To convert a path to an iterator, use Gtk::TreeModel::get_iter(const 
Gtk::Treemodel::Path&), and then derefence the iterator (a row is just a 
dereferenced iterator).

However, you probably want to convert all the paths to rows with a suitable 
functor using Gtk::TreeSelection::selected_for_each_path().  (As an example 
you can see:

and
