      net.wotonomy.ui.EODisplayGroup

              net.wotonomy.ui.swing.MutableDisplayGroupNode

All Implemented Interfaces:

javax.swing.tree.MutableTreeNode, javax.swing.tree.TreeNode, net.wotonomy.control.EOEditingContext.Editor, net.wotonomy.control.EOObserving

public class MutableDisplayGroupNode
extends DisplayGroupNode
implements javax.swing.tree.MutableTreeNode

A DisplayGroupNode that exposes the MutableTreeNode interface. This was required so that other subclasses of DisplayGroupNode could opt out of supporting MutableTreeNode (so that they can implement IlvActivity, for example).
