Bonjour List,

Thanks to Jeremy O'Donoghue's blog about events, I copied and modified
two functions; but without really understanding what's going on :

windowOnIconize :: Window a -> IO () -> IO ()
windowOnIconize win eventHandler
  = windowOnEvent win [wxEVT_ICONIZE] eventHandler (\evt -> eventHandler)

windowGetOnIconize :: Window a -> IO (IO ())
windowGetOnIconize win
  = unsafeWindowGetHandlerState win wxEVT_ICONIZE skipCurrentEvent

and then somewhere I added:

windowOnIconize win $ putStrLn "Iconize!!!!"

But I've no idea how/where to use the windowGetOnIconize function...

Now when I try the program, I get the Iconize!!!! message when I
(de-)iconize the window, which is great, but I segfault when I close
the window.

David.
