I think HasWidgets is useful because when focus is moved to another
widget, I somehow need to find the widget that just got the focus in
collection of widgets.. So I need to somehow search in widget map.
I need a typeclass because I may have different types of widget
containers and I want to be able to update them uniformly.

Hi Ömer,
I don't think that you need the 'HasWidgets' class, it really doesn't give you a lot. Something like a function 'withFocused' would be a lot more useful:
withFocused :: (Widget -> Widget) -> State Program ()
