just to give you the taste. this is the new impementation of the
simple Toggle I gave you before:
data ToggleLay a = TL Bool deriving (Read,Show)
instance LayoutCombinator ToggleLay a where
pureChooser (TL b) = if b then DoFirst else DoSecond
pureComboHandleMess (TL b) _ _ m
| Just Togg <- fromMessage m = TL (not b)
| otherwise = TL b
data TLay = Togg deriving (Read,Show,Typeable)
instance Message TLay
toggle :: l1 a -> l2 a -> CombinedLayout ToggleLay l1 l2 a
toggle = CombinedLayout (TL True)
Don? Did you see? there are always pure methods in EVERY class!!
