[PySide] PySide C++ hybrid app

Fri Mar 21 15:14:51 CET 2014

For hybrid Qt C++/Python applications or embedding Python into an existing
Qt application, PythonQt might also be worth a look, also the wrappers are
not as complete as PySide's, it has a nice API for embedding and calling
Python from Qt.
