I don't know if (*you*) want a Model; it depends on what (*your*) View
does/contains. You said it contains a 'Graph'; I just surmised that a
Graph might be a Model.

As I indicated in my email not using a Model would simplfy my example (but not
by a lot, maybe by 4 1-line methods). The example certainly does not need a Model.


I gave a Model example as it is obvious how to simplify it if you don't want a
Model. Generalising a View only example to include a Model is less obvious.


I remember the 'Yuk' feeling when you first see so many routines. But each
routine is very short, and has a very simple task.

You still seem to be having problems maintaining state:

"Unfortunately I can't get your suggestion to work (yet).
"If I just open the form I don't get the right behavior.
"Things are not initialized properly.
"I still need to find the pointer in the form and then set all of
"its fields correctly.

The standard, and once used to it very simple, technique is to use the three
Methods Externalize, Internalize, & CopyFrom.
