Main类的JFrame中另一个类的JPanel大小问题

Question

我正在尝试将JavaFx浏览器组件添加到我的swing应用程序中。 我需要在选项卡式窗格中加载浏览器，并在运行时动态将URL设置为这些浏览器。 因此，我有以下代码将浏览器呈现到JFrame中，但是输出不会以框架的大小显示。 浏览器组件将在选项卡式窗格中以小尺寸显示，而不是在整个框架中显示。 请根据以下代码指导我在哪里进行更正：

    public class BrowserScene extends JPanel {

private static final long serialVersionUID = 5114913691608034106L;
private JFXPanel jfxPanel;
private WebEngine engine;

private JPanel panel = new JPanel(new BorderLayout());
private JLabel lblStatus = new JLabel();

private JButton btnGo = new JButton("Go");
private JTextField txtURL = new JTextField();
private JProgressBar progressBar = new JProgressBar();

private void initComponents() {
    jfxPanel = new JFXPanel();
    jfxPanel.setSize(new Dimension(1200, 1000));

    createScene();

    ActionListener al = new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            loadURL(txtURL.getText());
        }
    };

    btnGo.addActionListener(al);
    txtURL.addActionListener(al);

    progressBar.setPreferredSize(new Dimension(150, 18));
    progressBar.setStringPainted(true);

    JPanel topBar = new JPanel(new BorderLayout(5, 0));
    topBar.setBorder(BorderFactory.createEmptyBorder(3, 5, 3, 5));
    topBar.add(txtURL, BorderLayout.CENTER);
    topBar.add(btnGo, BorderLayout.EAST);

    JPanel statusBar = new JPanel(new BorderLayout(5, 0));
    statusBar.setBorder(BorderFactory.createEmptyBorder(3, 5, 3, 5));
    statusBar.add(lblStatus, BorderLayout.CENTER);
    statusBar.add(progressBar, BorderLayout.EAST);

    panel.add(topBar, BorderLayout.NORTH);
    panel.add(jfxPanel, BorderLayout.CENTER);
    panel.add(statusBar, BorderLayout.SOUTH);

    add(panel);
