Re: scroll-bar-toolkit-scroll

    As I read the man page, XmCR_DRAG is received while the user is
    dragging the slider for "each incremental change of position", so it
    would be neither up nor down event.

Stefan, is that correct?  It sounds like the event produced by
XmCR_DRAG ought to scroll the buffer based on the new position and
redisplay--is that right?

    I've used x_send_scroll_bar_event to "translate" the invocation of the
    scroll bar callback to an X event that is handled in XTread_socket
    like other events.  This seemed to be the easiest way to orderly
    produce a scroll bar input event in the kdb queue because I saw no way
    to predict when the callback is called (asynchronously).

Why not just insert the desired event into the Emacs event queue?
That can be done at any time, asynchronously.
