I'm sorry if I sounded harsh. It was not my intention.

Those notify jumps between child and parent widgets.

If you're on the child you'll receive GDK_NOTIFY_ANCESTOR and in the
parent  GDK_NOTIFY_INFERIOR. 

So you'll will get GDK_NOTIFY_INFERIOR when the
pointer moves on child windows, and GDK_NOTIFY_ANCESTOR
when it moves on the parent.

I've seen it in code, mostly to avoid to track notifications on composite widgets' child windows, to track 
them in the parent's event box.

if ((event_widget == widget) &&
      (event->detail != GDK_NOTIFY_INFERIOR))
