RadioBox in action

A RadioBox builds on the functionality provided by RadioGroup, See section RadioGroup abstraction, to provide a Smalltalk like radio button group: 


radioBox :: [(Picture,a)] -> Int -> Component (Gauge (a,Int), DisplayHandle)



ls =
 [("Pepperoni",1),
  ("Mushroom",2),
  ("Pineapple",3)]

main =
 wopen ["*name: RBox"] (radioBox ls 1) >>
 return ()

[ToDo: say something about how to disable/enable individual components]
