QWebEnginePage::certificateError Qt5

franco.amato

I have this Qt6 code that I have to adapt to Qt5

connect(webPage, &QWebEnginePage::certificateError, this, &Home::onCertificateError);

And the slot:

void Home::onCertificateError(QWebEngineCertificateError error)
{
    auto mutableError = const_cast<QWebEngineCertificateError&>(error);
#if QT_VERSION >= QT_VERSION_CHECK(6,0,0)   
    mutableError.acceptCertificate();
#else
    mutableError.ignoreCertificateError();
#endif 
}

Unfortunately I cannot find a Qt5 alternative to the signal

QWebEnginePage::certificateError

Any suggestion on how I can solve my problem?

It's QWebEnginePage now: https://doc.qt.io/qt-6/qwebenginepage.html#certificateError

According to https://doc.qt.io/qt-5/qwebenginepage.html#certificateError, In Qt5 certificateError is not a signal but a virtual protected function, so instead of connecting a slot like in Qt6, you'll need to subclass QWebEnginePage and reimplement the function.

@Bonnie @franco-amato Oh, it looks like I misunderstood the question, forget my post :-)

Unfortunately I cannot subclass the QWebEnginePage. Do you know any other workaround that can temporarily fix?

@franco-amato Nope, that seems to be the only way in Qt5.
If you are using QWebEngineView, it is possible to use subclassed QWebEnginePage.
Just create an instance and make it replace the original one by calling QWebEngineView::setPage.

I didn't get your suggestion. Ccould you help with a small example code please?
