In C++, inheriting from QObject more than once is explicitly forbidden. 
While it *might* be possible to make this work in PySide, I wouldn't 
count on it, nor would I particularly recommend it.

What is the purpose of inheriting from both? You may be better off 
having one as an internal object of the other, similar to how there is 
an internal QLineEdit of QComboBox.
