jFileChooser 스윙 창을 사용해야하는 프로젝트에서 작업하고 있습니다. "취소"또는 "열기"를 클릭하면 창이 닫히지 않습니다. 여기 StackOverflow에서 여러 개의 게시물을보고 JFileChooser tutorial 및 documentation을 보면이 반복되는 문제의 원인을 놓치고 있습니다.JFileChooser가 올바르게 닫히지 않습니다.
NetBeans와 함께 스윙 편집기를 사용하고 있습니다. 나는 또한 이클립스에서이 프로그램을 테스트 해 본 결과 동일한 결과를 얻었다.
새로운 업데이트 :
여기에 코드의 SSCCE 버전에서 내 시도는, 양해 해 주셔서 감사합니다 :

해결책 : 넣어 넷빈즈 파일에서 여분의 물건을 삭제 한 후, (살) 가지는 JDialog, JFrame, 및 JMenuItem를, 그것은이에 가정되는 방식으로 작동합니다.
