将 jzy3d.canvas 转换为 awt.component

Question

我需要将 jzy3d canvas 转换为 java.awt.component，我想使用 JCombobox 和按钮在我的框架中显示图表，但是当我想将 canvas 转换为组件时，程序被删除。谢谢您的回答。我试过了 this 但没有帮助我。

Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException:

        JComboBox functions = new JComboBox(funsToMenu);
        functions.setForeground(Color.gray);

Answer 1

这对我有用。简单的解决方案，当我将 jzy3d canvas 提供给我的 canvas 并将其放入面板时。

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

将 jzy3d.canvas 转换为 awt.component
