public class IlvGraphicGroup
extends IlvGraphicSet

The class IlvGraphicGroup is a subclass of IlvGraphicSet that encapsulates an IlvGroup.

When an IlvGroup is encapsulated in an IlvGraphicGroup, the graphic elements in the group are under the control of the IlvGraphicGroup object. In particular, they are drawn by the IlvGraphicGroup object, not by the manager.

The IlvGraphicGroup class uses the layer property of the graphic elements to draw them in the correct order.

Also, the visible property of the graphic elements is taken into account. The graphic group draws only the graphic elements that are set as visible.

This class is different from the IlvGroupFrame class. An IlvGroupFrame merely provides visual feedback for selecting a group controlled directly by a manager, whereas an IlvGraphicGroup actually contains the graphic elements.
