An implementation of a radio button -- an item that can be selected or
deselected, and which displays its state to the user.
Used with a ButtonGroup object to create a group of buttons
in which only one button at a time can be selected. (Create a ButtonGroup
object and use its add method to include the JRadioButton objects
in the group.)
Note: The ButtonGroup object is a logical grouping -- not a physical grouping. Tocreate a button panel, you should still create aJPanelor similar container-object and add aBorderto it to set it off from surrounding components.
See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for further documentation.
For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JRadioButton key assignments.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.
