[pygtk] Updating a progressbar inside a recursive function

[Felix Rabe (public)]

Hi Adolfo,

You might not need to use recursive code, and generators aren't too bad.  Have you looked at os.walk() already?

I have PyGTK example code that uses it.  I have to package it up though, but I'll do that on (your) request.  Feel free to answer in Spanish if that's your mother tongue.

Greetings,
Felix
