Atmaram) Distribution: na Organization: University of Houston Lines: 11 My program has the Window ID of a window on a remote display. I wish to check whether or not the ID is valid (that is, whether the window still exists), before doing an XSendEvent. Any pointers as to how I can determine this ? Thanks. Atmaram atmaram@cs.uh.edu
