CGAL::Kinetic::Qt_widget_2<Simulator>

Definition

The class Kinetic::Qt_widget_2<Simulator> implements a graphical interface for 2D kinetic data structures.

#include <CGAL/Kinetic/IO/Qt_widget_2.h>

Types

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.

Creation

Kinetic::Qt_widget_2<Simulator> a ( int argc, char *argv[], Simulator::Handle);
default constructor.
