javax.swing의 : JEditorPane의 (HTML 페이지)

Question

클래스 브라우저 JEditorPane(new URL("some URL")).

클래스 MainForm 새로운 Browser()를 호출 반환 방법 getBrowserWindow()이 메인 프레임에 표시되지 않습니다. getBrowserWindow() 다른 JEditorPane 객체에 할당합니다.

editor = new Browser().getBrowserWindow(); 
scrollpane = new JScrollPane(editor); 

개체 편집기 .hashCode()가 정확한지, 그래서 올바른 목적을 가지고 의심의 여지가있다.

여전히 메인 프레임의 html 페이지를 볼 수 없습니다..

P. htmlpane 간단한 JEditorPane 대신 텍스트를 사용하여 작성 시도했습니다 및이 하나도 볼 수 없습니다.

P.P.S.

스윙 구성 요소의 인스턴스화로 표시 할 수 없습니다. 그것은 일종의 컨테이너 (JFrame, JPanel ...)에 추가되어야합니다. 재 초기화에 대해서도 유효합니다. 구성 요소를 다시 초기화 한 후에는 이전 버전을 컨테이너에서 제거하고 새 구성 요소를 추가해야합니다.
