Use a CheckboxGroup bean to provide a set of mutually exclusive choices that appear as radio buttons. Each choice in the group is a Checkbox bean that you associate with the CheckboxGroup bean.
Use JRadioButton beans with a Swing ButtonGroup, rather than Checkbox beans with a CheckboxGroup, if you want to use them in a Swing container. Although Swing and AWT beans can be mixed, it is inadvisable.
