FileDialog error :o(

Question

Can someone please help me? I'm not sure why the class "OpenDialogFile" below is not working. I really appreciate your help.
I got this following error:
ChatClient.java:66: cannot resolve symbol
symbol : constructor FileDialog (ChatClient.OpenDialogFile,java.lang.String,int
location: class java.awt.FileDialog
fd = new FileDialog(this, "OPEN", FileDialog.LOAD);
Here is my code:
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class ChatClient {
private TextArea output;
private TextField input;
private Button sendButton;
private Button quitButton;
private Button openFileButton;
public FileDialog fd;
public ChatClient() {
output = new TextArea(10,50);
input = new TextField(50);
sendButton = new Button("Send");
quitButton = new Button("Quit");
openFileButton = new Button("Open File");
public void launchFrame() {
Frame frame = new Frame("Chat Room");
frame.setLayout(new BorderLayout());
frame.add(output,BorderLayout.WEST);
frame.add(input,BorderLayout.SOUTH);
Panel p1 = new Panel();
p1.add(sendButton);
p1.add(quitButton);
p1.add(openFileButton);
frame.add(p1,BorderLayout.CENTER);
// Attach listener to the appropriate components
sendButton.addActionListener(new SendHandler());
frame.addWindowListener(new CloseHandler());
input.addActionListener(new InputHandler());
quitButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.exit(0);
openFileButton.addActionListener(new OpenDialogFile());
frame.pack();
frame.setVisible(true);
private void copyText() {
String text = input.getText();
output.setText(output.getText()+text+"\n");
input.setText("");
private class SendHandler implements ActionListener {
public void actionPerformed(ActionEvent e) {
copyText();
private class OpenDialogFile implements ActionListener {
public void actionPerformed(ActionEvent e) {
     fd = new FileDialog(this, "OPEN", FileDialog.LOAD);
     fd.show();
private class CloseHandler extends WindowAdapter {
public void windowClosing(WindowEvent e) {
System.exit(0);
private class InputHandler implements ActionListener {
public void actionPerformed(ActionEvent e) {
copyText();
public static void main(String[] args) {
ChatClient c = new ChatClient();
c.launchFrame();
}

All constructors for FileDialog require an instance of Frame as a parent. ChatClient.OpenFileDialog apparently doesn't meet this requirement hence compiler is complaining.
