2004-05-18  JP Rosevear  <jpr@novell.com>

	* gui/alarm-notify/notify-main.c (init_alarm_service): just set
up
	the alarm notify object

	* gui/alarm-notify/alarm-notify.h: update proto

	* gui/alarm-notify/alarm-notify.c (process_removal_in_hash):
	process removals using the source list
	(list_changed_cb): when the list changes, update
	(load_calendars): initially load the calendars
	(alarm_notify_init): load the calendars here and don't listen
for
	a selection notification
	(alarm_notify_add_calendar): get the source type when adding a
	calendar

	* gui/alarm-notify/notify-main.c (main): no need to
init/shutdown
	gnome vfs

	* gui/alarm-notify/config-data.h: new proto

	* gui/alarm-notify/config-data.c
	(config_data_get_notify_with_tray): routine to get schema value

	* gui/alarm-notify/alarm.c (alarm_ready_cb): no timeout checking
	here, setup_timeout does that
	(queue_alarm): ditto
	(setup_timeout): calculate the timeout better

	* gui/alarm-notify/alarm-queue.c (query_objects_changed_cb):
tidy
	(edit_component): clean up exception handling
	(display_notification): don't show the tray icon if we aren't
	notifying with the tray

	* gui/apps_evolution_calendar.schemas.in.in: add
notify_with_tray
	option
