Draw image to JPane in NetBeans

Question

I am developing a GUI in NetBeans that is for changing the settings.
one setting is a username and password.
once the user has inputed a username and password it needs to show a GIF image which is a loading kinda circle thing that goes around i don't have a problem with knowing when to show the image and start the request it is just the showing the image bit at the moment i have this code:
public ConfigGUI() {
     initComponents();
     center();
     System.out.println("Loading image");
     Graphics loginGraphics = loginPane.getGraphics();
     LoadImageApp image = new LoadImageApp("resources/strawberry.jpg");
     loginGraphics.drawImage(image.img, 1, 1, null);
     loginPane.repaint();
     loginPane.setVisible(true);
     System.out.println("Image loaded");
    /* image class */
    public class LoadImageApp extends Component {
     BufferedImage img;
     //@Override
     public void paint(Graphics g) {
         g.drawImage(img, 0, 0, null);
     public LoadImageApp(String filename) {
         try {
          img = ImageIO.read(new File(filename));
         } catch (IOException e) {
          System.out.println("Failed to load image");
     //@Override
     public Dimension getPreferredSize() {
         if (img == null) {
          return new Dimension(100, 100);
         } else {
          return new Dimension(img.getWidth(null), img.getHeight(null));
    }but it doesn't work.
am i using the right kind of components or do i need to use something other than a JPane?
and what code should i be using to output the image?

Answer 1

If you're using Swing here, I wonder if you should draw in either a JPanel or a JComponent, but not in a Component. Also, if you do use either JPanel or JComponent, then you should override the paintComponent method not paint. If this suggestion doesn't help, then consider posting an [SSCCE,|http://sscce.org] but if you do so, I recommend that it be very very simple and not be NetBeans-generated.
Good luck.
edit: on second look your code looks a little odd. Why are you loading an image into a component but not viewing it in that component, but instead pulling out the image variable and using it elsewhere? It looks a bit strange but perhaps you have a good reason for doing it this way? Have you read the Sun graphics tutorials yet? if not, they are quite well written.
