Added get_uids() method to get a list of UIDs based on object types.
2000-02-08 Federico Mena Quintero <federico@helixcode.com> * evolution-calendar.idl (Cal): Added get_uids() method to get a list of UIDs based on object types. * cal-backend.c (cal_backend_get_uids): Implemented get_uids() in the backend. * cal.c (Cal_get_uids): Implemented get_uids() method. * cal-client.c (cal_client_get_uids): Implemented client-side function. * cal-util.c (cal_obj_instance_list_free): Doh. Free the list, not the last link. (cal_obj_uid_list_free): New function to free a list of UIDs. * GnomeCal.idl (Repository): Removed unused method get_object_by_id_list(). This is just for cleanup purposes and to remind me exactly of what needs to be moved over to evolution-calendar.idl. (Repository): Removed unused get_objects() method. * corba-cal.c (init_calendar_repo_class): Removed the unused get_objects method. * calobj.h (CalObjFindStatus): New status value enumeration for the find function. * calobj.c (ical_object_find_in_string): New function to parse a complete calendar and find a calendar object in it. This should be used instead ical_object_new_from_string() in the future. * evolution-calendar.idl (CalObjInstance): Added an uid field. Now the idea is that whenever calendar object strings are passed around, their UIDs are passed along with them so that the actual object can be pulled from the whole VCAL object using its UID to identify it. * cal-util.h (CalObjInstance): Added uid field. * cal-util.c (cal_obj_instance_list_free): Free the UIDs. * cal-backend.c (build_event_list): Store the object's UID in the instance structure. * cal.c (Cal_get_events_in_range): Copy the UID field to the CORBA structure. * cal-client.c (cal_client_get_events_in_range): Copy the UID field from the CORBA structure. * main.c (gnome_cal_file_menu): Removed unfinished html-month stuff. * Makefile.am (gnomecal_SOURCES): Removed html-month.c. * gnome-cal.c: #include "alarm.h" (mail_notify): Made static. * alarm.h: #include "calobj.h" * corba-cal-factory.h (init_corba_server): Fixed prototype. * quick-view.c (create_items_for_event): Made static. * gncal-todo.c (column_resized): Made static. * layout.c (find_index): Made static. svn path=/trunk/; revision=1699
