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 ---------------------------------------------------------- Bill Hibbard, SSEC, 1225 W.
