I tried to use my swing I used jcef browser in the application but encountered problems.
First, I could not add jcef browser as a JPanel component on jFrame. Then I tried to add directly on jframe
[code] getContentPane().add( browser.getUIComponent(),BorderLayout.CENTER); [/ code]

Now when the browser window is loaded inside the JFrame, if I want to switch with other Jpanel, then it cannot be in any way Work
I cannot switch screens after loading the CEF browser. Can anyone point out what I need to do. This is my test jframe.

private JLabel jl1, jl2;
private JButton btn1, btn2;
private CardLayout cardLayout = new CardLayout();

public CardLayoutTst() {
 setTitle("Test med CardLayout");
 setSize(400, 300 );
 cardPanel = new JPanel();
 buttonPanel = new JPanel();
 cardPanel.setLayout(cardLayout);
 jp1 = new JPanel();
 jp2 = new JPanel();
 jl1 = new JLabel("Card 1");
 jl2 = new JLabel("Card 2");
 jp1.add(jl1);
 jp2.add(jl2);
 cardPanel.add(jp1, "1");
 cardPanel.add(browser.getUIComponent(), "2");
 btn1 = new JButton("Show Card 1");
 btn1.addActionListener(new ActionListener() {

 public void actionPerformed(ActionEvent e) {
 cardLayout.show(cardPanel, "1 ");
 }
 });
 btn2 = ne w JButton("Show Card 2");
 btn2.addActionListener(new ActionListener() {

 public void actionPerformed(ActionEvent e) {
 cardLayout.show(cardPanel, " 2");
 }
 });
 buttonPanel.add(btn1);
 buttonPanel.add(btn2);
 add(cardPanel, BorderLayout.NORTH) ;
 add(buttonPanel, BorderLayout.SOUTH);

 addWindowListener(new WindowAdapter() {
 @Override
 public void windowClosing(WindowEvent e) {
 CefApp.getInstance().dispose();
 dispose();
 }
 });

}

public static void main(String[] args) {
 client = CefApp.getInstance().createClient();
 browser = client.createBrowser("http://www.google.com", false, false );

 EventQueue.invokeLater(new Runnable() {

 }

}

}

It’s a bit late, but I ran into the same problem. A friend of mine solved this problem.

You have to create CefSettings, Set windowless_rendering_enabled to false and pass this setting object to the getInstance call:

CefSettings settings = new CefSettings();
settings.windowless_rendering_enabled = false;
 
client = CefApp.getInstance(settings).createClient();
