    /// [`Application`][crate::Application] is a high-level API for writing applications.
    ///
    /// It supports many aspects of writing a GTK application in a convenient
    /// fashion, without enforcing a one-size-fits-all model.
    ///
    /// Currently, [`Application`][crate::Application] 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 [`Application`][crate::Application] works fine with plain [`Window`][crate::Window]s, it is
    /// recommended to use it together with [`ApplicationWindow`][crate::ApplicationWindow].
    ///
    /// ## 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 "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.
    ///
    /// It is also possible to provide the menubar manually using
    /// [``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 [``IconTheme::add_resource_path()``][crate::`IconTheme::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
    /// [`Application`][crate::Application] associates an instance of this shortcuts window with
    /// each [`ApplicationWindow`][crate::ApplicationWindow] and sets up the keyboard accelerator
    /// `<kbd>`Control`</kbd>`+`<kbd>`?`</kbd>` to open it. To create a menu item that
    /// displays the shortcuts window, associate the item with the action
    /// `win.show-help-overlay`.
    ///
    /// ## A simple application
    ///
    /// [A simple example](https://gitlab.gnome.org/GNOME/gtk/tree/master/examples/bp/bloatpad.c)
    /// is available in the GTK source code repository
    ///
    /// [`Application`][crate::Application] optionally registers with a session manager of the
    /// users session (if you set the `property::gio::Application::register-session`
    /// property) and offers various functionality related to the session
    /// life-cycle.
    ///
    /// An application can block various ways to end the session with
    /// the [``GtkApplicationExt::inhibit()``][crate::prelude::`GtkApplicationExt::inhibit()`] function. Typical use cases for
    /// this kind of inhibiting are long-running, uninterruptible operations,
    /// such as burning a CD or performing a disk backup. The session
    /// manager may not honor the inhibitor, but it can be expected to
    /// inform the user about the negative consequences of ending the
    /// session while inhibitors are present.
