TreeView : selected_foreach_iter callback

[Xavier Larrodé <xlarrode gmail com>]

Hi, 
I'm adding multiple selection on my TreeView, following the gtkmm tutorial.
So i created a callback , but my program never enter on this function.

May i need to connect other event to my treeview in order to do that ? 

<code>
  _treeview->append_column( *pColumn ); // Passes a Reference (&) to what 
  _treeview->append_column("Name", _model.name);
   //Fill the TreeView's model
  Gtk::TreeModel::Row row = *(_refTreeModel->append());
  row[_model.type] = "SceneNode";
  row[_model.name] = "Root";
  
  _treeview->set_headers_visible(true);
  _treeview->set_rules_hint(false);
  _treeview->set_reorderable(false);
  _treeview->set_enable_search(true);
  _treeview->set_search_column (1);

  Glib::RefPtr<Gtk::TreeSelection> refTreeSelection =
    _treeview->get_selection();
  refTreeSelection->set_mode(Gtk::SELECTION_MULTIPLE); 
 
 refTreeSelection->selected_foreach_iter(
    sigc::mem_fun(*this, &ProcessGroup::selected_callback) );

  _treeview->show();

  _treeview->add_events(Gdk::BUTTON_PRESS_MASK);
  _treeview->add_events(Gdk::KEY_PRESS_MASK);     
...
</code>

Thanks
