QtWebEngine

Hi, You should take a look at the bug report system, there might be something there about that

Thank you! The post was very informative.

@pankaj4288 Can you send data from c++ object back to html/js? If so, do you have suggestion on what should be done different in my question here ... with that code I an unable to get variables in html/js.

Your demo is long over now, but try disabling not-connected network devices, as suggested here: https://bugreports.qt.io/browse/QTBUG-44763t Worked for me when running the FancyBrowser example code

I got a reply from the web engine mailing list, and turns out the answer is when both conditions 2 & 3 are met. Documentation: https://code.google.com/p/chromium/codesearch#chromium/src/content/public/browser/web_contents_observer.h&q=file:web_contents_observer.h function:DidFinishLoad&sq=package:chromium&l=197

You're welcome ! No, you can do it yourself using the "Topic Tool" button :)

@mcosta Your wording of my question was better. Thanks for the reply! I guess I was being lazy and hoping to avoid having 2 functions to call one. :-D

@ratwix I have found the solution : for each new connection, dynamicaly create a new WebEngineProfile with offTheRecord and new storage name (needed ?) and assign it to the current WebEngineView

Have you guys tried 5.5.1? Wondering if theses issues still exist.

Here are the screenshots depicting the problem: [image: 2nbt26u.jpg] [image: 2uo2dg9.jpg]

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

Hi Rahul, I am looking something similar i.e. logs of Qt framework. Refer https://forum.qt.io/topic/58566/how-to-print-logs-qdebug-qwarning-qcritical-qfatal-of-qt-framework-libraries-itself Try using --log-level=0. It might work in your case. Thanks, Anant Agrawal

have you tried a simple alert from your Qt to Js? QString jsCode = "alert('helloWorld');"; ui->webView_studio->page()->mainFrame()->documentElement().evaluateJavaScript(jsCode + "; null"); if this works then the problem is the syntax of your javascript inside Qt.
