    /// [`Application`][crate::Application].
    ///
    /// Notably, [`ApplicationWindow`][crate::ApplicationWindow] can handle an application menubar.
    ///
    /// This class implements the `GActionGroup` and `GActionMap` interfaces,
    /// to let you add window-specific actions that will be exported by the
    /// associated [`Application`][crate::Application], together with its application-wide
    /// actions. Window-specific actions are prefixed with the “win.”
    /// prefix and application-wide actions are prefixed with the “app.”
    /// prefix. Actions must be addressed with the prefixed name when
    /// referring to them from a `GMenuModel`.
    ///
    /// Note that widgets that are placed inside a [`ApplicationWindow`][crate::ApplicationWindow]
    /// can also activate these actions, if they implement the
    /// [`Actionable`][crate::Actionable] interface.
    ///
    /// The settings `property::Settings::gtk-shell-shows-app-menu` and
    /// `property::Settings::gtk-shell-shows-menubar` tell GTK whether the
    /// desktop environment is showing the application menu and menubar
    /// models outside the application as part of the desktop shell.
    /// For instance, on OS X, both menus will be displayed remotely;
    /// on Windows neither will be.
    ///
    /// If the desktop environment does not display the menubar, then
    /// [`ApplicationWindow`][crate::ApplicationWindow] will automatically show a menubar for it.
    /// This behaviour can be overridden with the
    /// `property::ApplicationWindow::show-menubar` property. If the
    /// desktop environment does not display the application menu, then
    /// it will automatically be included in the menubar or in the windows
    /// client-side decorations.
    ///
    /// See [`PopoverMenu`][crate::PopoverMenu] for information about the XML language
    /// used by [`Builder`][crate::Builder] for menu models.
