Bubble Breaker 게임의 거품과 일치하도록 배경색과 ICON이 무작위로 할당 된 JLabel 격자가 있으므로 findComponentAt (getX(), getY()를 사용하면 문제가 발생합니다.))를 클릭하여 구성 요소가 메신저를 얻을 .... 이것은 어떤 레이블을 내가 클릭하고 ICON을 다른 ICON으로 변경하려고하지만 구성 요소 API에 setIcon() 메소드가없는 것 같기 때문에 ICON을 어떻게 바꿀 수 있었는지에 대한 제안?구성 요소에서 JLabel ICON 변경
내 파일은 아래에 나와 있습니다.하지만 난 아직도 분명히 개발 중이므로 지저분합니다. 너무 미안합니다. 구성 요소가 instanceof 연산자를 통해 JLabel의 인 경우
