Refreshing windows

["C. Ann Dent" <Ann@drea-phoenix.arpa>]

	I would like to advise a dynamic window in my program in GENERA
7.0 to perform some side-effect whenever that window is refreshed,
scrolled or updated and redisplayed in any way. I need a handle on what
methods, generic functions, or otherwise get called whenever a window is
refreshed, scrolled or updated and redisplayed.  I would substitute the
handler for the "HANDLER2REFRESH" in the following code fragment:

	(scl:advise HANDLER2REFRESH :after my-side-effect-after-refresh nil
	  (format *debug-io*
	          "~& Tracing my advice/side-effect after refreshing
window"))

			Ann
