Fix bug #13723.

2001-10-31  Federico Mena Quintero  <federico@ximian.com>

	Fix bug #13723.

	* gui/gnome-cal.h (GnomeCalendarClass): New signals
	"calendar_focus_change", "taskpad_focus_change", and
	"taskpad_selection_changed".  Renamed "selection_changed" to
	"calendar_selection_changed".

	* gui/gnome-cal.c (gnome_calendar_get_num_tasks_selected): New
	function.
	(setup_widgets): Connect to the focus event signals of the task
	pad and the calendar view widgets.
	(gnome_calendar_delete_selection): Renamed from
	gnome_calendar_delete_event().
	(gnome_calendar_cut_clipboard): Handle the current focus location.
	(gnome_calendar_copy_clipboard): Likewise.
	(gnome_calendar_paste_clipboard): Likewise.
	(gnome_calendar_delete_selection): Likewise.
	(table_selection_change_cb): New callback.

	* gui/calendar-commands.c (sensitize_calendar_commands): Take in
	whether we should unconditionally disable everything.
	(sensitize_taskpad_commands): Analogous function to the above.
	(gcal_calendar_focus_change_cb): New callback, used for calendar
	views.
	(gcal_taskpad_focus_change_cb): New callback, used for the
	taskpad.

	* gui/e-day-view.c (e_day_view_key_press): Use a better test for
	keys that should start editing.  Fixes bug #6447.

	* gui/e-week-view.c (e_week_view_key_press): Likewise.
