void gdk_display_notify_startup_complete ( GdkDisplay* display, const char* startup_id )
Indicates to the GUI environment that the application has finished loading, using a given identifier.
GTK will call this function automatically for Gtk.Window with custom startup-notification identifier unless Gtk.Window.set_auto_startup_notification is called to disable that feature.
Deprecated since: 4.10
gdk_toplevel_set_startup_id() is sufficient.
