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