이런식으로 코드를 짜서
맨위의 variable 클래스에다가 전체적으로 사용하는 변수들 선언하였고
jp1에서 테이블 생성하고 jpn11은 jtp위에 올라간 패널입니다.
jpn11의 버튼을 누르면 jp1의 테이블이 갱신되게끔
showtable을 만들고 각 버튼 이벤트에 들어가게
model.setRowCount(0); showtable();
를 넣었습니다. 그런데 showtable이 jpn11에서는 갱신 되지 않고
jp1에 showtable을 생성하고 재시작하면 갱신 화면이 보이긴 합니다.
쿼리는 잘못 되지 않은거 같은데 어떤 부분이 이상이 있는건지 화면이 갱신이 안되서.... 감을 못잡겠어서 코드와 함께 질문드렸습니다.
반복적인 질문에 죄송합니다. 약 3일간 이 파트만 찾긴했는데... 제 구글링에 한계인거 같아서 질문 드렸습니다.
