Document

Removes newChild from its parent and makes it a child of this node by adding it to the end of this node's child array.

Usage

From source file:MyTreeModelListener.java

public static void main(String args[]) {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root");
    JTree tree = new JTree(root);

    DefaultTreeModel treeModel = new DefaultTreeModel(root);
    treeModel.addTreeModelListener(new MyTreeModelListener());

    treeModel.insertNodeInto(new DefaultMutableTreeNode("A"), root, 0);

    root.add(new DefaultMutableTreeNode("B"));
    root.add(new DefaultMutableTreeNode("C"));

    JScrollPane scrollPane = new JScrollPane(tree);
    frame.add(scrollPane, BorderLayout.CENTER);
    frame.setSize(300, 150);/*from w w w . j av  a2 s.com*/
    frame.setVisible(true);
