Execute code in python pretty printers

[Niko Sams]

Hi,

I'm writing pretty printers for various Qt classes.
For QModelIndex I'd like to show the parent QModelIndex as child. The
parent isn't
saved in the QModelIndex object direclty - instead QModelIndex asks
the model for it's parent.
Basically it returns this->model->parent(this).
QAbstractItemModel::parent is a virtual function implemented
differently in every model.
So to find out the parent the method has to be executed.

Is this possible?
