OK got it my code now is:
Gtk::ListViewText::SelectionList sellst =
m_listviewtextAvailable->get_selected();
if(sellst.empty()) return;
Glib::RefPtr<Gtk::TreeSelection> ts =
m_listviewtextAvailable->get_selection();
Gtk::TreeModel::iterator sel_it = ts->get_selected();
int sel = sellst[0];
Glib::ustring selrow = m_listviewtextAvailable->get_text(sel);
m_listviewtextOrderBy->append(selrow);
//erase(sel_it);
Glib::RefPtr<Gtk::TreeModel> reftm =
m_listviewtextAvailable->get_model();
Glib::RefPtr<Gtk::TreeStore> refStore =
Glib::RefPtr<Gtk::TreeStore>::cast_dynamic(reftm);
if(refStore){
std::cout << __FILE__ << '[' << __LINE__ << "] it's a
Gtk::TreeStore" << std::endl;
refStore->erase(sel_it);
return;
}
Glib::RefPtr<Gtk::ListStore> refLStore =
Glib::RefPtr<Gtk::ListStore>::cast_dynamic(reftm);
if(refLStore){
std::cout << __FILE__ << '[' << __LINE__ << "] it's a
Gtk::ListStore" << std::endl;
refLStore->erase(sel_it);
}
That works and my model turns out to be a Gtk::ListStore I found some
code here
