Forgive me if this is not the right place to ask this. I have a program with a single window that uses XInput2 for mouse input. I set the event_mask field of the XSetWindowAttributes struct to "ExposureMask | StructureNotifyMask | KeymapStateMask | KeyPressMask | KeyReleaseMask", so I expect to not receive any EnterNotify or LeaveNotify events, yet if I press and hold a mouse button on my window, move the cursor out of the window and then back into the window, I get an EnterNotify event (the only reason the program even listens for these events is for compatibility with operating systems that don't have XInput2). I only get EnterNotify events, not LeaveNotify, and I only get them while holding a mouse button down. Curiously, this behaviour goes away if I call XIGrabDevice in response to a button press.
My question is: why does this happen? This looks like a bug and this issue is trivial to work around (I only even noticed because of an "assert" statement I added), but I want to make sure this isn't caused by me doing something wrong. _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
