It's not specific to Java, it happens with any application, as applications grab input while showing menus, preventing KWin from keyboard access. When I open any menu of any KDE application I can press Alt+Tab and it works like expected. I also gave "The Evil Operating System" a short visit and tested there. It works like expected even with open menus in Java applications. There is something wrong, incomplete or incompatible within the group of X, KDE and Java on Linux. I would be glad if you could sit together (e.g. with the people from Sun) and resolve this bug. I couldn't run the example you provided, but I ran Pipe (the petrinet editor) but could not reproduce your problem. The Alt-Tab menu just shows fine. I also tried Pipe and can reproduce the problem with the following simple steps: 1) start Pipe 2) press Alt+F to open the file menu 3) press Alt+TAB 4) notice that nothing happens @Bram: do you reach (4) when following this steps? I can only reproduce when first pressing Tab and then Alt, but all works OK when pressing Alt and then Tab. And I think the latter method is the usual method of Alt+Tab. I would like to reproduce your success. What distribution and Java version do you use? I am using an up-to-date Debian testing system and $ java -version java version "1.6.0_02" Java(TM) SE Runtime Environment (build 1.6.0_02-b05) Java HotSpot(TM) Client VM (build 1.6.0_02-b05, mixed mode, sharing) BTW: TAB+Alt does not work for me at all. I never tried this before. Should this work like Alt+TAB? Gentoo Linux, Java 1.5.0.12 . So it could have been a change in the toolkit then. I'm quite unsure this is an exclusive KWin bug, you may try another window manager, like Gnome's, to see if it happens too.
> Should this work like Alt+TAB?
Don't think so, though. So never mind that combo.
I also tried now Java 1.5.0.12 and... it works! Thank you very much SUN for another regression in your complete mess that is Swing on X! ;-( Re-closing then. Thanks for confirming it's not a kwin issue. Sun says it is not their fault. Please see here: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6589189 Could you please reopen the bug and get together with Sun to resolve the issue? OK, Bug reopened. *** This bug has been marked as a duplicate of 70063 *** |
