#include <QtCanvasPolygon>
Inherits QtCanvasPolygonalItem.
Inherited by QtCanvasSpline.
The QtCanvasPolygon class provides a polygon on a QtCanvas.
Paints a polygon with a QBrush. The polygon's points can be set in the constructor or set or changed later using setPoints(). Use points() to retrieve the points, or areaPoints() to retrieve the points relative to the canvas's origin.
The polygon can be drawn on a painter with drawShape().
Like any other canvas item polygons can be moved with QtCanvasItem::move() and QtCanvasItem::moveBy(), or by setting coordinates with QtCanvasItem::setX(), QtCanvasItem::setY() and QtCanvasItem::setZ().
Note: QtCanvasPolygon does not use the pen.
Constructs a point-less polygon on the canvas canvas. You should call setPoints() before using it further.
Destroys the polygon.
Returns the vertices of the polygon translated by the polygon's current x(), y() position, i.e. relative to the canvas's origin.
Reimplemented from QtCanvasPolygonalItem.
See also setPoints() and points().
Draws the polygon using the painter p.
Note that QtCanvasPolygon does not support an outline (the pen is always NoPen).
Reimplemented from QtCanvasPolygonalItem.
Returns the vertices of the polygon, not translated by the position.
See also setPoints() and areaPoints().
Returns 4 (QtCanvasItem::Rtti_Polygon).
Reimplemented from QtCanvasItem.
See also QtCanvasItem::rtti().
Sets the points of the polygon to be pa. These points will have their x and y coordinates automatically translated by x(), y() as the polygon is moved.
See also points().
