[gtkmm] multiple lines deletion in a ListStore

[cedric <cedric probesys com>]

Hello,
I m still trying to have my multiple lines deletion work, but without 
any success! :'(
i ve tried to do it alone (without asking you more and more for the 
answers to my problems), but i feel really "blocked" (don t know if this 
word exists!)

i ve spend time to try to understand how the "get_selected_rows" method 
works, but maybe it s not sufficient :-/
could you tell me what is wrong in my code? i ve tried several ways but 
everytime the same seg fault! :p

thanks one more time,
cedric

in the .hh:

...

   Gtk::TreeView billArray;

   Glib::RefPtr<Gtk::ListStore> m_refListStore;
   Glib::RefPtr<Gtk::TreeSelection> refTreeSelection;
   Glib::RefPtr<Gtk::TreeModel> m_refListModel;
   Gtk::TreeModel *m_refListModel;        //same error


-----------------------------------------------------------------------------------------------------
in the .cc:

...

//called when we press the button "delete line(s)"
void BillFormat::on_delline_press()
{    refTreeSelection = billArray.get_selection();
   std::vector<Gtk::TreePath> listHandlePath = 
refTreeSelection->get_selected_rows();

std::cout << listHandlePath.size()<< std::endl;            //diplays the 
correct value
std::cout << (listHandlePath.at(0)).to_string () << std::endl;   
//diplays the correct value

Gtk::TreePath tp = listHandlePath.at(0);            //maybe this is not 
correct ?!?
std::cout << tp.to_string() << std::endl;            //diplays the 
correct value

Gtk::TreeIter iter;
iter = m_refListModel->get_iter(tp) ;        // THIS LINE PROVOQUES A 
SEG FAULT
//m_refListModel is a *TreeModel, tp is a TreePath, but 
"m_refListModel->et_iter(tp);" fails.


/*    const Glib::ustring azer("1");
   iter = m_refListModel->get_iter(azer) ;*/

row = *(m_refListStore->erase(iter));
}
