*
* Currently, GtkApplication handles GTK+ initialization, application
- * uniqueness, provides some basic scriptability by exporting 'actions',
- * implements some standard actions itself (such as 'Quit') and manages
- * a list of toplevel windows whose life-cycle is automatically tied to
- * the life-cycle of your 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 #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 for a GtkApplication, use
+ * gtk_application_set_app_menu(). The #GMenuModel that this function
+ * expects is usually constructed using #GtkBuilder, as seen in the
+ * following example. To specify a menubar that will be shown by
+ * #GtkApplicationWindows, use gtk_application_set_menubar(). Use the base
+ * #GActionMap interface to add actions, to respond to the user
+ * selecting these menu items.
+ *
+ * GTK+ displays these menus as expected, depending on the platform
+ * the application is running on.

+ * GtkApplication optionally registers with a session manager
+ * of the users session (if you set the #GtkApplication: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 gtk_application_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.
