Definition

An object of type GraphicsViewCircleInput creates a circle, defined by either center and radius, or two or three points on the circle.

A new vertex is inserted every time the left mouse button is released. The Del key removes the last entered point. The Esc key removes all entered points.

K	must be a model of Kernel.

Creation
	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.
