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().
See also Graphics Classes and Image Processing Classes.
