That's actually a good thing for me... I can use RETALL to get back in
action, and then kill it the old fashioned way (File->Close).
Formerly, I was letting the window get killed by the window manager,
asking to save changes if appropriate, and if "Cancel" is hit,
redisplaying the entire widget. This way is much cleaner.

My predecessor used this in all his widgets. Makes sense to me. Don't
know if it does an actual cleanup, but don't really care either.
if (TAG_NAMES(event, /STRUCTURE_NAME) eq 'WIDGET_KILL_REQUEST') then
begin
widget_control, event.top, /destroy
return
endif

Well, the main problem with this method is that during
development, if your program crashes, you can't exactly
close the window easily. :-(
Not that I know this from experience or anything, of course.
Cheers,

Great tip, Benjamin... came in handy, and removes the need for a "Cleanup".
