\begin{ccRefClass}[Qt::]{GraphicsViewCircleInput<K>}

\ccDefinition
An object of type \ccRefName\ 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 \ccc{Del} key removes the last entered point. The \ccc{Esc} 
key removes all entered points.


\ccInclude{CGAL/Qt/GraphicsViewCircleInput.h}

\ccParameters

The template parameter of \ccRefName\ must be a \cgal\ \ccc{Kernel}.

\ccConstructor{GraphicsViewCircleInput<T>(QObject *p, QGraphicsScene* s, int pointsOnCircle = 1);}
{\ccc{p} is a parent object. \ccc{s} is the scene where the circle is generated. \ccc{pointsOnCircle} is the
  number of points on the circle to be generated, that is the default value \ccc{1}
  corresponds to the case center/radius.}

\ccHeading{Signals}

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