DESCRIPTION

27       The QCanvasPolygon class provides a polygon on a QCanvas.
28
29       Paints a polygon with a QBrush. The polygon's points can be set in the
30       constructor or set or changed later using setPoints(). Use points() to
31       retrieve the points, or areaPoints() to retrieve the points relative to
32       the canvas's origin.
33
34       The polygon can be drawn on a painter with drawShape().
35
36       Like any other canvas item polygons can be moved with
37       QCanvasItem::move() and QCanvasItem::moveBy(), or by setting
38       coordinates with QCanvasItem::setX(), QCanvasItem::setY() and
39       QCanvasItem::setZ().
40
41       Note: QCanvasPolygon does not use the pen.

MEMBER FUNCTION DOCUMENTATION

QCanvasPolygon::QCanvasPolygon ( QCanvas * canvas )

47       Constructs a point-less polygon on the canvas canvas. You should call
48       setPoints() before using it further.
49

QCanvasPolygon::~QCanvasPolygon ()

51       Destroys the polygon.
52

QPointArray QCanvasPolygon::areaPoints () const [virtual]

54       Returns the vertices of the polygon translated by the polygon's current
55       x(), y() position, i.e. relative to the canvas's origin.
56
57       See also setPoints() and points().
58
59       Reimplemented from QCanvasPolygonalItem.
60

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

62       Draws the polygon using the painter p.
63
64       Note that QCanvasPolygon does not support an outline (the pen is always
65       NoPen).
66
67       Reimplemented from QCanvasPolygonalItem.
68

QPointArray QCanvasPolygon::points () const

70       Returns the vertices of the polygon, not translated by the position.
71
72       See also setPoints() and areaPoints().
73

int QCanvasPolygon::rtti () const [virtual]

75       Returns 4 (QCanvasItem::Rtti_Polygon).
76
77       See also QCanvasItem::rtti().
78
79       Reimplemented from QCanvasPolygonalItem.
80
81       Reimplemented in QCanvasSpline.
82

void QCanvasPolygon::setPoints ( QPointArray pa )

84       Sets the points of the polygon to be pa. These points will have their x
85       and y coordinates automatically translated by x(), y() as the polygon
86       is moved.
