Hello, I have written a simple program to test KeyEvent and I am having problems. I have created a class that extends JWindow and implements the KeyListener interface, but the JWindow does not seem to ever accept events of any kind. I originally wrote the program at work using WindowsNT and JDK 1.3 and all is good, but when I compile it using ProjectBuilder or command line java in OS X (10.0.2) there are no events registered. Is there a finer point to the OSX event model that I am missing, or is this a bug?

This appears to be a bug in the Java2 implementation on Mac OS X. The best guess is that it's a focus issue that in the past has shown up on unix-based implementations, such as Solaris and Linux. My suspicion is that the Mac OS X implementation is similarly afflicted.

You CAN however get this to work properly with a bit of a hack. I created a test case that has a JFrame as well as a JWindow subclass that implements BOTH KeyListener and MouseListener. You must make the JFrame visible, but you can make it visible off-screen if you wish. I've also had to call requestFocus() in all the MouseListener methods or KeyEvents were still not received.

The test code is a bit long (about 100 lines) so I'd prefer not to post it, but if you'd like me to email just say the word.

Thanks, I needed to know if other people had seen this type of thing. I agree with you that it seems to be a focus problem, and I would like to take a look at the code you've got if it's not to much trouble. My e-mail is boime@interaccess.com

I also just learned that Apple is not supporting the Java3D API quite yet, so this puts a crimp in the project running in Java with true cross platform support. I am considering writing it in C++ now, but it's going to be quite a bit more work writing for Windows and MacOS X than it would have been just using Java. Aplle growing pains I guess. Thanks again.
