New function to restart a query for the day view. (query_obj_updated_cb):
2001-04-12 Federico Mena Quintero <federico@ximian.com> * gui/e-day-view.c (update_query): New function to restart a query for the day view. (query_obj_updated_cb): Renamed from obj_updated_cb(); updated for queries instead of calendar clients. (query_obj_removed_cb): Likewise. (cal_opened_cb): Just update_query() instead of queueing reloading all the events. (e_day_view_set_cal_client): Likewise. (e_day_view_set_query): Likewise. (e_day_view_set_selected_time_range): Likewise. (e_day_view_set_days_shown): Likewise. (e_day_view_recalc_work_week): Likewise. (e_day_view_queue_reload_events): Removed function now that events are updated entirely by the query. (e_day_view_reload_events_idle_cb): Likewise. (e_day_view_reload_events): Likewise. (e_day_view_init): Use a pretty arrow instead of GDK_TOP_LEFT_ARROW. * gui/e-week-view.c: Analogous changes to the ones in e-day-view.c. (e_week_view_init): Use a pretty arrow instead of GDK_TOP_LEFT_ARROW. * cal-util/timeutil.c (isodate_from_time_t): Return a g_strdup()ed version of the string instead of a pointer to a static buffer. (time_from_isodate): Resurrected function. Polished up to our current standards of paranoia. * pcs/query.c (func_time_now): New function (time-now). (func_make_time): New function (make-time ISODATE). (func_time_add_day): New function (time-add-day TIME N). (func_time_day_begin): New function (time-day-begin TIME). (func_time_day_end): New function (time-day-end TIME). (func_occur_in_time_range): Use time_t values instead of ints. (match_component): Free the stringized component. Free the ESexp result value. * gui/e-day-view.h: Removed a couple of unused prototypes. * pcs/query.c (query_destroy): Oops, disconnect from the backend. * pcs/cal.c (Cal_get_query): Duplicate the query reference before we return it. * gui/calendar-commands.c (pixmaps): Fixed paths to image files. svn path=/trunk/; revision=9266
