new function to see if the event dates have changed (including any
2000-05-01 Damon Chaplin <damon@helixcode.com>
* cal-util/calobj.c (ical_object_compare_dates): new function to see
if the event dates have changed (including any recurrence rules).
It is used for optimization when we get the "object_changed" signal.
We have to do far less work if the dates are unchanged.
* gui/e-week-view.c:
* gui/e-day-view.c: only draw the selection when we have the keyboard
focus, since the user expects to be able to type in a new event when
the selection is shown. Also keep the selection when we lose focus,
but just don't show it.
Also quite a few changes to cope with the new client/server
architecture.
* gui/e-day-view-top-item.c (e_day_view_top_item_draw):
* gui/e-day-view-main-item.c (e_day_view_main_item_draw):
* gui/e-week-view-main-item.c (e_week_view_main_item_draw_day):
only draw the selection if the widget has the keyboard focus.
* gui/gnome-cal.c (mark_gtk_calendar_day): fixed so it works with
events longer than one day. And changed the code for updating events
in the new views.
