There are two good examples of doing this in the visad/bom
package. In visad/bom/FlexibleTrackManipulation.java see
the class AnimationControlListener which extends ControlListener.
It gets the 'current' time step from the AnimationControl and
uses it to select a Data object and pass it to setData, as:
track_refs[0].setData(tuples[current]);
In visad/bom/CollectiveBarbManipulation.java see the class
AnimationControlListener which extends ControlListener. It
triggers a CellImpl via a setData(null) on stepper_ref, which
is linked to the Stepper extension of CellImpl. The doAction()
of the CellImpl gets the 'current' time step from the
AnimationControl and uses it to select a Data object and pass
it to setData().
The solution in FlexibleTrackManipulation.java is simpler and
is the one you should folow.
Good luck,
Bill
