`#include <CGAL/Qt/PainterOstream.h>`

## Definition

An object of type `PainterOstream` provides output operators for `Kernel` objects.

As CGAL has unbounded objects the `PainterOstream` must be constructed with a clipping rectangle. This is typically the visible area of the widget where the unbounded object is displayed.

## Creation
| PainterOstream (QPainter *qp, QRectF clippingRect)
| The clipping rect is used for unbounded `Kernel` objects.

## Operations
PainterOstream< K > | operator<< (K::Point_2)
| Draws a point.
PainterOstream< K > | operator<< (K::Segment_2)
| Draws a segment.
PainterOstream< K > | operator<< (K::Ray_2)
| Draws a clipped ray.
PainterOstream< K > | operator<< (K::Line_2)
| Draws a clipped line.
PainterOstream< K > | operator<< (K::Triangle_2)
| Draws a triangle.
PainterOstream< K > | operator<< (K::Iso_rectangle_2)
| Draws an iso rectangle.
PainterOstream< K > | operator<< (K::Circle_2)
| Draws a circle.
PainterOstream< K > | operator<< (K::Circular_arc_2)
| Draws a circular arc.
PainterOstream< K > | operator<< (std::list< K::Point_2 >)
| Draws a polyline. More...
PainterOstream< K > | operator<< (Bbox_2)
| Draws an iso rectangle.
PainterOstream< K > | operator<< (QPen)
| Sets the pen used in the next paint operations.
PainterOstream< K > | operator<< (QBrush)
| Sets the brush used in the next paint operations.

## Member Function Documentation

template<typename K >

PainterOstream<K> CGAL::Qt::PainterOstream< K >::operator<< | ( | std::list< K::Point_2 > | ) |  |

Draws a polyline.

In order to close it the first and last point must be equal.
