  - PythonQt is not as Pythonic as PyQt in many details (e.g. operator mapping, pickling, translation support, ...) and it is mainly thought for embedding and intercommunication between Qt/Cpp and Python
  - PythonQt allows to communicate in both directions, e.g. calling a Python object from C++ AND calling a C++ method from Python, while PyQt only handles the Python->C++ direction
  - PythonQt offers properties as Python attributes, while PyQt offers them as setter/getter methods (e.g. QWidget.width is a property in PythonQt and a method in PyQt)
- - PythonQt offer QtCore.SIGNAL() and QtCore.SLOT() methods for compability, but no 0/1/3 is prepended
  - PythonQt does not support instanceof checks for Qt classes, except for the exact match and derived Python classes
  - QObject.emit to emit Qt signals from Python is not yet implemented
  - PythonQt does not offer to add new signals to Python/C++ objects
