Dear All         You will no doubt remember my  appeal  for  help
with  regard  to creating good user interfaces to applications in
Smalltalk (That was back in October).  Well a number of you  good
people  did  reply  and advised us to read up on MVC, and explore
the system's MVC classes.

Such replies included one by Ken Auer, who very kindly offered to
come over to England, with his lovely wife, and tell us all about
MVC if we could pay his expenses . (har har) :-) .

At present, with the help of Trevor Hopkins at Manchester,  we've
learned  how  to produce simple MVC type interfaces, but are con-
stantly frustrated by how difficult it is to produce very complex
interfaces  (which  include state, or modes), or interfaces which
are generic or should I say reusable .

Obviously apple have decided to move away from the MVC idea,  for
reasons  known only to themselves, and I don't think they will be
alone in  trying  to  find  some  other  interface  paradigm  for
Smalltalk cos MVC is no panacea .

But there should be scope for upward compatibility to some extent
surely  ?  For example our latest version of Smalltalk [ParcPlace
VI2.2 VM1.1] includes a multiple inheritance facility, which none
of the standard system classes use, but it keeps working.

Any comments gratefully received

Neil
