public voidinsertNodeInto(javax.swing.tree.MutableTreeNode child, javax.swing.tree.MutableTreeNode parent)

    int index = findIndexFor(child, parent);
    super.insertNodeInto(child, parent, index);
public voidinsertNodeInto(javax.swing.tree.MutableTreeNode child, javax.swing.tree.MutableTreeNode par, int i)

    // The index is useless in this model, so just ignore it.
