Unsolved get source code from QWebEnginePage in QWebEngineView
I want to get the source code of a web page opened in QWebEngineView I use toHtml() function in QWebEnginePage Class like this
QWebEnginePage *page = ui->widget->page();
QString HTML = "";
page->toHtml([&HTML](QString html){qDebug() << "code \n\n\n" << html;});
the source code of html page appeared in qDebug good without problem
the problem here is when I want to use HTML string outside the function when I show the size of the HTML varible it is equal to zero
I tried this
QWebEnginePage *page = ui->widget->page();
QString HTML = "";
page->toHtml([&HTML](QString html){HTML = html;}); // crash
qDebug() << "i want to use HTML here outside the function = " << HTML;
but the app crash show so what should I do so I put the HTML data in the HTML variable so I can use it outside the function
Thanks in advance

Unsolved QObject registered to QtWebChannel cannot be accessed in javascript world synchronously when used with Qtwebengine
We are planning to use Qt5.7.1 and have some existing applications on qtwebkit which expect to access methods in javascript world synchronously. These are slot methods of QObject registered using addToJavaScriptWindowObject using to QWebPage frame.
When we port to Q5.7.1 these are registered to QtWebChannel object of QWebEnginePage. Now these methods are asynchronous.
Is there any alternative for this to make these calls synchronous?
Given that QtWebengine uses chromium and it internally spawns a different process and since these queries happens over IPC may be these are designed as async. But chromium V8 also supports synchronous IPC communication, so is it possible to support this in future if there is no way to acheive this currently?

Unsolved qwebengine + webgl does not work on some windows hardware
Hello,
We've run into a problem with viewing webgl via qwebengine. With a small test application in Qt 5.9.1,
QCoreApplication::setAttribute(Qt::AA_UseDesktopOpenGL,true);
QApplication app(argc,argv);
auto webWidget = new QWebEngineView();
webWidget->settings()->setAttribute(QWebEngineSettings::WebGLEnabled,true);
webWidget->setUrl(QUrl("http://webglreport.com/"));
webWidget->resize(1000,800);
webWidget->show();
return app.exec();
the test page states that webgl is not available, and indeed pages with actual webgl content are not viewable. "× This browser supports WebGL 1, but it is disabled or unavailable."
On a recent laptop with Intel HD P530, webgl sometimes works if --ignore-gpu-blacklist is provided on the command line. On a Surface Pro 3 with Intel HD 5000 graphics (our actual target device), it doesn't work at all. On both computers, viewing the same web page in Chrome browser works fine.
We tried rebuilding qt with the patch described at the end of this thread, but observe the same behavior (except that 'opengl context cannot be shared' messages disappeared).
We've also tried using different opengl versions (desktop, software, and gles) via
QCoreApplication::setAttribute(Qt::AA_UseDesktopOpenGL,true);
No combination of flags seems to work. The issue also does not seem to be fixed in qt 5.10.0 alpha release. Can anybody provide assistance with this issue, or give us guidance as to how to track down what's going wrong?
Thanks in advance.

Unsolved qtwebengine + webgl on windows, black geometry?
On some windows hardware, using a qwebengineview showing a page with webgl, objects appear very dark or black. Though it may be a texturing issue, nearly all of the examples on webglsamples.org and threejs.org seem fine except lighting-based ones.
For instance,
https://threejs.org/examples/#webgl_lights_pointlights or
https://threejs.org/examples/#webgl_lights_hemisphere
the main geometry is completely black when viewing via qtwebengine on our surface pro 3, but on the same computer looks fine via chrome browser. And the same qtwebengine app works fine on a laptop with nvidia graphics.
Any ideas on what's going on here?

Unsolved QtWebEngine YouTube live stream shows only spinner.(with using Flashplayer)
Re: How to stream live content from YouTube using QWebEngineView
Hi out there. I have been using the advice as mentioned in the link above, as I also did hit the HTML5 problem when wanting to play a YouTube live stream. It is also not working in the Qt Demo Browser example. So do not know how to resolve.
Problem:
I do not get a YouTube live stream in the window. It does continue to spin (hourglass), as if it is loading. When I slide the YouTube progress bar back I do see the historical snapshots passing by.
Question:
Who know the solution for this problem?
Set-up:
- Windows 10, 64bit
- QT version: C:\Qt\5.9.1\msvc2017_64
- Installed Flashplayer: https://get.adobe.com/flashplayer/
- C++ coding, snippets:
webview = new QWebEngineView;
webpage = new QWebEnginePage;
webpage->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);
.....
webpage->load(QUrl(https://www.youtube.com/embed/live_stream?channel=UCrYJITU7pDh73ovCUQ_sUPg));
webview->setPage(webpage);
