You have stumbled across the wrong list. ;-) This list is about standards for communication between window managers, specialized pager apps, and applications. It isn't for questions on how X work and writing Xlib applications. Since the list is relatively low volume I will include a quick explanation to your two questions, but please take any further questions about how X work elsewhere.

The granularity of motion events is not guaranteed, but a client selecting for motion events is guaranteed to get at least one event when the pointer moves and comes to rest. > 2) I have written an X client which moves the pointer by XWrapPointer() > function, when executing this program and the program of 1), the last one > doesnot detect the pointer motion caused by the XWrapPointer().

MotionNotify events are only generated when the motion begins and ends in the window. If pointer motion causes the pointer to be in a different window than before, EnterNotify and LeaveNotify events are generated instead of a MotionNotify event. _______________________________________________ wm-spec-list mailing list wm-spec-list@gnome.org http://mail.gnome.org/mailman/listinfo/wm-spec-list
