.SH DESCRIPTION
The TQCanvasLine class provides a line on a TQCanvas.
.PP
The line inherits functionality from TQCanvasPolygonalItem, for example the setPen() function. The start and end points of the line are set with setPoints().
.PP
Like any other canvas item lines can be moved with TQCanvasItem::move() and TQCanvasItem::moveBy(), or by setting coordinates with TQCanvasItem::setX(), TQCanvasItem::setY() and TQCanvasItem::setZ().
.PP
See also Graphics Classes and Image Processing Classes.
