Class Fox::FXRadioButton
In: rdoc-sources/FXRadioButton.rb
Parent: FXLabel

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 message to its target, with the message data set to the state of the radio button. A group of radio buttons can be made mutually exclusive by linking them to a common data target (i.e. an instance of FXDataTarget). Alternatively, an application can implement a common SEL_UPDATE handler to check and uncheck radio buttons as appropriate.

SEL_COMMAND:sent when the radio button is pressed.
