    /// [`Application`][crate::Application] is a class that handles many important aspects
    /// of a GTK+ application in a convenient fashion, without enforcing
    /// a one-size-fits-all application model.
    ///
    /// Currently, GtkApplication handles GTK+ initialization, application
    /// uniqueness, session management, provides some basic scriptability and
    /// desktop shell integration by exporting actions and menus and manages a
    /// list of toplevel windows whose life-cycle is automatically tied to the
    /// life-cycle of your application.
    ///
    /// While GtkApplication works fine with plain `GtkWindows`, it is recommended
    /// to use it together with [`ApplicationWindow`][crate::ApplicationWindow].
    ///
    /// When GDK threads are enabled, GtkApplication will acquire the GDK
    /// lock when invoking actions that arrive from other processes. The GDK
    /// lock is not touched for local action invocations. In order to have
    /// actions invoked in a predictable context it is therefore recommended
    /// that the GDK lock be held while invoking actions locally with
    /// [`ActionGroupExtManual::activate_action()`][crate::gio::prelude::ActionGroupExtManual::activate_action()]. The same applies to actions
    /// associated with [`ApplicationWindow`][crate::ApplicationWindow] and to the “activate” and
    /// “open” [`gio::Application`][crate::gio::Application] methods.
    ///
    /// ## Automatic resources ## {`automatic`-resources}
    ///
    /// [`Application`][crate::Application] will automatically load menus from the [`Builder`][crate::Builder]
    /// resource located at "gtk/menus.ui", relative to the application's
    /// resource base path (see [`ApplicationExtManual::set_resource_base_path()`][crate::gio::prelude::ApplicationExtManual::set_resource_base_path()]). The
    /// menu with the ID "app-menu" is taken as the application's app menu
    /// and the menu with the ID "menubar" is taken as the application's
    /// menubar. Additional menus (most interesting submenus) can be named
    /// and accessed via [`GtkApplicationExt::menu_by_id()`][crate::prelude::GtkApplicationExt::menu_by_id()] which allows for
    /// dynamic population of a part of the menu structure.
    ///
    /// If the resources "gtk/menus-appmenu.ui" or "gtk/menus-traditional.ui" are
    /// present then these files will be used in preference, depending on the value
    /// of [`GtkApplicationExt::prefers_app_menu()`][crate::prelude::GtkApplicationExt::prefers_app_menu()]. If the resource "gtk/menus-common.ui"
    /// is present it will be loaded as well. This is useful for storing items that
    /// are referenced from both "gtk/menus-appmenu.ui" and
    /// "gtk/menus-traditional.ui".
    ///
    /// It is also possible to provide the menus manually using
    /// [`GtkApplicationExt::set_app_menu()`][crate::prelude::GtkApplicationExt::set_app_menu()] and [`GtkApplicationExt::set_menubar()`][crate::prelude::GtkApplicationExt::set_menubar()].
    ///
    /// [`Application`][crate::Application] will also automatically setup an icon search path for
    /// the default icon theme by appending "icons" to the resource base
    /// path. This allows your application to easily store its icons as
    /// resources. See [`IconThemeExt::add_resource_path()`][crate::prelude::IconThemeExt::add_resource_path()] for more
    /// information.
    ///
    /// If there is a resource located at "gtk/help-overlay.ui" which
    /// defines a [`ShortcutsWindow`][crate::ShortcutsWindow] with ID "help_overlay" then GtkApplication
    /// associates an instance of this shortcuts window with each
    /// [`ApplicationWindow`][crate::ApplicationWindow] and sets up keyboard accelerators (Control-F1
    /// and Control-?) to open it. To create a menu item that displays the
    /// shortcuts window, associate the item with the action win.show-help-overlay.

    /// An application can block various ways to end the session with
