oh my god! I can't believe i was so blind! Thanks a lot to both! I switched the connection back to QWebEngineView. I don't even remember why I thought that sending the signal from QWebEnginePage was a good idea, since i have to delete the pointer not to let it hanging. Now it seems to work, but pix comes out blank. Perhaps loadfinished is too quick, and triggers before javascript has finished generating the document? Is there a slower signal? Or perhaps a way to give js a tad more of time to load before calling render? Before using signals and slots I tried to wait it with a loop, but it seems the loop blocks js.

https://stackoverflow.com/questions/58875159/how-to-ignore-ssl-certificate-errors-with-qwebengineview link helped me to resolve the issue. Now HTTPS page load after ignoring ssl warning is fine. Thanks for ideas :)

Ok so I managed to import the html by modeling my code similar to the example with: QString code = QStringLiteral("qt.jQuery('#first_page').load('html/first_page.html');"); //you can even nest it with: QString code = QStringLiteral( "qt.jQuery('#first_page').load('html/first_page.html', ()=>{" "qt.jQuery('#border_content').load('html/border_content.html', ()=>{" //some other html "qt.jQuery('#last_page').load('html/last_page.html');" "});" "});" ); unfortunately I now cannot use the qwebchannel.js script anymore and my css gets screwed :( even loading it with: QFile script_file(":/qtwebchannel/qwebchannel.js"); if(!script_file.open(QIODevice::ReadOnly)) qDebug()<<"Couldn't load Qt's QWebChannel API!"; QString qt_script = QString::fromLatin1(script_file.readAll()); script_file.close(); view->page()->runJavaScript(qt_script); did not help. Since it is a small project and I am on a short deadline right now I will put everything in one html file and mark this question als solved.

I finally found the problème from qt documentation. My solution is to add : QTQUICK_COMPILER_SKIPPED_RESOURCES += testgooglemapwebengine.qrc in my .pro file.

I've decided to report this issue as a bug here. Was you able to reproduce the issue ?

@dheerendra said in QWebEngineView doesn't work with paid proxy.: Since authentication is required, did you catch the signal proxyAuthenticationRequired from webEngine page ? I know now, that i have to use connect method to catch this signal, but i don't know, what do i have to do after.

Anyone has any idea?

These messages aren't critical, you can ignore them. What's important is, that you don't crash the application anymore.

The problem is the same as in your other thread: you need to take care of the destruction order of your qobjects.

Hi. already fixed in https://bugreports.qt.io/browse/QTBUG-46074

resolved !! i've chenged m_pNetworkAccessManager->get(request); by request.setRawHeader("Content-Type", "application/x-www-form-urlencoded"); QByteArray par=""; m_pNetworkAccessManager->post(request,par);

I had the same question as you,I think ,maybe your project is short of the '.js' file. You can add the '.js' file to the project-resource , then have a try. By the way ,In my project , It has the ',js' file,but there is still a quetion. In my projtct,I want load a HTML that use google maps api and show maps offline ,oc course I have doemloaded the map titles .the HTML can work in any browser, such as chrome, IE ,firefox and so on,but the html doesnot work in Qt5.6.0 which I use the QWebEngineWidget class. The error is : js: Uncaught TypeError:google.maps.LatLng is not a function js: Uncaught TypeError:google.maps.MAP is not a function So,this is my question,I haven't solved。

@Hans-Dijkema I have yet to try Qt 5.7 beta, but... it seems to me like you haven't installed QtWebEngine?...

@p3c0 That worked, thanks for your help.

Hi and welcome to devnet, If you can reproduce this easily with a minimal compilable example, you should go to the bug report system to see if it's something known. If not please consider opening a new report providing that example and the guidelines to trigger the bug.

Just an FYI, disabling network adapters (used by virtual machines) in Device Manager solved the sluggishness for me.

@ThatDud3 well, Qt 5.5 have been released, but I don't see nothing about proxy in QWebEngineSettings XD It is real problem...

AFAIK yes, but you still need a build of ffmpeg that supports h.264.

QWebEngineView use IE's proxy settings, just like google chrome
