Now i understand better the situation. I've been convinced that the father
view receive all the hooks anyway, i've think of it as a bug.
I believe BView::SetEventMask() [1] can help you with that, though.

So if i understood correctly i can't simply intercept them in
MyCustomView::MessageReceived() just because they are dispatched directly
by the looper (BWindow) to the final handler. I'll see what to do, i
already have a filter in the main window. I'll go this way, very thanks for
clarification.
