나는 약간의 실수 일 것이라고 확신하지만 찾을 수 없습니다. 내 서버 GUI를 시작하면 그 구성 요소가 나타나지 않습니다. 내가 가진 모든 것은 정확한 크기의 빈 페이지입니다.스윙 : GUI에 내 구성 요소가 표시되지 않습니다.

이 클래스는 여기에 호출되는 : 코드 많이입니다

1) 좀 더 나은 도움을 받으려면 [SSCCE] (http://sscce.org/)를 게시하십시오 (추가 사용자 정의 클래스를 나타내는 코드 300 개가 아닌). 2) 이것은 EDT를 막는 효과와 같이 의심스럽게 들립니다. EDT (Event Dispatch Thread)를 차단하지 마십시오. GUI가 그럴 때 멈출 것입니다. 를 호출하는 대신'Thread.sleep (n)'은 작업 반복을위한 Swing 타이머를 구현하거나 장시간 실행되는 작업을위한 SwingWorker를 구현합니다. 자세한 내용은 [동시성 (Concurrency in Swing)] (http://docs.oracle.com/javase/tutorial/uiswing/concurrency/)을 참조하십시오. –
