add sequence_complete_id to EAddressbookModel and stop_state_changed to

2001-05-23  Chris Toshok  <toshok@ximian.com>

	* gui/widgets/e-addressbook-model.h: add sequence_complete_id to
	EAddressbookModel and stop_state_changed to
	EAddressbookModelClass.  also, add prototype for
	e_addressbook_model_can_stop.

	* gui/widgets/e-addressbook-model.c (remove_book_view): disconnect
	from "sequence_complete", and set search_in_progress to FALSE.
	(sequence_complete): set search_in_progress to FALSE and emit
	"stop_state_changed."
	(e_addressbook_model_class_init): create the "stop_state_changed"
	signal.
	(e_addressbook_model_init): init stuff.
	(book_view_loaded): connect to "sequence_complete" signal.
	(book_view_loaded): set search_in_progress to TRUE and emit
	"stop_state_changed"
	(e_addressbook_model_stop): set search_in_progress to false, emit
	"stop_state_changed", and set our status to "Search Interrupted."
	(e_addressbook_model_can_stop): return search_in_progress.

	* gui/widgets/e-addressbook-view.c (e_addressbook_view_init):
	connect to the stop_state_changed signal on EAddressbookModel.
	(stop_state_changed): new function.
	(e_addressbook_view_can_stop): call e_addressbook_model_can_stop.

	* gui/component/addressbook.c (update_command_state): use
	e_addressbook_view_can_stop to set the sensitivity of the stop
	button.
