SampleTreeModel

public class SampleTreeModel extends DefaultTreeModel
SampleTreeModel extends JTreeModel to extends valueForPathChanged. This method is called as a result of the user editing a value in the tree. If you allow editing in your tree, are using TreeNodes and the user object of the TreeNodes is not a String, then you're going to have to subclass JTreeModel as this example does.
