.SH DESCRIPTION
A polygon with a movable reference point.
.PP
Paints a polygon in a QBrush.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QCanvasPolygon::QCanvasPolygon ( QCanvas * canvas )"
Constructs a pointless polygon on \fIcanvas.\fR You should call setPoints() before using it further.
.SH "QCanvasPolygon::~QCanvasPolygon ()"
Destructs the polygon.
.SH "QPointArray QCanvasPolygon::areaPoints () const \fC[virtual]\fR"
Returns the vertices of the polygon translated by the x(), y() position.
.PP
See also setPoints() and points().
.PP
Reimplemented from QCanvasPolygonalItem.
.SH "void QCanvasPolygon::drawShape ( QPainter & p ) \fC[virtual protected]\fR"
Note that QCanvasPolygon does not support an outline (pen is always NoPen).
.PP
Reimplemented from QCanvasPolygonalItem.
.SH "void QCanvasPolygon::moveBy ( double dx, double dy ) \fC[virtual]\fR"
Reimplemented for internal reasons; the API is not affected.
.PP
Reimplemented from QCanvasItem.
.SH "QPointArray QCanvasPolygon::points () const"
Returns the vertices of the polygon, not translated by the position.
.PP
See also setPoints() and areaPoints().
.SH "int QCanvasPolygon::rtti () const \fC[virtual]\fR"
Returns 4.
.PP
See also QCanvasItem::rtti().
.PP
Reimplemented from QCanvasItem.
.SH "void QCanvasPolygon::setPoints ( QPointArray pa )"
Sets the points of the polygon to be \fIpa,\fR which will be translated
by x(), y() as the polygon is moved.
