> Can someone please mail or post the reason only one client is allowed > to receive a window's button events while more than one can receive > key and expose events? Curious. That had me baffled for a while too. However, if you read the doc carefully, you'll find that pressing a button starts a passive grab. The limitation to one client sidesteps the question of in which client's name this grab is started. (The reason behind this passive grab is not clear to me. I see no particular benefit to it, and it does cause this peculiar restriction on ButtonPress event selection.) der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu
