DESCRIPTION

22       The QCanvasLine class provides a line on a QCanvas.
23
24       The line inherits functionality from QCanvasPolygonalItem, for example
25       the setPen() function. The start and end points of the line are set
26       with setPoints().
27
28       Like any other canvas item lines can be moved with QCanvasItem::move()
29       and QCanvasItem::moveBy(), or by setting coordinates with
30       QCanvasItem::setX(), QCanvasItem::setY() and QCanvasItem::setZ().
