Prefuse jframe 생성시 이미지

Question

Prefuse로 두 이미지와 선을 그려야합니다. 그러나 jframe을 만들 때 내 이미지가로드되지 않습니다. 라벨을 클릭하면 클릭 한 라벨 이미지가 나타납니다. 하지만 jframe을 만들 때 그 이미지가 나타나기를 바랍니다. 내가 어떻게 해. 여기

즉 '아무튼 경우, 즉, JFrame의 생성 후

// create a new window to hold the visualization 
JFrame frame = new JFrame("prefuse example"); 
// ensure application exits when window is closed 
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
frame.add(d); 
frame.pack();   // layout components in window 
frame.setVisible(true); // show the window 


vis.run("draw"); 
vis.run("layout"); 

을 그리기 작업을 실행 해보십시오 또는 t 작업, 호출 frame.repaint(). 당신은 어떻게 든 시각화의 드로잉을 강요 할 필요가 있습니다.
