you haven't set focus - thats misleading terminology. When a button
press event occurs on a widget, X itself starts a pointer grab for the
widget so that the button release event will always be delivered to
the same widget. this means that all motion events will be delivered
to the same widget while the button remains depressed.

this is quite different from focus, and uses an entirely different
mechanism.
