2001-01-03  Federico Mena Quintero  <federico@helixcode.com>

	* gui/calendar-commands.c (new_calendar): Handle the case where
	the calendar view cannot be created; present a warning dialog box.
	(new_calendar): Do not show the widget here, since we already show
	it in control-factory.c.

	* gui/control-factory.c (control_factory_new_control): Handle the
	case where the calendar view cannot be created.

	* gui/component-factory.c (create_view): Ditto.

	* gui/calendar-summary.h: Added prototype for
	calendar_summary_factory_init().
