2236.0. "Multiple displays and pointers" by KAOU35::DLEROUX () Thu Feb 08 1990 14:36

    
    I'm writing an workstation conferencing application which requires
    me to have windows on multiple workstations.  
    
    What I would like to know is if it is possible to have a "dummy"
    pointer on all the displays which will follow the lead of the pointer
    on the first workstation.
    
    I know that it is impossible(?) to have multiple pointers on one display
    therefore is there some way to "simulate" a second pointer on a display
    without using up too much of their small cpu resources?
           
    I am looking for any suggestion which you have to offer.

    I have tried something along these lines.  You can easily get the
    cursor on one screen to track another, and get button press events sent
    to the appropriate window.  Performance is probably not acceptable for
    most applications, but I havent gone too deep into it.
    
    However (see note 2244) I havent yet got this to work with the
    DECwindows window manager running, or to send events to applications
    using the toolkit.  "Pure" X applications are OK.  This may just be
    errors in my programming, so I'll keep you posted.
