Re: [Pythoncard-users] getParent() AttributeError

I'll try to answer your question, though you never bothered to comment 
on my suggested "solution"  to your earlier request concerning 
multilingual GUIs.

I doubt walkthrough3 has got nothing to do with tabsheets, though the 
term childwindow appears in tabsheet terminology also.

I had the same problem also. After a considerable number of hours 
wandering in total darkness I found the way that seems to work for me at 
least. In the initalizers for the individual tabsheets I do:
       # fr becomes the pointer to the wxframe window
       self.fr = self.GetParent().GetParent().GetParent()

Then in my code I can say
       self.fr.showMsg(0, 'Maximum points per item can only be given for 
test type 2')
when I want to use the message function showMsg defined in the "main" 
class which only has to know how to use the message field outside of the 
tab sheet area. Or:
       self.fr.maxPnts = 100
to set the value of the attribute maxPnts in the "main" class or:
       self.fr.test.readFromDisk(path)
to refer to an instance of a separate Test class to use its readFromDisk 
method.
