Qt for Python (PySide/Shiboken)

This is how I've done it so far: if __name__ == "__main__": app = QApplication(sys.argv) engine = QQmlApplicationEngine() #Get Context main = MainWindow() myImageProvider = cam.ImageProvider() engine.rootContext().setContextProperty("backend", main) engine.rootContext().setContextProperty("myImageProvider", myImageProvider) engine.addImageProvider("myImageProvider", myImageProvider) #Load QML File qml_file = Path(__file__).resolve().parent / "qml/main.qml" engine.load(qml_file) if not engine.rootObjects(): sys.exit(-1) sys.exit(app.exec())
