Honestly, I have seen the  Gtk::TreeModel::Path::get_indices() method
before, but I didn't consider it because I didn't know why the array
of int(s), while I need just one int... Jose came again to give me
light... because TreeStore nodes also exist...

So,

Glib::RefPtr <Gtk::ListStore>  m_refTreeModel;
Gtk::TreeModel::iterator iter;
Gtk::TreeModel::Path cellpath=m_refTreeModel->get_path(iter);
std::vector<gint> rowindex = cellpath.get_indices();

The right value is rowindex[0]... ;)

Thanks to all,

Glus.
