Fixes #56316

2004-04-05  Rodrigo Moya <rodrigo@ximian.com>

	Fixes #56316

	* gui/dialogs/comp-editor-page.[ch]: added "fill_timezones" virtual
	method to CompEditorPage class.
	(comp_editor_page_fill_timezones): new function.
	(comp_editor_page_class_init): initialize new virtual method.

	* gui/dialogs/event-page.c (event_page_fill_timezones,
	event_page_class_init):
	* gui/dialogs/task-page.c (task_page_fill_timezones,
	task_page_class_init):
	* gui/dialogs/task-details-page.c (task_details_page_fill_timezones,
	task_details_page_class_init): implemented new virtual method for pages
	dealing with timezones.

	* gui/dialogs/comp-editor.c (save_comp): call the "fill_timezones"
	method on all pages, and call...
	(send_timezone): ...this function for each hash table item.
