Hi,

When creating a subclass of QWebEnginePage:

class WebEnginePage(QWebEnginePage):
    def javaScriptPrompt(self, url, msg, param):
        return super().javaScriptPrompt(url, msg, param)

I got this error:

TypeError: WebEnginePage.javaScriptPrompt() takes 4 positional arguments but 5 were given

Which does not conform to the method specification in the pyi file:

def javaScriptPrompt(self, securityOrigin: Union[PySide6.QtCore.QUrl, str], msg: str, defaultValue: str) -> Tuple[bool, str]: ...

virtual protected bool 
    QWebEnginePage::javaScriptPrompt(const QUrl &securityOrigin,
                                     const QString &msg, 
                                     const QString &defaultValue, 
                                     QString *result)
