The Wombat now keeps track of which categories are present in the objects
2001-07-31 Federico Mena Quintero <federico@ximian.com> The Wombat now keeps track of which categories are present in the objects of a calendar. It will notify the clients of changes in this set. This is to make the category drop-down menus in the calendar/tasks views be always up to date. * idl/evolution-calendar.idl (Listener): Added a notifyCategoriesChanged() method. The Wombat now keeps track of the categories within a calendar. * cal-client/cal-listener.[ch]: Switched it to use BonoboXObject. Also added the notifyCategoriesChanged implementation. * cal-client/cal-client.[ch]: Added a "categories_changed" signal. * pcs/cal-backend-file.c: Maintain a list of the live categories. (update_categories_from_comp): New function to maintain the set of live categories. (add_component): Update the set of categories. (remove_component): Likewise. (open_cal): Notify about changes in the set of categories. (create_cal): Likewise. (cal_backend_file_update_objects): Likewise. (cal_backend_file_remove_object): Likewise. (notify_categories_changed): New function to notify the clients about the current set of categories. * pcs/cal.c (cal_notify_categories_changed): New function. svn path=/trunk/; revision=11536
