java - Button for closing a JDialog

Question

I want to add a button (JButton) at the bottom of a JDialog which should close the JDialog when pressed. The problem is I don't know what to write in the ActionListener of that button. I don't want the button to exit the program, just close the dialog.

The JDialog is created by explicitly calling one of JDialog's constructors, not by calling one of the methods from JOptionPane.

I was extremely surprised that I was unable to find an answer to this using Google. I expected that a problem that is so often encoutered would be widely covered on a lot of programming sites. Pretty weird that it is not.

Answer 1

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

public class YourDialog extends JDialog implements ActionListener {

  JButton button;

  public YourDialog() {
     button = new JButton("Close");
     button.addActionListener(this);
     add(button);
     pack();
     setVisible(true);
  }

  public void actionPerformed(ActionEvent e) {
      dispose();
  }
}

• close only dialolg using dispose() method parent frame not closed. reason that JVM not terminated.
