How can my Delphi application (A) know which area of "someone else's application (B)" was repainted?
when you put something over a form, and then move it. I think Windows repaints just the area that was covered, not the whole area.
I would like to know the position and size of this area that is being repainted.
Is there any hook that can tell me teh region that needed to be repainted?
eg. My aplication is watching "Firefox" and I MOVE A "NOTEPAD" over it.
as the notepad is moved, firefox is repainted in those areas.
