java.lang.Objectorg.eclipse.gef.editparts.AbstractEditPart
org.eclipse.gef.editparts.RootTreeEditPart
public class RootTreeEditPart
The root editpart for a TreeViewer
. There is limited control of
a Tree, so this root implementation should work for all purposes. This
implementation does little more than hold onto the viewer, and pass the
Tree
to the contents as its widget.
