Traversal of custom item menu icons in form

Question

Here is one doubt for me
me created one menu design with customitem subclass creating background image with sprite class and menu icons over it as in mobile(grid view) using default method paint() g.drawImage();
and then appended this customitem to form. Now the problem is how to traverse among the custom item menu icons.
i am aware of traverse() and traverout() methods, but don't know how to enable it
Pls suggest me expecting a positive reply
Thanks

import java.util.Vector;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.*;
import javax.microedition.io.*;
import java.io.*;
public class IconsTester implements CommandListener, ItemStateListener {
private Display display;
private Form mainForm;
private ChoiceGroup optionsGroup;
private int itemNum;
private Command CMD_NEXT= new Command("Next", Command.ITEM,
2);
private Command CMD_BACK= new Command("Back", Command.BACK,
1);
private Image newApp = null;
private Image viewApp = null;
private Image cancelApp = null;
public IconsTester(Display d, Form backF)
display = d;
mainForm = new Form("Appointments");
mainForm.append("Choose an action to be performed: ");
Image[] imageArray = null;
try {
newApp = Image.createImage("/success.png");
viewApp = Image.createImage("/search.png");
cancelApp = Image.createImage("/time.png");
imageArray = new Image[] { newApp, viewApp, cancelApp };
catch (java.io.IOException err) {
System.out.println(err);
mainForm.append(new Spacer(40,40));
mainForm.append(newApp);
mainForm.append(new Spacer(40,40));
mainForm.append(viewApp);
mainForm.append(new Spacer(40,40));
mainForm.append(cancelApp);*/
mainForm.addCommand(CMD_BACK);
mainForm.addCommand(CMD_NEXT);
mainForm.setCommandListener(this);
mainForm.setItemStateListener(this);
display.setCurrent(mainForm);
public void commandAction(Command c, Displayable s) {
if (c == CMD_BACK) {
display.setCurrent(Login.list);
else
mainForm.setItemStateListener(this);
public void itemStateChanged(Item item)
if( item.equals(newApp))
{    itemNum = 0;
new NewAppointment(display, mainForm);
else if( item.equals(viewApp))
{    itemNum = 2;
new NewAppointment(display, mainForm);
else if( item.equals(cancelApp))
{    itemNum = 1;
new NewAppointment(display, mainForm);
}
