Description Horcrux7 2006-11-09 22:19:47 UTC
If I run the small test below then I receive with the Sun VM the follow output and the JFrame is closed. With GNU classpath there are no output and the JFrame is not closed. I have not tested if this is also a problem of other Window classes. The WindowEvents will also not dispatched if I add a WindowListener.

Sun output
java.awt.event.WindowEvent[WINDOW_ACTIVATED,opposite=null,oldState=0,newState=0] on frame0
java.awt.event.WindowEvent[WINDOW_OPENED,opposite=null,oldState=0,newState=0] on frame0
java.awt.event.WindowEvent[WINDOW_CLOSING,opposite=null,oldState=0,newState=0] on frame0
java.awt.event.WindowEvent[WINDOW_DEACTIVATED,opposite=null,oldState=0,newState=0] on frame0

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

public class Test{

	public static void main(String[] args){
		final MyFrame jframe = new MyFrame();
        jframe.dispatchEvent(new WindowEvent(jframe, WindowEvent.WINDOW_CLOSING));
    static class MyFrame extends JFrame{
        protected void processEvent(AWTEvent evt){
            System.out.println( evt );
            super.processEvent( evt );

I'll look at this one as I have reworked AWT event handling lately.

I tested this with current CVS HEAD, where it seems to work. Is it possible that you retest it with the current CVS version (you can download a snapshot from http://builder.classpath.org/dist/)? Otherwise I'll close this bug.

I have retest it with the current CVS version and it work now. Sorry for your time that I use.

Thanks for retesting!
