treemodelcustom and set_value_impl

[eric jrdn <eric_jrdn2 yahoo fr>]

Hi,
I wish to modify the treemodelcustom example from gtkmm, and let the columns be editable.

First, i did :
  m_TreeView.append_column_editable( "one", m_refTreeModel->get_model_column(0) );
  m_TreeView.append_column_editable( "two", m_refTreeModel->get_model_column(1) );
  m_TreeView.append_column_editable( "three", m_refTreeModel->get_model_column(2) );

instead of m_reTreeView.append(...) in examplewindow.cc

next, a set_value_impl must be implemented. I did this :


void ExampleTreeModel::set_value_impl(const iterator& iter, int column, const Glib::ValueBase& value)
{
  if(iter_is_valid(iter))
  {
      typeListOfRows::const_iterator dataRowIter = get_data_row_iter_from_tree_row_iter(iter);
      const Glib::Value<std::string>* tmp = static_cast<const
 Glib::Value<std::string>*>(&value);
      std::string  value_specific;
      value_specific=tmp->get();
      int row_index = (int)iter.gobj()->user_data;
      Gtk::TreePath tp;
      tp.push_front(row_index);
      typeRow dataRow = *dataRowIter;
      dataRow[column]=value_specific;
      row_changed(tp,iter);

  }
}
I know that the data are modified, but the Treeview does not update. Does anyone knows what i'm missing? On another test case, row_deleted and row_inserted do their job fine...

Thanks
