.SH DESCRIPTION
|
||
|
|
The QCanvasLine class provides a line on a QCanvas.
|
||
|
|
.PP
|
||
|
|
The line inherits functionality from QCanvasPolygonalItem, 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 QCanvasItem::move() and QCanvasItem::moveBy(), or by setting coordinates with QCanvasItem::setX(), QCanvasItem::setY() and QCanvasItem::setZ().
|
||
|
|
