I was able to get callbacks on selections working.

I made my tableau subclass off of both vgui_easy2D and vgui_displaybase_selection_callback and
provided implementations of the methods
select(), deselect(), deselect_all().


class my_tableau : public vgui_easy2D, public vgui_displaybase_selection_callback
{
 public:
  // selection callbacks
  bool select(unsigned id) {vgui::out << "my_tableau: " << id << " selected" << vcl_endl; return
true;}
  bool deselect(unsigned id) {vgui::out << "my_tableau: " << id << " deselected" << vcl_endl; return
true;}
  bool deselect_all() {vgui::out << "Deselect all" << vcl_endl; return true;}
}


Then in my constructors, I called

this->set_selection_callback(this);
