I'm quite new to Python and have a problem which I can't solve.

I want to write a Class which displays a configuration file (dict) in a tkinter frame. It should choose a tk.widged by type of value and for bool values create checkboxes, and for int and strings it should create entries.

After all it should give back a dict with the same keys, but the values changed to tk.*Var() However, with the checkboxes there is no problem. But the int and strings from the entries will not be written through the save_config() function. It seems the tk.IntVar() and the tk.StringVar() don't update when typing something in the entries.

Hope my question is clear. Can anybody please help?

code updated like asked by Bryan Oakley:

It also contains the changes suggested by Martin Finke which brings the solution for me!!

Thanks to enyone!

I suggest a simple change in the __ init __ function of the ConfigurationFrame class:

line self.configuration[name] = entry_int_txt replace self.configuration[name] = self.entry_int

line self.configuration[name] = entry_text replace self.configuration[name] = self.entry_str
