I can't seem to get this function to work. If the item does not exist I
get an exception, rather than a return value of false. Here's an
example:


#!/usr/bin/python

from Tix import *

root = Tk()
listBox = HList(root)
item = "some item"
if not listBox.item_exists(item, 0):
        listBox.add(item, itemtype=TEXT, text=item)


Any ideas?

Peter
