tree.putClientProperty("JTree.lineStyle", "none");class MyRenderer extends DefaultTreeCellRenderer {
    Icon tutorialIcon;    public MyRenderer(Icon icon) {
        tutorialIcon = icon;
    }    public Component getTreeCellRendererComponent(
                        JTree tree,
                        Object value,
                        boolean sel,
                        boolean expanded,
                        boolean leaf,
                        int row,
                        boolean hasFocus) {        super.getTreeCellRendererComponent(
                        tree, value, sel,
                        expanded, leaf, row,
                        hasFocus);
  //根据row和column设置icon,根据value设置返回值
            setIcon(tutorialIcon);
            setToolTipText((String)value);
 
        return this;
    }
}tree.setCellRenderer(new MyRenderer(icon));
