added internal EComponentListener object, to listen for the activated Cal.
2002-08-16 Rodrigo Moya <rodrigo@ximian.com> * cal-client/cal-client.[ch]: added internal EComponentListener object, to listen for the activated Cal. (cal_client_class_init): added "backend_died" signal. (cal_client_destroy): clean up component listener. (backend_died_cb): new callback for getting signals from the EComponentListener. (cal_opened_cb): setup component listener. * cal-client/Makefile.am: added libetuil to needed LIBS. * gui/gnome-cal.c (backend_died_cb): new callback. (gnome_calendar_construct): connect to "backend_died" signal on all CalClient's we create. svn path=/trunk/; revision=17787
