The first question is: why do you need to catch MouseDown events inside 
CDiceBoard class?

Anyway, events are intended to the final user of an object. If you need to 
intercept them inside the implementation of the object class, you have to use 
Observers. 

An observer is an object that can intercept any event on any object: look the 
documentation in the wiki about the Observer class in the gb component.
