Webengine example fail with "Unknown module(s) in QT: webengine"
-
@mrjj As for these binary packages, credits go to CI infrastructure of The Qt Company, and personally to Simon Hausmann who helped a lot with integration of new QtWebKit's build system into Coin.
Also credits go to Vitaly Slobodin and other contributors of revived QtWebKit, who contributed lots of patches enhancing Windows and macOS support. Without them, it could happen that only Linux would be supported.

Do you know if the 5.8/Webkit binaries support a mix of HTML and JavaScript on the same page?
A real ancient version of WebKit I was using in Qt4.7.2 did not...which is what has prompted my attempted upgrade to Qt5x/WebEngine.

Like written in the documentation I linked, QtWebEngine is not available with MinGW for the reason I have already given.
As for Visual Studio, yes, it's up to you to install it. It has always been the case. Microsoft doesn't allow any third party to bundle its development suits.

You need to install Qt 5.8.0 and extract QtWebKit binaries that you can download from link that I've posted above.

Hi

https://github.com/annulen/webkit/releasesI am still using the qt 5.5.1 mingw version, and using the default webview in that QT version. One BIG problem I met is memory leak seems still in qt 5.5.1 mingw version ...
Is the memory leak problem resolved in the qtwebkit-tp5-qt58-mingw530-x86.zip or qtwebkit-5.212.0_alpha2-qt59-mingw530-x86.zip from https://github.com/annulen/webkit/releases ?

I just tried qt-opensource-windows-x86-mingw530-5.8.0.exe and qtwebkit-tp5-qt58-mingw530-x86.zip, For one of my project works well with qt 5.5.1 mingw, now got below error when compiling, anything I should modify? Or anything missing?
Thanks a lot!
Best regards, Jason

What I am talking about the memory leak, is something as below:

Please try it out, IIRC I couldn't reproduce that issue.
Also, don't use
QWebSettings::setObjectCacheCapacities(0,0,0), this indeed was causing leaks in the old versions, and WebKit isn't really tuned or even tested to operate with no cache at all. -

BTW, is there any estimate target date for the beta or stable version? Thanks again.

Hello @Konstantin-Tokarev ,
I tried with 5.8.0 and 5.9.2 and your corresponding release of QtWebKit, seems still the same symptom, the memory will keep increasing if I refresh the page repeatedly.
BTW, the html pages I used are generated via vuejs, is that OK?
Thanks a lot.
Best regards, Jason

It now says Qt Webengine component is only supported for MSVC 2017, took me a while to figure out.
