Check the Command pattern in Gof books, MFC almost use it in
the same way:
SubWidget in the dialog will catch it firstly, it will
forward it to Parent window(the dialog) if *request is not
for it or no handler defined.

This procedure runs recursively, until one handle it or pass
it to application object. Application will omit unknown
command by default
