PyQt4 has API 1 (default for Python 2), and API 2 (default for Python 3). But you can manually set the API in Python 2 to API 2, using something such as:

import sip
for item in ('QDate', 'QDateTime', 'QString', 'QTextStream', 'QTime'
             'QUrl', 'QVariant'):
    sip.setapi(item, 2)

Why is API 2 better?
To put it short, API 2 converts Qt types to native Python types. It makes code seamless. For example, you wouldn't need to use QString anymore, just a regular python str. This of course applies to other types like lists, dicts, etc.

Take a look at this PSEP which better describes the differences.

Considering the nature of this request, it's probably best to do this for all KDE4 Python bindings as well, to keep things consistent.

WARNING: This has the potential to break many widgets and programs which depend on PyKDE4! But this is really for the ultimate benefit of everyone however. :) Porting code form the old to the new style shouldn't be too hard either.
