Scaling JFrame content

I got a JLayeredPane with a JLabel containing an Image in it. This looks like this:

JLayeredPane panel = new JLayeredPane();
JLabel label1 = new JLabel();
label1.setIcon(new ImageIcon(image));
label1.setBounds(0, 0, 1300, 900);
panel.add(label1, 0);
frame.add(panel);
frame.setSize(1320,900);
frame.setVisible(true);

And some other images in the JLayeredPane.

It all displays fine. But when I scale the frame in windows the images dont scale. (The images stay the same size and the window just gets bigger with greyspace.) Now my question: What can I do so the images are always filling the frame no matter how i scale it?

All you really need is JComponent with an Image, and override paintComponent like this:

public class FillImage extends JComponent {
    final Image image;

    public FillImage(final Image image) {
        this.image = image;
    }

    @Override
    public paintComponent(Graphics g) {
       // Additionally, you may set extra hints for better scaling

       // Draw image stretched to fill entire component
       g.drawImage(image, 0, 0, getWidth(), getHeight(), null);
    }
}

Then, make sure the FillImage component is added to a container with a layout that makes it fill all the space available (like BorderLayout in CENTER).

Not sure why you are using a JLayeredPane for this.

Maybe you can use Darryl's Stretch Icon class.
