린애의 IT 잡아먹기

▶ .setVisibility(View.GONE) 

영역 자체를 없애므로 현재 뷰어나 컨트롤을 전부 없앰.

▶ .setVisibility(View.INVISIBLE)

현재 설정 영역은 그대로 두고 표시하지 않음.

▶ .setVisibility(View.VISIBLE)

현재 설정 영역에 view 를 표시

Dimension frameSize = this.getSize(); // 프레임 사이즈
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize(); // 모니터 사이즈

this.setLocation((screenSize.width - frameSize.width)/2, (screenSize.height - frameSize.height)/2); // 화면 중앙

this.setLocation((screenSize.width - frameSize.width), (screenSize.height - screenSize.height)); // 화면 우측 상단

이런식으로 운용 가능
