我有演示应用程序，其中我使用 JFXPanel 在 JPanel 中添加 JAVAFX 按钮并将场景添加到 JFXPanel。但是当我删除并再次添加实现我的 JFXPanel 的 JPanel 时，场景被删除或隐藏在 JFXPanel 中，请帮助。
我也尝试过 repain() 和 revalidate() JFXPanel 和 JPanel 但没有任何反应。
这是应用程序的整个代码，请帮助。
public class MainForm extends JFrame {
JButton btnTest;
JButton button;
JLabel lblMessage;
JPanel mainPanel;
JFXPanel jfxPanel;
JPanel panel1;
JPanel panel2;

initialize();

setTitle("Touch Screen Test");

mainPanel = new JPanel();
mainPanel.setLayout(new MigLayout("insets 10 10 10 10"));

panel1.setLayout(new MigLayout("insets 10 10 10 10"));
panel2 = new JPanel();
panel2.setLayout(new MigLayout("insets 10 10 10 10"));
MouseListener listener = new TestButtonListener();
btnTest = new JButton("Test");
btnTest.addMouseListener(listener);
jfxPanel = new JFXPanel();
jfxPanel.setToolTipText("JFX Panel");
jfxPanel.setScene(createScene());
jfxPanel.setPreferredSize(new Dimension(300, 50));
lblMessage = new JLabel("Your message Here.");
lblMessage.setFont(new Font("Arial", Font.PLAIN, 80));
panel1.add(btnTest, "h 50, w 300, push, c, wrap");
panel1.add(jfxPanel, "h 50, w 300, push, c, wrap");
panel1.add(lblMessage, "pushx, c");
button = new JButton("change");
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
if (button.getText().equals("change")) {
mainPanel.remove(panel1);
mainPanel.repaint();
mainPanel.revalidate();
button.setText("changed");
} else {
mainPanel.add(panel1, "push, grow, wrap, cell 0 0");
mainPanel.repaint();
mainPanel.revalidate();
button.setText("change");

mainPanel.add(panel1, "push, grow, wrap, cell 0 0");
