#1567 — Focus problem under Linux

  To: comp.lang.java.gui
I've got a JApplet that is having a focus problem.  The URL is 
http://www.knutejohnson.com/chat.html.  After you hit the 'Connect' 
button and enter a handle the focus should transfer to the outgoing 
message JTextField.  This works fine under Winblows but under Fedora 7 
and Mozilla or Ubuntu and Mozilla focus cannot be given to the 
JTextField.  If you minimize/maximize the window though it works fine. 
The source code is available on the page.  I've tried to make an SSCCE 
to duplicate the problem but I can't get it to fail.  Any ideas would be 
greatly appreciated.

Thanks,

Applets, browser VM's, focus (shudder).

You have your work cut out, getting focus to work 
in a consistent and sensible way in an x-plat, 
x-browser manner.

I only have Windows to test on, and while I failed
to see the problem in Mozilla and IE, I failed to see
the *applet* (at all) in Opera - it said 'Loading applet..' 
and did not report errors, but the applet never appeared.

Launch the applet using web start, to get a more 
reliable and predictable focus environment.
