Now takes object and flags parameters. Likewise. Likewise.

1998-04-13  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* gncal-week-view.c (gncal_week_view_update): Now takes object and
	flags parameters.
	* gncal-day-view.c (gncal_day_view_update): Likewise.
	* gncal-full-day.c (gncal_full_day_update): Likewise.
	(child_focus_in): New function.  In conjunction with
	child_focus_out(), these only display the handles in the child
	when it is focused.  The result is that the user can see more of
	the child's text when nothing is focused, and we can also display
	fatter and nicer drag handles.

	* gnome-cal.c (gnome_calendar_object_changed): Now takes an
	additional flags parameter
	(gnome_calendar_update_all): Made function static.  Now takes
	changed object and flags parameters as well.
	(gnome_calendar_object_changed): Now takes additional flags
	parameter to indicate what changed in the specified object.

	* calobj.h (CalObjectChange): New enum with flags to describe what
	has been changed in an object.
