It is not possible to create a recursive function over a pyGTK treeStore

[sebastien.abeille at gmail.com]

A little update : I finally found an example of a file browser using
gtkTreestore that parse the file system recursively :
http://www.koders.com/python/fidDB37D29C69F526E5EEA9A7D8B4FC5B87E92A78CC.aspx?s=filter_out_extensions#L113

I still need to check how it works, but I am sure that it will answer
my question.
Thank you
