2000-05-08  Federico Mena Quintero  <federico@helixcode.com>

	* pcs/cal-backend.h (CalBackendClass): CalBackendClass now is just
	an interface for calendar backends; this is an abstract class.
	Put in the vtable for the backend methods.

	* pcs/cal-backend.c (cal_backend_new): Removed function, since
	CalBackend is not just an abstract class.
	Removed implementation-specific functions and made public
	functions call the virtual methods instead.

	* pcs/cal-backend-imc.[ch]: New files with the CalBackendIMC
	implementation; this implements a backend for iCalendar and
	vCalendar files.  Moved the implementation-specific stuff from
	cal-backend.[ch] to here.

	* pcs/cal-backend-imc.c (CalendarFormat): Moved enumeration to
	here.  Added a CAL_UNKNOWN value for when the backend is not
	loaded yet.
	(cal_backend_imc_init): Initialize priv->format as CAL_UNKNOWN.
	(save_to_vcal): Use the same VCProdIdProp value as in
	cal-util/calobj.c.  Use "1.0" as the VCVersionProp as per the
	vCalendar spec.
	(ensure_uid): Return nothing, since the result value need not be
	used anymore.
	(add_object): Since we mark the calendar as dirty anyways, we do
	not need to check the result value of ensure_uid() anymore.
	(remove_object): Asssert that we know how to handle the object's
	type.  We do this in add_object() anyways.

	* pcs/Makefile.am (libpcs_a_SOURCES): Added cal-backend-imc.[ch].

	* gui/gnome-cal.c: Replaced debugging printf()s with g_message()
	so that we can see the line number where they occur.

	* gui/gnome-cal.c (gnome_calendar_load_cb): Sort of handle the
	LOAD_METHOD_NOT_SUPPORTED result code, and added a default for the
	switch.

	* cal-client/cal-listener.h (CalListenerLoadStatus): Removed
	enumeration; it is stupid to translate all values for the
	CalClient when it is going to translate them again.
	(CalListenerClass::cal_loaded): This signal now passes the
	LoadStatus directly from the CORBA side.

	* cal-client/cal-listener.c (Listener_cal_loaded): Do not
	translate the status value.

	* cal-client/cal-client.h (CalClientLoadStatus): Added the
	CAL_CLIENT_LOAD_METHOD_NOT_SUPPORTED error code.

	* cal-client/cal-client.c (cal_loaded_cb): Translate the CORBA
	version of the LoadStatus result code.

	* pcs/cal-factory.c (CalFactoryPrivate): New methods field for the
	hash table from method strings to the GtkTypes for backend class
	types.
	(cal_factory_init): Create the priv->methods hash table.
	(cal_factory_destroy): Free the priv->methods hash table.
	(cal_factory_register_method): New function to register a backend
	class for a particular URI method.
	(launch_backend_for_uri): New function to launch a backend for a
	particular URI's method.
	(load_backend): Use launch_backend_for_uri().  Move the error
	notification code from load_fn() to here.
	(create_backend): Use launch_backend_for_uri().  Move the error
	notification code form create_fn() to here; it is #ifdefed out
	since currently cal_backend_create() does not have any error
	reporting capabilities.

	* idl/evolution-calendar.idl (Listener::LoadStatus): Added a
	PROTOCOL_NOT_SUPPORTED error code.

	* pcs/cal-factory.c (cal_factory_load cal_factory_create): Removed
	functions, since they were supposed to be internal only.
	(CalFactory_load): Call queue_load_create_job() directly.
	(CalFactory_create): Likewise.
