size issue of JPanel from another class inside the JFrame of Main class

Question

I'm trying to add JavaFx Browser components into my swing application. I need to load browsers in tabbed panes and set the url's to those browsers dynamically during runtime. So i have the following code which renders the browser into the JFrame, but the output does not comes out in the size of the frame. The browser component gets displayed in small size inside the tabbed pane rather than in the full frame size. Please guide me where to correct from the following code:

    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);     
}

private void createScene() {
