Is it possible to show a JLabel over another JLabel?

Answer 1

Solution 1:
JLabel is a container, So you can add any component on top of JLabel but normally it will not display but if you set any layout then you can see the added component.
    public static void solution1() {
     JFrame frame = new JFrame();
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     JLabel bigImg = new JLabel(new ImageIcon("F:\\tmp\\bigImg.jpg"));
     JLabel logo = new JLabel(new ImageIcon("F:\\tmp\\logo.gif"));
     frame.getContentPane().add(bigImg, BorderLayout.CENTER);
     bigImg.setLayout(new FlowLayout(FlowLayout.RIGHT, 0, 0));
     bigImg.add(logo);
     frame.pack();
     frame.setVisible(true);
    }Disadvantage : if the label size was changed depends on the layout the position of the logo goes outside of the big image(in the above example maximize the window to see that issue).
Solution 2:
draw the logo image on top of the big image.
    public static void solution2() {
     JFrame frame = new JFrame();
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     ImageIcon bigImg = new ImageIcon("F:\\tmp\\bigImg.jpg");
     ImageIcon logo = new ImageIcon("F:\\tmp\\logo.gif");
     int w = bigImg.getIconWidth();
     int h = bigImg.getIconHeight();
     BufferedImage bf = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
     Graphics2D g2d = bf.createGraphics();
     g2d.drawImage(bigImg.getImage(), 0, 0, frame);
     g2d.drawImage(logo.getImage(), 0, 0, frame);
     JLabel label = new JLabel(new ImageIcon(bf));
     frame.getContentPane().add(label, BorderLayout.CENTER);
     frame.pack();
     frame.setVisible(true);
    }Advantage : whenever the label component size changed the logo must be on the big image of the same position because the logo was painted on top of the big image.
