+ * uniqueness, 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 #GtkApplicationWindow.
+ *
+ * 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
+ * g_action_group_activate_action(). The same applies to actions
+ * associated with #GtkApplicationWindow and to the 'activate' and
+ * 'open' #GApplication methods.
+ *
+ * To set an application menu on a GtkApplication, use
+ * g_application_set_app_menu(). The #GMenuModel that this function
+ * expects is usually constructed using #GtkBuilder, as seen in the
+ * following example. To set a menubar that will be automatically picked
+ * up by #GApplicationWindows, use g_application_set_menubar(). GTK+
+ * makes these menus appear as expected, depending on the platform
+ * the application is running on.
