Closing AWT Frame and Terminating Application
This section provides solutions and sample program on how to close an AWT frame and terminate the application.
Problem: I have a frame window displayed on the screen and I want to close the frame and terminate the application, when user invokes the close command from the window's system menu, or clicks on the close icon from the window's system icon list.
Solution: You can create a new window event listener class and add an object of this listener class to the Frame object. In the new window event listener, you can implement your owner version of windowClosing() handler method. Of course, the quickest way to create a new window event listener class is to extend the WindowAdapter class.
The following sample code, FrameClose.java, shows you how to do this.
/* FrameClose.java * Copyright (c) 1997-2024 HerongYang.com. All Rights Reserved. */ import java.awt.Frame; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; public class FrameClose { public static void main(String[] a) { Frame f = new Frame(); f.setTitle("Closing Frame with Window Listener"); f.setBounds(100,50,500,300); f.addWindowListener(new MyWindowListener()); f.setVisible(true); } static class MyWindowListener extends WindowAdapter { public void windowClosing(WindowEvent e) { System.exit(0); } } }
