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