  @JonB I adapted the code in the link you provided. It's really cool in simulating a smooth transition to trick the eyes that the page is loading from 1 to 100. But it doesn't help the onLoadingChanged connection in updating the loading progress status of the Qwebengineview.

  In your runJavascript function either you emit a signal or you can call a function of the save class and then pass the value in that function. page()->runJavaScript(js,[this](const QVariant &v) { newFunction(v); } Then in newFunction you can carry out the further code.

  Hello Sebastian, I am seeing the same problem. The last frame on the stack after a crash points to qwebengine core qt5\qtwebengine\src\3rdparty\chromium\base\process\memory_win.cc @ 41 but its actually capturing various other exceptions from our application. Were you able to solve the problem? Thanks!

  @forca maybe you need to do some additional steps From QSslSocket documentation: Describes the peer verification modes for QSslSocket. The default mode is AutoVerifyPeer, which selects an appropriate mode depending on the socket's QSocket::SslMode. QSslSocket::QueryPeer 1 QSslSocket will request a certificate from the peer, but does not require this certificate to be valid. This is useful when you want to display peer certificate details to the user without affecting the actual SSL handshake. This mode is the default for servers. Note: In Schannel this value acts the same as VerifyNone. And looking at this QWebEnginePage browser example, check the Downloading Favicons code snippet, which may help you accessing the underlying QSslSocket

  Hey everyone. I had to remove the setScheme() left over from the QWebView code. Then, voila, it worked fine. from: _rplFuncDocBaseUrl = QUrl (embedHelpPath); _rplFuncDocBaseUrl.setScheme ("file"); to: _rplFuncDocBaseUrl = QUrl (embedHelpPath);

  @jsulm said in ES6 modules in QWebEnginePage?: Where is _moduletesta.mjs located? It's in Anki's collection.media folder, the only folder where Anki cards may load content from. Since it's the only content folder Anki allows, explicit paths are not needed. (I've verified with loading a non-module script and with CSS files, both of which are being loaded correctly.) I've simplified the example somewhat, hopefully this makes things clearer. The example script in my OP should print 42 to the console, but it doesn't. Edit: I've also tried importing from './_moduletesta.mjs' and '/_moduletesta.mjs', neither of which work.

  Finally I builded Qt webengine 5.9.8 with VS 2015 in the windows of English environment, it works OK. The ninja needs python2, but python2 in the GBK charset environment causes compilation errors. Maybe I will rebuild Qt 5.13.0 with VS 2017, but not now.

  @hsynkrkmz From posts I have seen elsewhere: this happens with QtWebEngine, sometimes. It seems to very picky about where it gets destroyed. If you are waiting for definitive answer, you might like to try moving around where/how you destroy it and see if different behaviour.

  @sun708 One more difference i could find is, in case of failure, dwrite.dll that is loaded is of version 6.2.9200.22774. In case of success, its version is 6.2.9200.22164. Both of them are run on same machine.

  @Hetal Hi, you may find the previous post below useful to your problem: https://forum.qt.io/topic/70968/qwebchannel-js-uncaught-referenceerror-qt-is-not-defined This previous post assumed that you have no control over the js code that will run in your QWebEngine. If you do have the control over the js code, you may simply register your C++ obj using //your C++ code here QWebChannel* pWebChannel = new QWebChannel(this); pWebChannel ->registerObject(nameOfC++Obj, pC++Obj); QWebEnginePage *pWebPage = new QWebEnginePage(pWebProfile); pWebPage->setWebChannel(pWebChannel ); add the following part to your js code: //your js code here <script type="text/javascript" src="qrc:///qtwebchannel/qwebchannel.js"></script> if (typeof qt != 'undefined') { new QWebChannel(qt.webChannelTransport, function(channel) { if (typeof channel.objects != 'undefined') { YouJsObj = channel.objects.YourC++Obj; } }); }

  I wrote to chromium developers, so, here is the summary It is not a crash, it is a failed debug assertion It happens if: you use webview's chromium backend (recent versions, old versions don't have this assertion) some part of you code consumes COM and that code's thread is not explicitly initializing COM via CoInitialize or CoInitializeEx My code uses a library that was not properly initializing COM in its threads before calling CoCreateInstance. Calling CoInitialize should fix my issue, but I cannot prove it until I have access to that libraries source code. What is left to be done by qt/webview team is to fix the failed assertion on "Chrome_InProcGpuThread" which is not created by user.

  Hi and welcome both to devnet, Did you try that with the released version of Qt 5.13.0 ? On which platform do you have that issue ? Can you provide a minimal compilable example that shows that behavior ?

  The problem was solved after running the application from under exe file (not from under QtCreator).Everything works faster under exe file. Apparently the launch and initialization of the Unity engine is slowed down by QtCreator. When the application is running under exe web project launch in Web Engine View takes 2-3 seconds (on an old PC 7-9 seconds).
