Hi,

I'm developing an editor where I need realtime (horizontal) scrolling.
My approach so far ist a Thread that updates the Viewport position of
the GraphicalViewer every 20ms.

FigureCanvas canvas =
((FigureCanvas)(getGraphicalViewer().getControl()));

Viewport viewPort = canvas.getViewport();
viewPort.setHorizontalLocation((int) position);

The drawing is not very smooth. However when manually scrolling it
seems much faster and my CPU usage isn't very high either.

Is there a better way to do this?

Thanks.

Best Regards,
Fabian
