I can't either, but the sinking/bubling reminds me of how GTK+ handles 
events -- although I think that there the traversal is only 
unidirectional. Every widget in the chain can act on an event, and 
either stop the traversal (handled) or let it bubble further up the 
chain. There is also a filtering mechanism, so widgets can be configured 
to never receive events that they are not interested in.

Good to know that wxWidgets has that limitation. We have considered 
using it, but went for GTK+ instead.
