class Fox::FXRadioButton

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.

Events

The following messages are sent by FXRadioButton to its target:

SEL_COMMAND

SEL_LEFTBUTTONPRESS

sent when the left mouse button goes down; the message data is an FXEvent instance.

SEL_LEFTBUTTONRELEASE
