Fixes #22444

2003-04-21  Rodrigo Moya <rodrigo@ximian.com>

	Fixes #22444

	* gui/calendar-commands.c: added new verbs for occurrence-related
	menu items.
	(delete_occurrence_cmd): added callback for "Delete this occurrence"
	menu item. "Delete all occurrences" is just the same as "Delete".
	(sensitize_calendar_commands): sensitive ocurrence-related menu items.

	* gui/gnome-cal.[ch] (gnome_calendar_delete_selected_occurrence): new
	function.
	(gnome_calendar_get_current_view_widget): made this public.

	* gui/e-week-view.[ch] (e_week_view_get_selected_event):
	(e_week_view_delete_occurrence): new functions.
	(e_week_view_delete_occurrence_internal): real implementation of the
	'Delete Occurrence' logic.
	(e_week_view_on_delete_occurrence): call delete_instance_internal.

	* gui/e-day-view.[ch] (e_day_view_get_selected_event):
	(e_day_view_delete_occurrence): new functions.
	(e_week_view_delete_occurrence_internal): real implementation of the
	'Delete Occurrence' logic.
	(e_week_view_on_delete_occurrence): call delete_occurrence_internal.
