143 - PythonQt is not as Pythonic as PyQt in many details (e.g. operator mapping, pickling, translation support, ...) and it is maily thought for embedding and intercommunication between Qt/Cpp and Python
143 - 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
144 144 - 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
145 145 - 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)
146 - PythonQt does not (yet?) offer QtCore.SIGNAL() and QtCore.SLOT() methods, connect and disconnect just take strings for signals and slots
147 - QObject.emit to emit Qt signals from Python is not yet possible
146 - PythonQt offer QtCore.SIGNAL() and QtCore.SLOT() methods for compability, but no 0/1/3 is prepended
147 - PythonQt does not support instanceof checks for Qt classes, except for the exact match and derived Python classes
148 - QObject.emit to emit Qt signals from Python is not yet implemented
149 - PythonQt does not offer to add new signals to Python/C++ objects
148 150 - Ownership of objects is a bit different in PythonQt, currently Python classes derived from a C++ class need to be manually references in PythonQt to not get deleted too early (this will be fixed)
149 151 - Probably there are lots of details that differ, I do not know PyQt that well to list them all.
