Hi,

This sort of question is beginning to look repetitious, sorry. Is there a 
FAQ for this newsgroup? How do I get it?
That wasn't the question. I am using Think Pascal / TCL. I want the main 
window to be a modeless dialog (or window with text fields), and two 
subsidiary windows (not usually visible) to handle text and graphics.
The program reads in x-y coords of spider webs, and calculates a few
hundred parameters, then outputs the results to FileForce files. The
program has to display some changeable information (like date) on screen,
and optionally display a picture of the web, and a text log file.
Now, how is this best structured. CDocument is not a subclass of CDLOG-
Director. Should I make itsWindow the log window, have a separate director
to deal with the graphic window, and a subclass of CDLOGDirector to handle
the dialog? Seems awkward, because the dialog has a couple of buttons to
skip the web, or get the next from the file. I have to keep passing data
back and fore to save to the file. 
Sorry this is so rambling. If people email, I'll summarise to the net.
Thanks in advance.

As some kind net-soul explained to me:

Your DLOG window should be supervised by an instance of DLOGDirector, and
then the DLOGDirector should be supervised by an instance of CDocument. 
Because CDocument is a subclass of CDirectorOwner, it can supervise another
Director.

I hope this is right! I have not yet tried it myself...
