With substantial help I was able to get some more stuff to work as
expected. Now I am struggling with the fact that the menubar does
indeed have the menus I installed but the few widgets I placed into
the window simply don't appear...
Hmm - well, yes, why?? (As always, there's a FRGO placed here and there)
Nothing inherits from any TK widget. I added ctk::button to application-object and made other changes I noted in what I sent and could see a panel. Actually I went back and exported button from Celtk, which was just an oversight.
How do I debug what is being sent to wish ?
Hack ctk::tk-format-now in various ways to see all or selected messages.
Totally late, gotta run, but will resend shortly.

Thx for any inputs.
