00044 * A radio button is a tri-state button.  Normally, it is either
00045 * TRUE or FALSE; a third state MAYBE may be set to indicate that no selection
00046 * has been made yet by the user, or that the state is ambiguous.
00047 * When pressed, the radio button sets its state to TRUE and sends a SEL_COMMAND
00048 * to its target, and the message data set to the state of the radio button,
00049 * of the type FXbool.
00050 * A group of radio buttons can be made mutually exclusive by linking them
00051 * to a common data target.  Alternatively, an application can implement a
00052 * common SEL_UPDATED handler to check and uncheck radio buttons as appropriate.
