2000-08-28  Federico Mena Quintero  <federico@helixcode.com>

	* cal-client/cal-client.c (cal_client_is_loaded): New function.
	We need this from code that dynamically updates from a client and
	could not have connected to the "cal_loaded" signal right after
	the client was created.

	* gui/calendar-model.c (load_objects): Do not try to load the
	objects if the client has not been loaded yet.
	(cal_loaded_cb): Check the status value.

	* gui/calendar-model.h (CalendarModel): Declare the private
	structure here so that gdb will give me love.

	* pcs/cal-factory.h (CalFactory): Likewise.

	* pcs/cal.h (Cal): Likewise.

	* cal-client/cal-listener.h (CalListener): Likewise.

	* cal-client/cal-client.h (CalClient): Likewise.

	* pcs/cal-backend.h (CalBackend): This no longer has a private
	structure, so remove it.

	* cal-util/Makefile.am (libcal_util_la_SOURCES): Removed the
	vCalendar and old iCalendar cruft.
	(libcal_utilinclude_HEADERS): Likewise.
	Removed the obsolete iCalendar test program.
