2004-03-05 Rodrigo Moya <rodrigo@ximian.com> * gui/alarm-notify/alarm-notify.c (alarm_notify_init): set a GConf listener callback to list for changes in selected calendars. (alarm_notify_finalize): remove the GConf notification listener. (conf_changed_cb): callback to react on configuration changes. Process the new selected calendars and remove the unselected ones. (process_removal_in_hash): callback to remove unselected calendars. svn path=/trunk/; revision=24973
