In the code below I get the error below.
I'm trying to create a class for several widgets and make the "interact"
within a main Frame. Can't figure it out (lack of programming
experience) and couldn't find an eye opening example.
I understand that the toolbar has no way to access the txt in the
editor, how do I make it so?
TIA,
Ingo
