Member Function Documentation

QCanvasPolygon::QCanvasPolygon ( QCanvas * canvas )

Constructs a pointless polygon on canvas. You should call setPoints() before using it further.

QCanvasPolygon::~QCanvasPolygon ()

Destructs the polygon.

QPointArray QCanvasPolygon::areaPoints () const [virtual]

Returns the vertices of the polygon translated by the x(), y() position.

See also setPoints() and points().

Reimplemented from QCanvasPolygonalItem.

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

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

Reimplemented from QCanvasPolygonalItem.

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

Reimplemented for internal reasons; the API is not affected.

Reimplemented from QCanvasItem.

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.

See also QCanvasItem::rtti().

Reimplemented from QCanvasItem.

void QCanvasPolygon::setPoints ( QPointArray pa )

Sets the points of the polygon to be pa, which will be translated by x(), y() as the polygon is moved.
