[PyQt] Trouble reading a model index from an "untouched" combo box

[Demetrius Cassidy]

I don't think you need to use the view pointer at all - it's returning 
QAbstractItemView *, which I would assume it would need to be casted to 
the proper class in C++. If that's so, by design the Abstract class will 
return an invalid index. Try to use self.comboBox.currentIndex() instead 
- it returns -1 if theres no selected index (which there won't be when 
you first set the model until you manually or programatically select one)
