My only problem now is that filling a treeview with 200 elements is s slow if you do it this way. You probably want to disconnect the model from the view while updating, to avoid that every addition regenerates the view. You set the model again at the end of each bunch of updates. You can see some tricks to improve the performance of treeviews at the pygtk.org FAQ.

Hi again, First of all, thanks Felix for the tips! I didn't know about os.walk, which is very helpful. Now eveything is worked as expected (using the gobject.idle_add trick). My only problem now is that filling a treeview with 200 elements is s slow if you do it this way. Anyway, thanks for helping everyone! I hope i can release this app in the near future.

Re: [pygtk] Updating a progressbar inside a recursive function
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.
