[gtkada] GDK 2.2.0 and Event Handling

[Manuel Op de Coul]

I'm not finished porting yet since my application is quite big,
so maybe I will have an insight about this when I see mine running.

All I can say at the moment is that although your application ran
fine in the past, it doesn't mean there can't problems with it.
Often I had problems which only showed on either Windows or Linux.
