If this filesel is targeting GTK+ 2.0, you should use the new list/tree
widget (GtkTreeView et al.)  This way you can store the directory
information in your own data structure, and export it to the widget as
necessary.

Currently, I am in the midst of making a large change to the model
interface, and it's a little under-documented.  I can check in the
documentation I have later today, with the completed change (assuming I
fully finish.)  Also, please feel free to point out any problems with
the list.  It is under-tested at the moment, and I'm not sure how useful
the API is yet.

Thanks,
