Q3CanvasLine Class Reference
[Qt3Support module]

Detailed Description

The Q3CanvasLine class provides a line on a Q3Canvas.

The line inherits functionality from Q3CanvasPolygonalItem, 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 Q3CanvasItem::move() and Q3CanvasItem::moveBy(), or by setting coordinates with Q3CanvasItem::setX(), Q3CanvasItem::setY() and Q3CanvasItem::setZ().
