Inherits from

CGAL::Qt::GraphicsViewInput.

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.

Template Parameters
Kmust 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.
