Re: [HOpenGL] mouseFunc vs. UserInput

With the mouseFunc callback, it is very easy to recognize if the user has clicked in a point that belongs to a square: [...] I'm trying to do the same using module UserInput.hs. [...]

First of all, I've never imagined that anybody would actually have a deeper look at examples/misc... :-) My suggestion is to extend the type of the callback action, i.e. change type KeyBinder = Key -> KeyEvent -> Maybe (IO ()) -> IO () to type KeyBinder = Key -> KeyEvent -> Maybe (WindowPosition -> IO ()) -> IO () and adapt UserInput.initUserInput in the obvious way. Does this help? Cheers, S.
