jzy3d.canvas를 awt.component로 캐스트

Question

jzy3d 캔버스를 java.awt.component로 캐스트해야합니다. JCombobox 및 버튼을 사용하여 프레임에 차트를 표시하고 싶지만 캔버스를 구성 요소에 캐스트하려는 경우 프로그램이 떨어졌다. 답변 해 주셔서 감사합니다. 나는 this을 시도하고 저를 도와주지 않습니다.

것은이 나를 위해 작동합니다. 쉬운 해결책, jzy3d 캔버스를 캔버스에 붙이고 패널에 넣을 때. 당신은 아무것도 할 수 jzy3d이 java.awt.Component``에서 연장하지 않는 경우,하지만가는 아니에요 -

Chart chart = AWTChartComponentFactory.chart(Quality.Advanced, IChartComponentFactory.Toolkit.swing); 
ChartScene scene = chart.getScene(); 
AWTCameraMouseController controller = new AWTCameraMouseController(chart); 
Component canvas = (Component) chart.getCanvas(); 
addMouseListener(controller); 
addMouseMotionListener(controller); 
addMouseWheelListener(controller); 
centerPanel.add(canvas, BorderLayout.CENTER);
