    # To subscribers of the xforms list from "zaphodb" <zaphodb@casema.net> :


    II would like to prevent users from exiting a program without warning them
    to save their data first.
    I've included a signal handler that catches (catchable) signals, and now I'm
    to find out how I can detect the fact that a user is pressing the window's
    quit or kill button.
    I take it this isn't done via the unix signalling mechanism but is handled
    by my windowmanager?
    I'm running afterstep / kde (2 machines) on Linux using xforms88

    Any help will be appreciated.

    TC: any news on the canvas demo issue ?
    Remember me including the fl_set_idle_delta(0) between fl_initialize and
    and you commenting that this shouldn't have worked?

    Zaphod B.
