public class GraphicalElement

extends RGO

Graphical objects that can contain other graphical objects.

This class adds to the rectangular graphical object several concepts to help in the construction of general objects:

• the addGraphicalObject method builds up this object from simpler objects;
• the X and Y Scale properties specify the co-ordinate scales for native units for this object.
