Custom error page for QtWebEngine

Is there any way to set a custom error page for QtWebEngine? Or maybe there is some way to get the error status code when QWebEnginePage emits loadFinished(false)?

Good question! Does https://stackoverflow.com/questions/40309105/capture-server-response-with-qwebengineview give you any help/leads for getting at the status code? It's useful reading anyway.

EDIT Hmm, https://stackoverflow.com/questions/51656117/how-to-get-http-status-codes-from-qt-qwebengineview talks about trying QWebEngineUrlRequestInterceptor but I think no luck. Again you should read because it looks like others are having same problem as you getting at the HTTP code. And http://code.qt.io/cgit/qt/qtwebengine.git/tree/src/webenginewidgets/api/qwebenginepage.cpp#n367 might be useful.

@JonB Thanks for your reply, but I have no idea how to use your latest link to solve my problem.

If by "your latest link" you mean http://code.qt.io/cgit/qt/qtwebengine.git/tree/src/webenginewidgets/api/qwebenginepage.cpp#n367, I am suggesting you examine that source code to understand what Qt is actually doing in loadFinished(false), e.g. at first glance it does not seem to be passing errorCode/errorDescription on to the emitted signal. I know nothing, but it does test settings->testAttribute(QWebEngineSettings::ErrorPageEnabled), so maybe that gives a clue that there is some access to an error page?
