The below example (from vogella.de) explains how manual node movement can be disabled for a graph. Is this also possible for just a set of nodes, e.g., by extending GraphNode? And how could this work?

Many thanks!

public class NonMovableGraph extends Graph {

	public NonMovableGraph(Composite parent, int style) {
		super(parent, style);
		this.getLightweightSystem().setEventDispatcher(
				new SWTEventDispatcher() {
					public void dispatchMouseMoved(
							org.eclipse.swt.events.MouseEvent me) {
						// Doing nothing
					}
				});
	}

}
