在jPanel上显示动画gif

Question

In the overridden function for my JFrame :

@Override
protected void paintComponent(Graphics g) {

    BufferedImage imagePerson;
    try {
        imagePerson = ImageIO.read(new File("errol.gif"));
    } catch (IOException e) {
        imagePerson = null;
    }

    g.drawImage(imagePerson, i * increment, j * increment - 1, null);
}

How can I change this so the animation on the gif is shown (without using threading). I have spent many hours trying to get this to work but to no avail.

Answer 1

You could use an ImageIcon for this purpose. Have a look here and here . If you need the animation on a JPanel , simply add a JLabel (with the ImageIcon ) to the panel.

Answer 2

Check this example for displaying an animated gif in Swing. you dont have to use any threads:

Icon imgIcon = new ImageIcon(this.getClass().getResource("ajax-loader.gif"));
JLabel label = new JLabel(imgIcon);
label.setBounds(668, 43, 46, 14); // for example, you can use your own values
frame.getContentPane().add(label);
