I'm trying to read the content from a CSV file and create a setup window in which I can set new values in the radiobuttons and save them. For this, I've created a loop which creates N-1 rows from a CSV whose content is:
Row0;T
Row1;M
Row2;-
Row3;C
Row4;O
The problem is than when I try to get a new value by clicking a different radio button, I don't get that value. I've tried using the methods select, invoke, creating a function which prints what's selected, but nothing returns the correct value.
I think the problem is between lines 44 and 88

CodePudding user response：
You have used same instance variable self.element in the for loop of creating those radiobuttons. So after the for loop, self.element will refer to the last item of self.radioInbound.
Actually the instance variable self.element is not necessary. And you need to pass the corresponding index to self.selected() for those radiobuttons using default value of lambda assigned to command option when creating those radiobuttons:
### actually don't need to inherited from ttk.Frame ###
