Converting c++ into Python

Pythonic person

Hello all, and am super sorry to post such a thing but am super noob with C++ language and I was struggling with the integration external application within my pyqt5 app but am stuck with many problem and they are addressed here in this link:
unity thread
GitHub Code of C++ working example

So can any body help me with converting that code from git into a working python. and again am super sorry for my dumb question.

I don't know what this unity thing is so I don't know what this is supposed to do. I converted over most of it but I left out the windows OS specific stuff because I didn't feel like messing with it at the moment (I don't know much c++ either). It's pyside6 instead of pyqt5 but hopefully this will be enough to get you started.

class UnityWindow(QWidget):
    def __init__(self, unityExePath, parent=None):
        super().__init__(parent)
        self._m_unityHandle = 0
        self._m_bIsValid = False
        self._m_pUnityProcess = None
        self._m_unityExecutablePath = unityExePath
        app.applicationStateChanged.connect(self.applicationStateChanged)

    def enumChildWindows(self, handle):
        # if windows do stuff
        pass

    def isValid(self):
        return self._m_bIsValid

    def applicationStateChanged(self, state):
        # if windows do stuff
        pass

    def resizeEvent(self, ev):
        super().resizeEvent(ev)
        # if windows do stuff

    def sEnumChildWindows(self, handle, params):

    item = QGraphicsTextItem("Test Item")

    splitter.addWidget(view)

    mainWindow.setCentralWidget(splitter)

    mainWindow.show()

    sys.exit(app.exec())

Hello @Pythonic-person
In the Qt for Python repository, we have an internal tool that's for sure not ready for production, but it help us to transform some C++ code to Python:

https://code.qt.io/cgit/pyside/pyside-setup.git/tree/tools/qtcpp2py.py

I hope it helps with future projects :)
