 protected ActionListener actionListener

 protected ItemListener itemListener

 protected ChangeListener changeListenerList

The lists of client listeners.

 protected ActionListener actionListenerList

 protected ItemListener itemListenerList

 public boolean isSelected()

Returns the state of the button. True if the radiobutton is selected, false if it's not.
