[Tutor] Tkinter ... deactivating a Text window when a radiobutton is chosen

[Patrick Lorenz]

I'd appreciate some help.  I am just learning Tkinter, and want to 
deactivate a Text window when a certain radiobutton is selected.  I 
cannot figure it out.  I believe I need to reset the state option of the 
Text window to be 'disabled', but I'm not able to find  a way to do it, 
even though I have tried different ways, including using the radiobutton 
command option, etc.
