JDialog 위에 Joptionpane이 모달이 아닌 이유

Question

JDialog의 잘못된 사용자 입력에 의해 호출되는 오류 메시지로 JOptionpane을 사용했습니다.

모덜 유형 : 응용 모달
modalExclusionType : JOptionPane에이 JDialog를 여전히 작동 나타날 때 APPLICATION_EXCLUDE

는 문제입니다. 다음 JOptionPane에

JOptionPane.showMessageDialog(JDialog's name, "you must fill in all required fields", "Error!", 0); 

를 호출하는 코드는이 문제를 해결하기 위해 어떤 방법이 무엇입니까? 여기

는 최소한의 예제 프로그램을 것입니다

Answer 1

문제는 여기에 있습니다 :

modalExclusionType : 윈도우 API 당 APPLICATION_EXCLUDE

:

지정 이 윈도우의 모달 제외 유형 모달이 제외 된 모달은 일부 모달 대화 상자에 의해 차단되지 않습니다. 가능한 모달 제외 유형은 Dialog.ModalExclusionType을 참조하십시오.

이 값을 설정하지 않으면 JOptionPane이 대화 상자 창을 제대로 차단합니다.
