Yeah, but this gives you a pointer to the currently _active_ QWidget (= the 
one that has input focus), which is not necessarily the same as the "main 
widget". And you'd still need to use a cast to your specific sub-class to 
access custom members in it... this will only be valid if your application 
has just ONE (and only ONE) top-level widget!!
