Help! Using a custom renderer to display an image

Question

I have a JTable where I want to set the renderer of one column to a custom renderer. And I want this renderer to show either a play button image, or a stop button image, depending on the status, which is a Boolean value. However, the image won't show up when I run the application. Here's the code from the renderer...
public class StatusRenderer extends DefaultTableCellRenderer {
private ImageIcon playIcon = new ImageIcon("C:/play.jpg");
private ImageIcon stopIcon = new ImageIcon("C:/stop.jpg");
public StatusRenderer() {
setHorizontalAlignment(JLabel.CENTER);
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int col) {
Boolean b = (Boolean) value;
setIcon(b.booleanValue() ? playIcon : stopIcon);
return this;
The application runs, but no icon shows up in the table cell. I'd really appreciate any help on this. Thanks.

look at http://www2.gol.com/users/tame/swing/examples/JTableExamples1.html
for some great table examples (they may need minor mods to work on 1.3/1.4)
Basically I think you need something more like:
public class StatusRenderer extends JLabel
  implements DefaultTableCellRenderer
    public StatusRenderer() {
        super();
        setHorizontalAlignment(JLabel.CENTER);
    public Component getTableCellRendererComponent(JTable table,
                                       Object value, boolean sSelected,
                                       boolean hasFocus, int row,
                                       int col)
        Boolean b = (Boolean) value;
        setIcon(b.booleanValue() ? playIcon : stopIcon);
        return this;
}Don't forget to add the renderer to the column you want it in !
