Fixes #53137

2004-03-04  Rodrigo Moya <rodrigo@ximian.com>

	Fixes #53137

	* gui/dialogs/comp-editor-page.[ch]: made fill_widgets virtual
	method return a gboolean.
	(comp_editor_page_fill_widgets): return value from virtual method
	implementation.

	* gui/dialogs/event-page.c (event_page_fill_widgets):
	* gui/dialogs/meeting-page.c (meeting_page_fill_widgets):
	* gui/dialogs/recurrence-page.c (recurrence_page_fill_widgets):
	* gui/dialogs/schedule-page.c (schedule_page_fill_widgets):
	* gui/dialogs/task-details-page.c (task_details_page_fill_widgets):
	* gui/dialogs/task-page.c (task_page_fill_widgets):
	* gui/dialogs/alarm-page.c (alarm_page_fill_widgets): return value,
	as expected from the virtual method signature.

	* gui/dialogs/comp-editor.c (comp_editor_append_page): dont add the
	page if there was an error calling the fill_widgets method.
