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 Q3CanvasItem::move() and Q3CanvasItem::moveBy(), or by setting coordinates with Q3CanvasItem::setX(), Q3CanvasItem::setY() and Q3CanvasItem::setZ().
Note: Q3CanvasPolygon does not use the pen.
Member Function Documentation
Q3CanvasPolygon::Q3CanvasPolygon(Q3Canvas * canvas)
Constructs a point-less polygon on the canvas canvas. You should call setPoints() before using it further.
Destroys the polygon.
[virtual] Q3PointArray Q3CanvasPolygon::areaPoints() const
Reimplemented from Q3CanvasPolygonalItem::areaPoints().
[virtual protected] void Q3CanvasPolygon::drawShape(QPainter & p)
Reimplemented from Q3CanvasPolygonalItem::drawShape().
Draws the polygon using the painter p.
Note that Q3CanvasPolygon does not support an outline (the pen is always NoPen).
Reimplemented from Q3CanvasItem::moveBy().
Q3PointArray Q3CanvasPolygon::points() const
Returns the vertices of the polygon, not translated by the position.
Reimplemented from Q3CanvasItem::rtti().
Returns 4 (Q3CanvasItem::Rtti_Polygon).
See also Q3CanvasItem::rtti().
void Q3CanvasPolygon::setPoints(Q3PointArray pa)
See also points().
