## Definition

template<typename K>
class CGAL::Qt::Converter< K >

An object of type `Converter` converts 2D CGAL `Kernel` objects to their equivalent objects in Qt, and the other way round.

Note that some objects have no equivalent. For example the `CGAL::Circle_2<K>` cannot be converted to something in Qt, and the unbounded objects `CGAL::Ray_2<K>` and `CGAL::Line_2<K>` are clipped. Note also that CGAL and Qt sometimes also use the same word for different things. For example line denotes an unbounded line in CGAL, whereas it denotes a bounded segment in Qt.

Template Parameters

  K | must be a model of `Kernel`.

## Creation
| Converter (QRectF clippingRect)
| The clipping rect is used for unbounded CGAL objects.

## From CGAL to Qt
QRectF | operator() (Bbox_2)
| Converts a bounding box.
QPointF | operator() (K::Point_2)
| Converts a point.
QPointF | operator() (K::Circular_arc_point_2)
| Converts a circular arc point.
QLineF | operator() (K::Segment_2)
| Converts a segment.
QLineF | operator() (K::Ray_2)
| Clips the ray and converts the resulting segment.
QLineF | operator() (K::Line_2)
| Clips the line and converts the resulting segment.
QPolygonF | operator() (K::Triangle_2)
| Converts a triangle.
QRectF | operator() (K::Iso_rectangle_2)
| Converts an iso rectangle.
QPolygonF | operator() (std::list< K::Point_2 >)
| Converts a list of points to a polygon.

## From Qt to CGAL
K::Point_2 | operator() (QPointF)
| Converts a point.
K::Segment_2 | operator() (QLineF)
| Converts a segment.
K::Iso_rectangle_2 | operator() (QRectF)
| Converts an iso rectangle.
void | operator() (std::list< K::Point_2 > &, QPolygonF)
| Converts a polygon to a list of points.
