private Rectangle getPathBounds(TreePath path, Insets insets, Rectangle bounds) {
    bounds = treeState.getBounds(path, bounds);
    if (bounds != null) {
      bounds.x = 0;
      bounds.y += insets.top;
      bounds.width = tree.getWidth();
    }
    return bounds;
  }
}

//create a tree data structure
 DefaultMutableTreeNode tree = new DefaultMutableTreeNode("root");
 //optional: you can make the tree really big
 //now show the tree
 JFrame frame = new JFrame("TreeDemo");
 frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 //Create a Jtree component to display your data structure 
 JTree treeDisplay = new JTree(tree);
 //expand the tree all out
 for(int i = 0; i < treeDisplay.getRowCount(); i++) {
   treeDisplay.expandRow(i);
 }
 //put your tree display component in a scroll pane
 frame.add(new JScrollPane(treeDisplay));
 //Display the window.
 frame.pack();
 frame.setVisible(true);
 //save tree in the window to a file
 BufferedImage img = new BufferedImage(treeDisplay.getWidth(), treeDisplay.getHeight(), BufferedImage.TYPE_INT_RGB);
 Graphics2D graphics = img.createGraphics();
 //put graphics on the buffered image
 treeDisplay.paintAll(graphics);    
 graphics.dispose();
 try {
   ImageIO.write(img, "png", new File("tree.png"));
 }
 catch (IOException e) {
   e.printStackTrace();
 }
