[Pythoncard-users] Using Notebook

[Jussi S. <jus...@pp...>]

I don't know what is the correct way to answer questions in this list, 
so I just send this as a new message.

I just spent a couple hours wondering the same issue. The solution is to 
change the line:

class XYZ(model.Background)

 in your independent PythonCard application that is to become a tabsheet 
to be like this:

class XYZ(model.PageBackground)

Cheers,
