void | setCapStyle(Qt::PenCapStyle newCapStyle)

Notifier signal:

void | capStyleChanged()

See also Qt::PenCapStyle.

### width : qreal

The width of the spline line in pixels. The default value is 2.0.

Access functions:

qreal | width() const
void | setWidth(qreal newWidth)

Notifier signal:

void | widthChanged()
