//! The code for editing is in there, but it seems that the changes are not
//! passed to the TreeModel. So we need to catch the editing events and feed
//! data to the TreeModel. To detect that editing is done we need to connect
//! to Gtk::CellEditable's signal: editing_done. We can obtain pointer to the
//! CellEditable from the CellRendererText's signal editing_started.
//! For details see comments in the implementation of on_button_press_event
