[JAVA] Problem med focus, tror jag
Hej, jag vill att mitt program ska stängas ner när jag trycker ner någon tangent. Men det verkar inte funka, och efter lite koll så har jag sett att det är min frame som har focus, men mousemovement funkar endå tydligen och mousepressed verkar funka, det kan dock bero på att den ger focus först när jag trycker på musknappen.
Iallafall finns det något sätt att direkt säga att jag vill att myWindow ska få focus bestämt? Den verkar inte få det fast jag kör myWindow.requestFocus();
