Hi all, A probably simple question from a Quixote newbie: In part one of the "Introducing Quixote" documents, just before the "Running the Example Application" heading are a _q_index() and a _q_lookup() function meant to be at a "top" level outside the example class for handling categories and links. They both use: c = CategoryUI(root) So where is this "root" variable coming from? Cheers, Stu -- :: Stuart Hungerford (stuart.hungerford@anu.edu.au) :: ANU Internet Futures Group
