public class FreeformGraphicalRootEditPart

extends AbstractGraphicalEditPart

implements RootEditPart, LayerConstants, LayerManager

Provides support for representation of any other graphical EditPart. It contains Layers which are used to represent specific type of visual information. The Layers are (1) Primary - Used to hold the main EditPart's Figures. (2) Connection - Used to hold the connections between EditParts. (3) Handle - Takes care of holding handles for EditParts. (4) Feedback - Shows feedback information for the EditParts.
