If you're using multiple selection, you *must* use 
selected_foreach_iter().  The way I've used this, is just have a 
function that adds each selected iter its passed to a vector, then play 
with the iterators that are in the vector. Not very hard at all.

If you've got a single selection model, you can simplify this call.
For example:

Gtk::TreeModel::iterator iter = _exp_selection->get_selected() ;
Gtk::TreeModel::Row row = (*iter) ;

But remember, if you do have multiple selection enabled, get_selected() 
will *not* work.

Good luck,
