I don't remember exactly... the popup is actually a private container for the 
view. It is certainly possible to walk to it from view(), but that isn't the 
problem.
IIRC the QComboBox::showPopup virtual is actually 200 loc doing all kind of 
fancy sizing calculations with some private methods, that won't work on our 
offscreen widgets.

So the bottom line is, it probably is possible to do it, at the expense of 
reimplementing the functionality of those 200 loc.
