keep the rubberband on screen?

Hi,

_From the reference code visad/bom/RubberBandBoxRendererJ3D.java, I am
able to draw a rubber band when I press my right mouse button. But if I
release my right mouse button, the rubber band disappears from the
screen.

Could I be able to keep such rubber band  on the screen until I click on
the screen again at some other place?

Thanks in advance.
