Are you using Tkinter?
You could bind '' to nothing in the entry widget. eg:
self.answer = Tkinter.Entry(master)
def noop(e):
return 'break'
self.answer.bind('', noop)
--- actually, scratch that. For Tkinter, just make the widget disabled.
self.answer.config(state=Tkinter.DISABLED)
Just remember that it needs to be enabled when you put the answer in.

Are you using Tkinter or another GUI toolkit? In Tkinter you could use a Label widget, which is never editable, or you could use a Text widget with its 'state' option set to 'DISABLED' like this: t=Text(state=DISABLED) Kent ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
