There are xlsclient and xwininfo. Remember that the user may be running two copies of gimp, that ssh tunnelling could be in use and that a remote machine can put windows on an X display, so the question isn't as simple as it may appear. The is an X security protocol (which isn't widely used) which hides some of this information from applications which don't need to know, and remote machines may have a completely different idea of a "process" so in general getting the process id for a window isn't always possible. -- Dr. Andrew C.
