Create a Object2dDisplay, give it a Raster widget to draw on, a Discrete2d, a message to call on each object, and (optionally) a collection of objects and it will dispatch the message to all objects with the Raster widget as an argument. In addition, Object2dDisplay can help you make probees.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ========
