Added the array of objects and the hash table of UID->array index.
2000-06-13 Federico Mena Quintero <federico@helixcode.com> * gui/calendar-model.c (CalendarModelPrivate): Added the array of objects and the hash table of UID->array index. (calendar_model_row_count): Return the length directly from the array instead of asking the Wombat. (calendar_model_value_at): Implemented. (calendar_model_new): Create an empty model. We provide a new setter function now. (calendar_model_construct): Removed function. (calendar_model_set_cal_client): New function to set the calendar client and object type at any time. This lets us reuse a calendar model object. * cal-util/calobj.h (iCalObjectField): Just report whether the object has alarms; not every single alarm. svn path=/trunk/; revision=3547
