Hello hpchong7,

It is possible, I did not understand the question, but in this example all is OK:

import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;

public class ListDemo1 extends JFrame {
    public ListDemo1() {
        JPanel screenPane = new JPanel();
        screenPane.add(new JTextArea("Hello world Hello world Hello world"));
        String[] petStrings = { "Bird", "Cat", "Dog", "Rabbit", "Pig" };
        screenPane.add(new JComboBox(petStrings));
    public static void main(String s[]) {
        JFrame frame = new ListDemo1();
        frame.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {System.exit(0);}

Best Regards,
