[pygtk] Retrieve Iter before "iter selected" in a treeview

[Pasquale Ambrosini]

Hi at all, i have a trouble with treeview and iter in pygtk.
In a list, for retrieve the iter after iter selected, there is a function in
TreeModel:
http://www.pygtk.org/docs/pygtk/class-gtktreemodel.html#method-gtktreemodel--iter-next
and one for first iter:
http://www.pygtk.org/docs/pygtk/class-gtktreemodel.html#method-gtktreemodel--get-iter-first
but how to retrieve iter after iter selected?
It's a stupid question, but i can't find a solution.
Thanks.
