Don't associate an action event with the radio button, but, rather, just with the jbutton, then have the listener simply check the value of the radio button. You will probably have to build up a map with the button->radio associations (or make your own "extneds JButton" class where you can store a reference to the radio button directly), however.

Java Syntax (Toggle Plain Text) 
  1. actionPerformed
  2.   if (source == button)
  3.     // if a hashmap
  4.     radio = map.get(button)
  5.     // if a new object
  6.     radio = button.radio
  7.  
  8.   if (radio.isSelected())

I assume you know how to create a map? I assume you know how to use the "extends" keyword.

Why the map? Why not just test the button to see if it's checked?
