    /// [`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.
    ///
    /// Note that automatic resource loading uses the resource base path
    /// that is set at construction time and will not work if the resource
    /// base path is changed at a later time.
    ///
    /// 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/main/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 [`register-session`][struct@crate::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.

    ///
    ///

    ///  Emitted when the session manager is about to end the session.
    ///
    /// This signal is only emitted if [`register-session`][struct@crate::Application#register-session]
    /// is `TRUE`. Applications can connect to this signal and call
    /// [`GtkApplicationExt::inhibit()`][crate::prelude::GtkApplicationExt::inhibit()] with `GTK_APPLICATION_INHIBIT_LOGOUT`
    /// to delay the end of the session until state has been saved.
    ///
    ///
    ///
    ///
    /// #### `window-added`
    ///  Emitted when a [`Window`][crate::Window] is added to `application` through
    /// [`GtkApplicationExt::add_window()`][crate::prelude::GtkApplicationExt::add_window()].
    ///
    ///
    ///
    ///
    /// #### `window-removed`

    ///
    ///
    /// <details><summary><h4>Application</h4></summary>
    ///
    ///
    /// #### `activate`
    ///  The ::activate signal is emitted on the primary instance when an
    /// activation occurs. See g_application_activate().
    ///
    ///
    ///
    ///
    /// #### `command-line`
    ///  The ::command-line signal is emitted on the primary instance when
    /// a commandline is not handled locally. See g_application_run() and
    /// the #GApplicationCommandLine documentation for more information.
    ///
    ///
    ///
    ///
    /// #### `handle-local-options`
    ///  The ::handle-local-options signal is emitted on the local instance
    /// after the parsing of the commandline options has occurred.
    ///
    /// You can add options to be recognised during commandline option
    /// parsing using g_application_add_main_option_entries() and
    /// g_application_add_option_group().
    ///
    /// Signal handlers can inspect @options (along with values pointed to
    /// from the @arg_data of an installed #GOptionEntrys) in order to
    /// decide to perform certain actions, including direct local handling
    /// (which may be useful for options like --version).
    ///
    /// In the event that the application is marked
    /// [`gio::ApplicationFlags::HANDLES_COMMAND_LINE`][crate::gio::ApplicationFlags::HANDLES_COMMAND_LINE] the "normal processing" will
    /// send the @options dictionary to the primary instance where it can be
    /// read with g_application_command_line_get_options_dict().  The signal
    /// handler can modify the dictionary before returning, and the
    /// modified dictionary will be sent.
    ///
    /// In the event that [`gio::ApplicationFlags::HANDLES_COMMAND_LINE`][crate::gio::ApplicationFlags::HANDLES_COMMAND_LINE] is not set,
    /// "normal processing" will treat the remaining uncollected command
    /// line arguments as filenames or URIs.  If there are no arguments,
    /// the application is activated by g_application_activate().  One or
    /// more arguments results in a call to g_application_open().
    ///
    /// If you want to handle the local commandline arguments for yourself
    /// by converting them to calls to g_application_open() or
    /// g_action_group_activate_action() then you must be sure to register
    /// the application first.  You should probably not call
    /// g_application_activate() for yourself, however: just return -1 and
    /// allow the default handler to do it for you.  This will ensure that
    /// the `--gapplication-service` switch works properly (i.e. no activation
    /// in that case).
    ///
    /// Note that this signal is emitted from the default implementation of
    /// local_command_line().  If you override that function and don't
    /// chain up then this signal will never be emitted.
    ///
    /// You can override local_command_line() if you need more powerful
    /// capabilities than what is provided here, but this should not
    /// normally be required.
    ///
    ///
    ///
    ///
    /// #### `name-lost`
    ///  The ::name-lost signal is emitted only on the registered primary instance
    /// when a new instance has taken over. This can only happen if the application
    /// is using the [`gio::ApplicationFlags::ALLOW_REPLACEMENT`][crate::gio::ApplicationFlags::ALLOW_REPLACEMENT] flag.
    ///
    /// The default handler for this signal calls g_application_quit().
    ///
    ///
    ///
    ///
    /// #### `open`
    ///  The ::open signal is emitted on the primary instance when there are
    /// files to open. See g_application_open() for more information.
    ///
    ///
    ///
    ///
    /// #### `shutdown`
    ///  The ::shutdown signal is emitted only on the registered primary instance
    /// immediately after the main loop terminates.
    ///
    ///
    ///
    ///
    /// #### `startup`
    ///  The ::startup signal is emitted on the primary instance immediately
    /// after registration. See g_application_register().
