Show directories and files using GtkTreeView

Having the following base code for walking a开发者_StackOverflow中文版 directory I would like to fill a GtkTreeView with the directory and files information to the user:

import os
for (path, dirs, files) in os.walk("/etc"):
    print path, dirs, files

C code is also welcome since it is easy to translate to pygtk.

Look at this question.

The question was funnily the other way around: how to get the directory structure which can then be filled into the TreeView.
