Hi Helen,
You could retrieve the coordinates of the rubberband when the mouse
button is released with the help of a CellImpls doAction() method. Then
you could construct a Gridded2DSet with these coordinates and add it to
your display. The problem would be to remove this Gridded2DSet when the
mouse button is pressed once again. Nevertheless it would be no problem
to remove the set when the user finishes drawing another rubberband
since you could then remove the old set in your doAction() and add the
new set.
I did not try this but I think it would work. If you need further help
please ask.
Cheers, Mathias
