Question regarding the keypad of mobile

[rajan701v]

I want the user to restrict the input of some keys on keypad..
Actually i'm using Nokia 6220 Classic phone for development... How do i get the keyid of every key of keypad.. I'm using LWUIT in my application....

One more question???

when the user exits the application or MIDLET, the user is to be restricted and application shows message like "Do u want to exit the application" ? If yes, then exits the application and if No, remain there in the application..

You can do the required by overwriting the keypressed(int key) method of the current LWUIT displayable on the screen and do the needful w/o passing it to the supper in case you want to capture a key.

Thanks for the reply...
What's the problem with this code :

package hello;

import com.sun.lwuit.Component;
import com.sun.lwuit.Display;
import com.sun.lwuit.Form;
import com.sun.lwuit.Label;
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Displayable;
import javax.microedition.midlet.*;

/**
 * @author java
 */
public class KeyPadMidlet extends MIDlet implements CommandListener {

    Display display = null;
    Form form = null;
    Label lbl = null;

    public void startApp() {
        display = Display.getInstance();
        Display.init(this);
        form = new Form("KEY FORM");
        lbl = new Label();
        form.show();
        form.addComponent(lbl);
        form.addComponent(null, new keyListener(true));

    }

    public void pauseApp() {
    }

    public void destroyApp(boolean unconditional) {
        notifyDestroyed();
    }

    public void commandAction(Command cmnd, Displayable dsplbl) {
    }

    class keyListener extends Component {
        boolean fl = false;

        public keyListener(boolean flag) {
            this.fl = flag;
        }

        public void keyPressed(int keycode) {
            if(fl==true){
            super.keyPressed(keycode);
            int k_code = Display.getInstance().getKeyCode(keycode);
            switch (k_code) {
                case Display.GAME_UP:
                    lbl.setText("" + k_code);
                    break;

                case Display.GAME_DOWN:
                    lbl.setText("" + k_code);
                    break;
                default:
                    break;
            }
        }}
    }
} 

It is not printing the keycode value to the label. And how will i get the keycode values for 1to 9 keys.
