mkLeafWidget :: forall v a. ((a -> Effect Unit) -> v) -> Widget v a

Construct a widget with just props

mkNodeWidget :: forall v a. ((a -> Effect Unit) -> v -> v) -> Widget v a -> Widget v a

Construct a widget, by wrapping an existing widget in a view event

mkNodeWidget' :: forall v a. ((a -> Effect Unit) -> v -> v) -> Free (WidgetStep v) a -> Free (WidgetStep v) a

class (Monad m, Monoid v, ShiftMap (Widget v) m, LiftWidget v m, MultiAlternative m) <= IsWidget v m 

A Nice way to bring into scope all needed functionality which we need to write widgets
