It connects to key, mouse button, mouse motion, resize and close  
events since that's all SOE uses.

Obviously, it wouldn't be too hard to write a function that connects  
to all possible events of a window and displays the result. One could  
define such a function outside of Gtk2Hs. The attached file is a  
modification of the hello world demo. I realised that Event is not  
actually in class Show, so I added that in the darcs repository.  
Thus, you have to go bleeding edge to actually run the program :-(
