Fixes #41676

2003-07-14  Rodrigo Moya <rodrigo@ximian.com>

	Fixes #41676

	* gui/dialogs/alarm-options.c (palarm_options_changed_cb,
	  repeat_spin_button_changed_cb, repeat_unit_changed_cb): new callbacks for
	managing modifications in the 'Run a program' alarm case.
	(repeat_toggle_toggled_cb): if the alarm being edited has a procedure
	action, call palarm_options_changed_cb.
	(init_widgets): connect new callbacks.
	(alarm_to_dialog): disable 'OK' button if a procedure alarm.
