Re: Fwd: how do I delete a row in a Gtk::ListViewText

["Francis (Grizzly) Smit" <grizzly smit id au>]

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
