50
51The QCanvasLine class provides a line on a <a href="qcanvas.html">QCanvas</a>.
52
53<p>
54
55
56<p> The line inherits functionality from <a href="qcanvaspolygonalitem.html">QCanvasPolygonalItem</a>, for
57example the <a href="qcanvaspolygonalitem.html#setPen">setPen</a>() function. The start and end points of the
58line are set with <a href="#setPoints">setPoints</a>().
59<p> Like any other canvas item lines can be moved with
60<a href="qcanvasitem.html#move">QCanvasItem::move</a>() and <a href="qcanvasitem.html#moveBy">QCanvasItem::moveBy</a>(), or by setting
61coordinates with <a href="qcanvasitem.html#setX">QCanvasItem::setX</a>(), <a href="qcanvasitem.html#setY">QCanvasItem::setY</a>() and
62<a href="qcanvasitem.html#setZ">QCanvasItem::setZ</a>().
