- public class JRadioButton
- extends JToggleButton
The JRadioButton component provides a visually selectable
button with mutually exclusive behaviour within a ButtonGroup.
A series of radio buttons can be used to provide options to the user,
where the user can only select one of the available options. The state
of the button is provided by the superclass, JToggleButton.
JRadioButton adds the additional behaviour, that if two
or more radio buttons are grouped together, the selection of one implies
the deselection of the other buttons within the group.
Buttons are grouped by adding each instance to a ButtonGroup.
The existence of such a grouping is not reflected visually, so other means
should be used to denote this. For instance, the grouped buttons can be placed
within the same panel, possibly with an appropriate border to denote
the connection between the components.
