Sorry - you can't do this in Python. Both the QListView and the
QDropSite __init__ methods will create separate widgets. The bindings
only create wrappers for existing C++ classes - what you are trying to
do is to create a new C++ class, which you can't do from Python.

If there is no other way of achieving what you want then you will have
to create KFoo in C++ and then create a new Python module using SIP to
wrapp the KFoo class.
