Member Typedef Documentation

template<typename Simulator >

typedef unspecified_type CGAL::Kinetic::Qt_widget_2< Simulator >::Listener

The listener base to listen for when to update the picture.

This class includes an extra method Qt_widget widget() which returns the Qt_widget object which can be used for drawing.
