in the example:
in void MyWidget::on_realize()
change
   attributes.event_mask = get_events () | Gdk::EXPOSURE_MASK;

to
   attributes.event_mask = get_events () | Gdk::EXPOSURE_MASK | 
Gdk::BUTTON_PRESS_MASK;

and add

bool MyWidget::on_button_press_event (GdkEventButton* event)
{    std::cout << "button pressed" << std::endl;
}
