We add the app-menu and menubar public APIs to GtkApplication while leaving the implementation in GApplication. The actual implementation will be moved soon.

/**

* SECTION:gtkapplication
|
|
* @title: GtkApplication
|
|
* @short_description: Application class
|
|
*
|
|
* #GtkApplication 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, 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.
