IONGrDrawable / IONJGrDrawable Class

Objects of the IONGrDrawable class represent a drawing area for IDL-produced graphics that can be part of a Java AWT. The IONGrDrawable can act alone as a drawing area or it can contain many IONGrGraphic objects. The way in which multiple Graphic objects are displayed in the drawable can be controlled using setNoErase() and setMulti().
