#include <CGAL/Qt/GraphicsViewCircleInput.h>
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. | |
| CGAL::Qt::GraphicsViewCircleInput< K >::GraphicsViewCircleInput | ( | QObject * | p, |
| QGraphicsScene * | s, | ||
| int | pointsOnCircle = 1 |
||
| ) |
| p | is a parent object. |
| s | is the scene where the circle is generated. |
| pointsOnCircle | is the number of points on the circle to be generated, that is the default value 1 corresponds to the case center/radius. |
