void gtk_action_group_add_action ( GtkActionGroup* action_group, GtkAction* action )
Adds an action object to the action group. Note that this function
does not set up the accel path of the action, which can lead to problems
if a user tries to modify the accelerator of a menuitem associated with
the action. Therefore you must either set the accel path yourself with
gtk_action_set_accel_path(), or use
gtk_action_group_add_action_with_accel (..., NULL).
