[comp.windows.x] Getting Motion Events

wolf@cbnewsh.att.com (thomas.wolf) (06/13/90)

Question regarding MotionNotify events:  Is it possible to tell the server
to generate an event for each pixel the pointer travels through?  My 
server reports every event if the pointer is moved slowly but begins skipping
coordinates when the pointer is moved rapidly.  I tried adjusting the
"acceleration" using XChangeControlPointer() but that didn't seem to help.

Any info would be appreciated,
Tom

Nope.  The protocol does provide a motion buffer history mechanism
(see XGetMotionEvents) to permit gathering of finer-grained motion
than is reported by motion events, but lots of servers don't implement
this mechanism.
