Yes. Define a class that implements the ScalarMapListener
interface. It must implement the
controlChanged(ScalarMapControlEvent evt) method, which
can do nothing, and the mapChanged(ScalarMapEvent evt)
method, which should test for evt.getId() =
ScalarMapEvent.AUTO_SCALE or == ScalarMapEvent.MANUAL.
When it find such an event, invoke your code to copy
ranges from visMap to visRangeMap.
You pass an instance of your class to the
visMap.addScalarMapListener(ScalarMapListener listener)
method.
Good luck,
Bill
