# just to be cute, let's disable the undo option:
Edit_button.menu.add('command', label="Undo")
- # undo is the 0th entry...
- Edit_button.menu.entryconfig(0, state=DISABLED)
+ # Since the tear-off bar is the 0th entry,
+ # undo is the 1st entry...
+ Edit_button.menu.entryconfig(1, state=DISABLED)
# and these are just for show. No "command" callbacks attached.
