jpanel implementing button behavior

I want to create a radio button that has more components than the default JRadioButton. I'm wondering what the best method is, should I subclass JRadioButton adding my extra components or is it better to subclass JPanel and add the behavior of a radio button as shown below.

---------JPanel---------------
- Titel (Label)              -
- RadioButton (JRadioButton) -
- Description (label)        -
------------------------------

The whole panel should be focusable and should provide feedback when clicked or has focus. Thanks for your help.

None of the above.

  • Don't extend components unless you genuinely need to extend functionality, especially not merely for decoration.

  • Don't confuse the containment hierarchy with the class hierarchy.

  • Don't defeat the existing focus subsystem unless you plan to provide your own.

  • If you want to alter the appearance of the panel when the radio button's focus changes, do so in a focus listener attached to the button. The background color of an opaque panel is a bound property, so setBackground() should be sufficient.
