Class JButtonGroup<T>

java.lang.Object
  javax.swing.ButtonGroup
      org.tbee.swing.JButtonGroup<T>

All Implemented Interfaces:

java.io.Serializable

public class JButtonGroup<T>
extends javax.swing.ButtonGroup

Extends javax.swing.ButtonGroup to provide methods that allow working with button references instead of button models. By using bindValue(button, value) or the associated add(button, value) it is possible to relate a value to a button. By using setValue(), getValue() and the value property change event, the buttongroup can be bound to a bean property.
