사용자가 외부에서 클릭 할 때 모달 JDialog를 깜박이는 방법

Question

대화 상자 바깥 쪽을 클릭했을 때 발생하는 이벤트를 잡는 방법 대신 깜박이는 코드가 중요하지 않습니다.

Windows에서 대화 상자 바깥을 클릭하려고하면 소리가 'ding'으로 들리고이 이벤트의 악곡을 뛰어 넘을 수 있는지 궁금합니다. 이것이 가능한가?

감사합니다.

대화 모달을 확인하고 그것을 부모를 제공합니다. E.G. JDialog(Frame,String,boolean) 생성자를 사용합니다.

JDialog blockingDialog = new JDialog(mainFrame, "Blocking Dialog", true);
