[pygtk] Add global event handler

[Fredrik Corneliusson]

Hi Folks,
I want to add a function similar to MS Windows Alt keycodes
("http://en.wikipedia.org/wiki/Windows_Alt_keycodes") to be able to
enter special characters in any widget.

Now I've added event handler for the main window but my application
uses multiple windows (search/replace etc.) and I would prefer to not
explicitly add event handlers for every window.

What would be the best way (and is is possible in pygtk) to do this so
all widgets support this?

BTW, I'm aware of the default GTK way ("CTRL+SHIFT+uNNNN") of entering
characters by their hexadecimal value but that is not an option for
this application as it needs to integrate well in win32.

Regards,
Fredrik
