The QApplication can be accessed via the global pointer "qApp".

If you want to access public members in your "main widget" (whatever class 
it's been derived from), you'd have to keep a global pointer for it thoughout 
your project... how should Qt know about the role of any of your widgets? You 
could even have several QMainWindow's.

Anyway, as far as I understand your question, it's still more C++ than Qt 
related.
