i ref to this first code and
- -a- made it for me readable and runable in processing IDE
- -b- made a working registered class from it but failed about the key register
so need to still call them from main
- -c- find from G4P a other way to register the key event
-A-

hope the 3 examples might help you with your problem ( also code styling ).
i will test it soon as i found a way to activate keyReleased()
