[cells-devel] Celtk/cells: No Widgets! Help!

Hi again ...

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)

How do I debug what is being sent to wish ?

Thx for any inputs.

Frank
