This is not a hack, it is just a feature provided. This is the way you can add your own custom components to JFileChooser. You don't actually need the JPanel, I just added it, you can directly add JLabel to it. But in order to have a layout of the components we added i added JPanel. Good to know if we can add components in a certain layout to the JFileChooser without JPanel and without disturbing the layout of the JFileChooser's by-birth components.
