I am stuck here. I don't have a m_tree_store...!

Tried this way:

  // two columns: ElementType (editable) and ID (not editable)
  int editableColumn = m_treeView.append_column_editable("Element Typ",
m_columns.m_elementType);
  m_treeView.append_column("Element ID",  m_columns.m_elementId);

  Gtk::CellRenderer *renderer =
m_treeView.get_column_cell_renderer(editableColumn);
  Gtk::CellRendererText *text_renderer =
dynamic_cast<Gtk::CellRendererText *>(renderer);
  if (text_renderer) {
	text_renderer->property_editable() = true;
	text_renderer->signal_edited().connect(slot(*this,
&ElementsTable::rowChangedCallback));
  }
