How to link the change to RangeWidget with SelectRangeWidget?

Suppose

RealType vis = RealType.getRealType("VIS");
ScalarMap visMap = new ScalarMap(vis, Display.RGB);
visMap.setRange(-10.0f,10.0f);

ScalarMap visRangeMap = new ScalarMap(vis, Display.SelectRange);
visRangeMap.setRange(-10.0f,10.0f);
.....

JFrame f = new JFrame();

f.getContentPane().add (new RangeWidget(visMap),BorderLayout.NORTH);
f.getContentPane().add (new ColorMapWidget(visMap),BorderLayout.CENTER);

f.getContentPane().add (new
SelectRangeWidget(visRangeMap),BorderLayout.SOUTH);

If I make some change in RangeWidget, i.e. change -10.0f to -5.0f, how
this change be reflected in SelectRangeWidget, that is, the select range
slider will be moved only between -5.0 to 10.0

Thanks,
