This command ungroups a group view. It reparents the children of the group so that their parent is the group's parent and it deletes the group view. The children's locations are also changed to be relative to the location of their new parent.

Since:
2.1

Constructor Summary
UngroupCommand (org.eclipse.emf.transaction.TransactionalEditingDomain editingDomain, Node groupView)
          Creates a new instance.
