.SH DESCRIPTION
The TQCanvasPolygon class provides a polygon on a TQCanvas.
.PP
Paints a polygon with a TQBrush. 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.
.PP
The polygon can be drawn on a painter with drawShape().
.PP
Like any other canvas item polygons can be moved with TQCanvasItem::move() and TQCanvasItem::moveBy(), or by setting coordinates with TQCanvasItem::setX(), TQCanvasItem::setY() and TQCanvasItem::setZ().
.PP
Note: TQCanvasPolygon does not use the pen.
.PP
See also Graphics Classes and Image Processing Classes.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "TQCanvasPolygon::TQCanvasPolygon ( TQCanvas * canvas )"
Constructs a point-less polygon on the canvas \fIcanvas\fR. You should call setPoints() before using it further.
.SH "TQCanvasPolygon::~TQCanvasPolygon ()"
Destroys the polygon.
.SH "QPointArray TQCanvasPolygon::areaPoints () const\fC [virtual]\fR"
Returns the vertices of the polygon translated by the polygon's current x(), y() position, i.e. relative to the canvas's origin.
.PP
See also setPoints() and points().
.PP
Reimplemented from TQCanvasPolygonalItem.
.SH "void TQCanvasPolygon::drawShape ( TQPainter & p )\fC [virtual protected]\fR"
Draws the polygon using the painter \fIp\fR.
.PP
Note that TQCanvasPolygon does not support an outline (the pen is always NoPen).
.PP
Reimplemented from TQCanvasPolygonalItem.
.SH "QPointArray TQCanvasPolygon::points () const"
Returns the vertices of the polygon, not translated by the position.
.PP
See also setPoints() and areaPoints().
.SH "int TQCanvasPolygon::rtti () const\fC [virtual]\fR"
Returns 4 (TQCanvasItem::Rtti_Polygon).
.PP
See also TQCanvasItem::rtti().
.PP
Reimplemented from TQCanvasPolygonalItem.
.PP
Reimplemented in TQCanvasSpline.
.SH "void TQCanvasPolygon::setPoints ( QPointArray pa )"
Sets the points of the polygon to be \fIpa\fR. These points will have
their x and y coordinates automatically translated by x(), y() as
the polygon is moved.
