2001-09-18  JP Rosevear  <jpr@ximian.com>

	* gui/dialogs/schedule-page.*: A page that shows the meeting time
	selector and free/busy data for attendees

	* gui/dialogs/meeting-page.c: use the meeting model to track/edit
	attendees, remove table value conversion routines and simple table
	routines
	(set_attendees): take a pointer array
	(meeting_page_destroy): destroy the pointer array, save state
	(meeting_page_init): new pointer array
	(meeting_page_fill_widgets): don't null the deleted attendees
	field
	(popup_delegate_cb): array add
	(popup_delete_cb): array add
	(cleanup_attendees): iterate over the array to unref now
	(meeting_page_fill_widgets): don't null out fields, no need to add
	attendees here
	(invite_entry_changed): use e_meeting_attendee routines
	(popup_delegate_cb): ditto
	(popup_delete_cb): ditto
	(meeting_page_new): take new arg and pass it to construct
	(meeting_page_construct): take new arg, use e-meeting-model
	routines to construct table

	* gui/dialogs/task-editor.c (task_editor_init): new meeting model
	(task_editor_destroy): unref the model

	* gui/dialogs/event-editor.c (event_editor_init): make new model
	and pass it to meeting and schedule pages
	(event_editor_set_cal_client): virtual function, set meeting model
	client
	(event_editor_edit_comp): add the attendees to the model
	(event_editor_destroy): unref model

	* gui/dialogs/comp-editor.h: add virtual function

	* gui/dialogs/comp-editor.c (comp_editor_set_cal_client): make
	set_cal_client a virutal function

	* gui/e-meeting-types.h: generally useful type defines

	* gui/e-meeting-time-sel*.[hc]: Move here and use an e-table for
	the attendee list and extract display information from the new
	meeting model and attendees

	* gui/e-meeting-time-sel.etspec: spec for the table

	* gui/e-meeting-attendee.[hc]: meeting attendees for the model,
	with to/from conversions for CalComponentAttendee structure, emits
	changed signal and allows getting and setting of free busy
	periods

	* gui/e-meeting-model.[hc]: move the model out on its own

	* gui/e-itip-control.c (write_error_html): clean up warnings
