The dispatch code is deep inside an X window system toolkit, compiled separately and made into a library. The function is a member function for either a toolkit object, in which case I would know more, or a user application program object, in which case I know absolutely nothing. I don't know the difference, and it doesn't matter, since even if I did, the application program objects are still totally undefined. The only thing I know is that it is a member function; the only way I know that is I have a non-null object ptr. (The dispatch mechanism allows for calling non member functions as well, but that's easy.). -- Gary Aitken Solbourne Computer Inc.
