DESCRIPTION
The QCanvasPolygon class provides a polygon on a QCanvas.
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
QCanvasItem::move() and QCanvasItem::moveBy(), or by setting
coordinates with QCanvasItem::setX(), QCanvasItem::setY() and
QCanvasItem::setZ().
Note: QCanvasPolygon does not use the pen.
See also Graphics Classes and Image Processing Classes.
MEMBER FUNCTION DOCUMENTATIONQCanvasPolygon::QCanvasPolygon ( QCanvas * canvas )
Constructs a point-less polygon on the canvas canvas. You should call
setPoints() before using it further.
QCanvasPolygon::~QCanvasPolygon ()
Destroys the polygon.
QPointArray QCanvasPolygon::areaPoints () const [virtual]
Returns the vertices of the polygon translated by the polygon's current
x(), y() position, i.e. relative to the canvas's origin.
See also setPoints() and points().
Reimplemented from QCanvasPolygonalItem.
void QCanvasPolygon::drawShape ( QPainter & p ) [virtual protected]
Draws the polygon using the painter p.
Note that QCanvasPolygon does not support an outline (the pen is always
NoPen).
Reimplemented from QCanvasPolygonalItem.
QPointArray QCanvasPolygon::points () const
Returns the vertices of the polygon, not translated by the position.
See also setPoints() and areaPoints().
int QCanvasPolygon::rtti () const [virtual]
Returns 4 (QCanvasItem::Rtti_Polygon).
See also QCanvasItem::rtti().
Reimplemented from QCanvasPolygonalItem.
Reimplemented in QCanvasSpline.
void QCanvasPolygon::setPoints ( QPointArray pa )
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.
