I found another page that mentions connect_notify(), this time a tutorial :

http://www.gtkmm.org/gtkmm2/docs/tutorial/html/ch08s07.html

The interesting snippet is :
...
class TreeView_WithPopup : public Gtk::TreeView
{
public:
   TreeView_WithPopup();
   virtual ~TreeView_WithPopup();

protected:
   // Override Signal handler:
   // Alternatively, use signal_button_press_event().connect_notify()
   virtual bool on_button_press_event(GdkEventButton *ev);
...
