no need to update config settings everywhere explicitly

2003-10-29  JP Rosevear <jpr@ximian.com>

	* gui/dialogs/cal-prefs-dialog.c (update_config): no need to
	update config settings everywhere explicitly

	* gui/tasks-component.c (update_uris_for_selection): cast the
	widget

	* gui/gnome-cal.h: remove proto

	* gui/gnome-cal.c (setup_widgets): don't update config settings
	explicitly
	(gnome_calendar_update_config_settings): kill

	* gui/e-week-view.c: remove null chars

	* gui/e-tasks.h: remove proto

	* gui/e-tasks.c (set_timezone): set the timezone on the client
	(timezone_changed_cb): changed timezone callback
	(setup_config): setup config stuff
	(e_tasks_init): setup config and widgets here
	(e_tasks_new): construct is dead, no need to track all widgets
	(cal_opened_cb): set the timezone upon opening
	(e_tasks_update_all_config_settings): kill

	* gui/control-factory.c (control_factory_new_control): create the
	calendar ourselves

	* gui/calendar-config.c (on_timezone_set): don't update the
	settings everywhere here, we have config managers now

	* gui/calendar-component.c (impl_createControls): create the
	calendar ourselves

	* gui/calendar-commands.h: remove protos

	* gui/calendar-commands.c: remove dead functions
