The easiest way to do this with a RealTuple object linked
to multiple displays via direct manipulation DataRenderers.
visad/examples/Test00.java provides an example. The RealTuple
objects is depicted as the small purple square in the lower
left corner of bothdisplays. You can drag it with a right
mouse button click in either display.
To depict a RealTuple as a cross hair, see the two yellow
direct manipulation cursors in visad/examples/Test27.java.
The alternative is to link a DisplayListener to your
Display that listens for center mouse button DisplayEvents
and uses them to generate depictions in other displays.
This would be more work.
Cheers,
Bill
