gtk_grab_add() only redirects existing events, it doesn't
change the current event masks of widgets - so if they aren't
asking for motion events, then you won't get them

If you want to actually get all events, then you want use
gdk_pointer_grab() - something like:


 gdk_pointer_grab (eventbox->window, FALSE, GDK_MOTION | GDK_BUTTON_RELEASE,
                   NULL, NULL, time);
