Background image in extended awt.Button doesn't show.

Question

Hi all
I have an applet that has only an awt.Button visible on the page. Because of layout requirements I need to style that button with a background image. I have extended the java.awt.Button like this:
     class ImageButton extends Button {
          public void paint(Graphics g) {
               super.paint(g);
               g.drawImage(getImage(getDocumentBase(), "../img/loadSertificate.jpg"),
                         0, 0, null);
     }and use the extended:
     public void init() {
          mSignButton = new ImageButton();
          mSignButton.setLocation(0, 0);
          Dimension appletSize = this.getSize();
          mSignButton.setSize(appletSize);
          mSignButton.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    signSelectedFile();
          this.setLayout(null);
          this.add(mSignButton);
     }Now everiting is ok but when the applet is loaded the background image doesn't show and only a plain gray button is visible. The interesting part is that the image does show after I click somewhere in the browser's window and later on it's always visible as expected.
Below is part from the log from the java console:
basic: Applet started
basic: Told clients applet is started

Answer 1

xmm sry but this was a forgotten repaint() :
          public void paint(Graphics g) {
               // call super's paint method
               super.paint(g);
               g.drawImage(getImage(getDocumentBase(), APPLET_BUTTON_IMAGE_URL),
                         0, 0, null);
               repaint();
          }Now it seems to work fine.
