QwtPlotCurve: How can i disable antialiasing?

[johno]

Hello,

if i have enabled antialiasing on a QwtPlotCurve() like:

curve = new QwtPlotCurve();
curve->setRenderHint(QwtPlotItem::RenderAntialiased);

curve = new QwtPlotCurve();
curve->setRenderHint(QwtPlotItem::RenderAntialiased);

To copy to clipboard, switch view to plain text mode 

How can i disable it again?

Thank you for an answer!
