overriding system function like desktop cube,alt+tab
 

I am developing a game in java and I want it to be in fullscreen mode,so i read the oracle tutorial and got it fullscreen successfully,But I don't want other system functions such as desktop cube,alt+tab etc working when the application in running.
Thanks in advance !

Do you want to avoid from working the key combinations when the game has focus? If that's your problem, I believe it is more a programming issue than anything else.
