NAME

       QCanvasPolygon - Polygon on a QCanvas

SYNOPSIS

       #include <qcanvas.h>

       Inherits QCanvasPolygonalItem.

       Inherited by QCanvasSpline.

   Public Members
       QCanvasPolygon ( QCanvas * canvas )
       ~QCanvasPolygon ()
       void setPoints ( QPointArray pa )
       QPointArray points () const
       virtual QPointArray areaPoints () const
       virtual int rtti () const

   Protected Members
       virtual void drawShape ( QPainter & p )

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 DOCUMENTATION

QCanvasPolygon::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.
