Using Qt Creator's QML Debugger for a PySide6 QML Application ************************************************************* Besides the C++ debugger, *Qt Creator* provides a `QML debugger`_ which lets you inspect JavaScript code. It works by connecting to a socket server run by the ``QmlEngine`` instance. The port is passed on the command line. To enable it, add the below code to your QML application: .. code-block:: python from argparse import ArgumentParser, RawTextHelpFormatter ... if __name__ == "__main__": argument_parser = ArgumentParser(...) argument_parser.add_argument("-qmljsdebugger", action="store", help="Enable QML debugging") options = argument_parser.parse_args() if options.qmljsdebugger: QQmlDebuggingEnabler.enableDebugging(True) app = QApplication(sys.argv) For instructions on how to use the QML debugger, see `Debugging a Qt Quick Example Application`_. .. note:: The code should be removed or disabled when shipping the application as it poses a security risk. .. _`QML debugger`: https://doc.qt.io/qtcreator/creator-debugging-qml.html .. _`Debugging a Qt Quick Example Application`: https://doc.qt.io/qtcreator/creator-qml-debugging-example.html
