Yes, but I was thinking of using the returned invalidated region in a clever "backwards" way: If the returned invalidated region equals what it would be if the whole source rectangle was visible, no GraphicsExpose equivalent needed. But if it less (or empty even), doesn't this mean that part or all of the source was obscured, and for the corresponding part of the destination rectangle needs to be generated a GraphicsExpose equivalent event? > Is there a mainloop event that tells you a window is being obscured? > It could be recorded and used later. Too much hassle, and potential race problems anyway? --tml To Post a message, send it to: [email protected] To Unsubscribe, send a blank message to: [email protected] Your use of Yahoo!
