	GraphicsViewCircleInput (QObject *p, QGraphicsScene *s, int pointsOnCircle=1)

Signals
void	generate (Object o)
	The object o contains a std::pair<K::Point_2, K::FT> for center and radius, or a std::pair<K::Point_2, K::Point_2> for two points defining the circle, or CGAL::array<K::Point_2, 3> for three points defining the circle.
