Q3CanvasPolygon::Q3CanvasPolygon ( Q3Canvas * canvas )

Constructs a point-less polygon on the canvas canvas. You should call setPoints() before using it further.

Q3CanvasPolygon::~Q3CanvasPolygon ()

Destroys the polygon.

Q3PointArray Q3CanvasPolygon::areaPoints () const [virtual]

Reimplemented from Q3CanvasPolygonalItem::areaPoints().

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().

void Q3CanvasPolygon::drawShape ( QPainter & p ) [virtual protected]

Reimplemented from Q3CanvasPolygonalItem::drawShape().

Draws the polygon using the painter p.

Note that Q3CanvasPolygon does not support an outline (the pen is always NoPen).

void Q3CanvasPolygon::moveBy ( double dx, double dy ) [virtual]

Reimplemented from Q3CanvasItem::moveBy().

Q3PointArray Q3CanvasPolygon::points () const

Returns the vertices of the polygon, not translated by the position.

See also setPoints() and areaPoints().

int Q3CanvasPolygon::rtti () const [virtual]

Reimplemented from Q3CanvasItem::rtti().

Returns 4 (Q3CanvasItem::Rtti_Polygon).

See also Q3CanvasItem::rtti().

void Q3CanvasPolygon::setPoints ( Q3PointArray 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.

See also points().
