How to change TreeControl's icons?

Question

I add the following line to jbInit()
((TreeControl.TreeControlTree.TreeControlNodeRenderer)(treeControl1.getTree).getCellRenderer))).
setLeafIcon(new ImageIcon"e:/images/middle.gif"));
It's no work.
Thank you!

The answer is the following code:
private class MyRenderer extends DefaultTreeCellRenderer {
ImageIcon tutorialIcon;
public MyRenderer() {
tutorialIcon = new ImageIcon("kongimgs/cloud.gif");
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);
if (leaf) {
setIcon(new ImageIcon("kongimgs/note1.gif"));
setToolTipText("This is person.");
} else {
setToolTipText(null);
if (leaf && hasFocus)
setIcon(new ImageIcon("kongimgs/point.gif"));
Object _root=tree.getModel().getRoot();
if (null==_root)
System.out.println("root=null");
if (value.equals(_root))
setIcon(new ImageIcon("kongimgs/home.gif"));
//? if (((DefaultMutableTreeNode)value).getParent().equals(_root))
//setIcon(new ImageIcon("kongimgs/plus.gif"));
String str =((TreeControlNode)value).getName();
int index = str.lastIndexOf("-GW");
if (index >0) {
setToolTipText("This is Gateway.");
setIcon(tutorialIcon);
index = str.lastIndexOf("test");
if (index ==0) {
setToolTipText("This is Link.");
setIcon(new ImageIcon("kongimgs/link.gif"));
return this;
JTree _tree =treeControl1.getTree();
_tree.setRowHeight(-1);
_tree.setCellRenderer(new MyRenderer());
null
