.open()
    }

    Menu {
        id: zoomMenu

        MenuItem {
            text: qsTr("Zoom In")
            shortcut: StandardKey.ZoomIn
            onTriggered: zoomIn()
        }

        MenuItem {
            text: qsTr("Zoom Out")
            shortcut: StandardKey.ZoomOut
            onTriggered: zoomOut()
        }
    }
    \endcode

    \section2 Submenus

    To create submenus, declare a Menu as a child of another Menu:

    \qml
    Menu {
        title: qsTr("Edit")

        Menu {
            title: qsTr("Advanced")

            MenuItem {
                text: qsTr("Auto-indent Selection")
                onTriggered: autoIndentSelection()
            }

            MenuItem {
                text: qsTr("Rewrap Paragraph")
                onTriggered: rewrapParagraph()
            }
        }
    }
    \endqml

    \section2 Dynamically Generating Menu Items

    It is possible to dynamically generate menu items. One of the easiest ways
    to do so is with \l[QtQml]{Instantiator}. For example, to implement a
    "Recent Files" submenu, where the items are based on a list of files stored
    in settings, the following code could be used:

    \qml
    Menu {
        title: qsTr("File")

        Menu {
            id: recentFilesSubMenu
            title: qsTr("Recent Files")
            enabled: recentFilesInstantiator.count > 0

            Instantiator {
                id: recentFilesInstantiator
                model: settings.recentFiles
                delegate: MenuItem {
                    text: settings.displayableFilePath(modelData)
                    onTriggered: loadFile(modelData)
                }

                onObjectAdded: recentFilesSubMenu.insertItem(index, object)
                onObjectRemoved: recentFilesSubMenu.removeItem(object)
            }

            MenuSeparator {}

            MenuItem {
                text: qsTr("Clear Recent Files")
                onTriggered: settings.clearRecentFiles()
            }
        }
    }
    \endqml

    \section2 Availability

    A native platform menu is currently available on the following platforms:

    \list
    \li macOS
    \li iOS
    \li Android
    \li Linux (only available as a stand-alone context menu when running with the GTK+ platform theme)
    \endlist
