Re: Radio button and JButton problem

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.

Re: Radio button and JButton problem

Java Syntax (Toggle Plain Text)
actionPerformed
  if (source == button)
    // if a hashmap
    radio = map.get(button)
    // if a new object
    radio = button.radio
 
  if (radio.isSelected())
actionPerformed
  if (source == button)
    // if a hashmap
    radio = map.get(button)
    // if a new object
    radio = button.radio

  if (radio.isSelected())

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

Re: Radio button and JButton problem

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