Question

I have a couple of JButtons that don't visually change to the pressed state when I click them. They're both enabled. Anyone know why?

Anyone else?
Here's the code for my button if it helps any:
public class ImageButton extends JButton {
   private ImageIcon icon;
   public ImageButton(String path, Color bgColor) {
      icon = new ImageIcon(path);
      this.setSize(icon.getIconWidth(), icon.getIconHeight());
      //this.setBorder(BorderFactory.createLineBorder(Color.LIGHT_GRAY));
      this.setBackground(bgColor);
      this.setIcon(icon);
      this.setHorizontalAlignment(SwingConstants.CENTER);
}
