Thanks for the reply. Unfortunately, even when I include a
variable, all of the buttons start out selected. I noticed that this is the
case when I create a StringVar (rather than an IntVar, where the buttons start
out correctly unselected). So, here's another simple example where all of the
radio buttons start out incorrectly selected:
from tkinter import *
root = Tk()
root.grid()
v = StringVar()
Radiobutton(root, text = "Test RadioButton 1", variable=v,
value="1").grid(row = 0, column = 0, sticky = W)
Radiobutton(root, text = "Test RadioButton 2", variable=v,
value="2").grid(row = 1, column = 0, sticky = W)
root.mainloop()
Any ideas on how to have a StringVar() associated with a group of Radiobutton
objects where all of the radio buttons start off unselected?
