② JAVA(자바) 프로젝트-1 최소화시 시스템트레이에 보내기(숨기기) 및 화면내단축키 설정 == Send (hide) to the system tray when minimized and set onscreen shortcuts

 

인스턴스를 생성, LookAndFeel을 세팅, 시스템 트레이 추가,  시스템트레이 아이콘생성,  popupMenu에 추가, 화면내 단축키 설정 ,  트레이시 open과 exit때 ,최대화일때, 원래크기일때 등이 구현되었습니다.

자세한 내용은 코드 중간중간 System.out.println 으로 설명이 되어있습니다.

코드입니다.
