Adding Webcam panel to existing jPanel

Question

I'm using NetBeans and I made basic layout with jPanel in the middle of it. Now I would like to add Webcam panel in this jPanel.

Here's example how to get frames from webcam and display it in new window. It's working fine.

    Webcam webcam = Webcam.getDefault();
    webcam.setViewSize(WebcamResolution.VGA.getSize());

    WebcamPanel panel = new WebcamPanel(webcam);
    panel.setFPSDisplayed(true);
    panel.setDisplayDebugInfo(true);
    panel.setImageSizeDisplayed(true);
    panel.setMirrored(true);

    JFrame window = new JFrame("Test webcam panel");
    window.add(panel);
    window.setResizable(true);
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    window.pack();
    window.setVisible(true);

But when I tried to display it in my existing jPanel it's not working. Webcam screen is not visible. Here's my code:

    Webcam webcam = Webcam.getDefault();
    webcam.setViewSize(WebcamResolution.VGA.getSize());

    WebcamPanel panel = new WebcamPanel(webcam);
    panel.setFPSDisplayed(true);
    panel.setDisplayDebugInfo(true);
    panel.setImageSizeDisplayed(true);
    panel.setMirrored(true);

    jPanel5.add(panel);
    jPanel5.setVisible(true);

I call all of this in my main class constructor. Just after other netbeans componenst are loaded. When I add example it's working good but then my main layout is loaded and webcam screen in another window. I would like to get it in the same window.

I have seen other topics about adding image to jPanel but it's not working with capturing movie from webcam.

Thanks for help.

I changed a little my application and now in the middle of main windows is JTabbedPane and I found a solution to my problem. Instead of making Tabs using NetBeans window designer I made it with code.

I made empty JTabbedPane in Netbeans and then add this to code:

final JPanel jPanelCamera = new JPanel();

jTabbedPane1.addTab("Camera", jPanelCamera);

Webcam webcam = Webcam.getDefault();
webcam.setViewSize(WebcamResolution.VGA.getSize());

WebcamPanel webcamPanel = new WebcamPanel(webcam);
webcamPanel.setFPSDisplayed(true);
webcamPanel.setDisplayDebugInfo(true);
webcamPanel.setImageSizeDisplayed(true);
webcamPanel.setMirrored(true);

jPanelCamera.add(webcamPanel);
jPanelCamera.getParent().revalidate();

System.out.println("Camera OK");

I have no idea why earlier when I made component using NetBeans designer it was't working but now it's working good. I think if someone would add this not to JTabbedPane, but to JPanel should also make this panel with code. Not with Netbeans designer and then it should work.
