From source file:TreeNodeVector.java

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

    Vector<String> v1 = new TreeNodeVector<String>("Two", new String[] { "Mercury", "Venus", "Mars" });
    Vector<Object> v2 = new TreeNodeVector<Object>("Three");
    v2.add(System.getProperties());
    v2.add(v1);//from  ww  w. ja va  2s  .c  o  m
    Object rootNodes[] = { v1, v2 };
    Vector<Object> rootVector = new TreeNodeVector<Object>("Root", rootNodes);
    JTree tree = new JTree(rootVector);
    frame.add(new JScrollPane(tree), BorderLayout.CENTER);

    tree.expandRow(1);
    tree.scrollRowToVisible(2);

    tree.revalidate();

    frame.setSize(300, 300);
