Webengine example fail with "Unknown module(s) in QT: webengine"
-
I don't believe QWebEngine is installed by default. Go to your Qt installation folder and run the Qt Maintenance tool. Select the option to 'Add or remove components' and click next. If you expand the the tree for your Qt version (e.g. Qt 5.7) you should see a component called "Qt WebEngine" in the list. Make sure that is checked and click next to install it if required.
@aatwo Thanks for reply! Although as I stated the webengine is checked and installed. I have tried installing under linux also but with the same result!

Hi and welcome to devnet,
QtWebEngine is only available for Visual Studio 2013 and 2015.
When you say: "change the Kit", do you mean you installed Qt for either VS2013 and VS2015 ?

@SGaist Yes I installed the for VS2013 and 2015 also. I'm also installed VS2015 application, but after the QT.

@magiclevinho When I go to the Projects tab -> manage kits, then for the msvc 2015 it says no compiler set. How can I set a compiler?

- "C:\Qt\5.7\mingw53_32\bin"
Just so we are very clear on this.
The Qt Vs201X kits do NOT work with mingw.
You must also download the full vs 2013 or 2015 COMPILER from microsoft
and switch to that full compiler. So Besides the Qt kits, you should also have installed
the actual compiler. as its not included same way as mingw kit.
(its not allowed) -

(its not allowed)@mrjj Thanky for the reply! I had to make my first c++ project in VS 2015 and it installed the neccessary compiler!

So you have it all working now ?

After some time I found this information, which does not seem to be published elsewhere:
"MSVC2013 is not supported anymore in Qt WebEngine"

https://www.visualstudio.com/downloads/#visual-studio-community-2015-with-update-3-freeProject ERROR: Unknown module(s) in QT: webenginewidgets
Initial searching for a solution on the web shows this has been a problem for a number of years.
QTBUG-43614 webenginewidgets examples does not build on Windows
https://bugreports.qt.io/browse/QTBUG-43614
QTBUG-44108 webenginewidgets examples does not build on Windows (second try)
https://bugreports.qt.io/browse/QTBUG-44108Both of the above QTBUG items are marked as closed. Obviously they are not.
Yes..I have QT += webenginewidgets set in the .pro file.
Windows7 Pro SP1 32 bit OS. Creator4.2.0 Qt5.7.1. from this download..
qt-opensource-windows-x86-mingw530-5.7.1
The exact same project built on OSX using Creator4.2.0 Qt5.7.1. compiles and runs properly.
Do I need to download and install BS compilers from Microsoft to get this to work? If so, do I need a different Qt download in order to use the MSBS compilers??
Do I need to upgrade to a different OS..Win8 or Win10? Or Maybe Win7 Pro 64 bit??
Is there a solution for Windows7 Pro SP1 32 bit OS??

The QtWebEngine platform notes explain what is needed to build the module.
QtWebEngine is using the Chromium project as backend so it depends on what platform they support. If you would like to have a MinGW build of QtWebEngine then you should rather push this to the Chromium project.
On a side note, there's @Konstantin-Tokarev QtWebKit reboot project that might interest you.

Note that we provide QtWebKit TP5 binaries compatible with official Qt 5.8.0 MinGW build: https://github.com/annulen/webkit/releases/tag/qtwebkit-tp5

Thx for the reply. I made a mistake downloading the open source install.
I am now using: qt-unified-windows-x86-2.0.5-online.exe...and have a current Commercial License for Application Development..all handheld and desktop environments are covered.I tried installing Qt5.7.1 for MinGW but there were no QtWebEngine libraries.
I tried installing Qt5.7.1 for MSVC2015 and it had the QtWebEngine libraries, but no compiler.I am now re-installing 5.8, 5.7, and 5.6. Maybe one of those will have the libraries I need.

Thx for the heads up.
Are the 5.8/Webkit binaries also available for MacOS-clang64 environments?

@PSI_lbc Yeah, see the same link. Also there are binaries for 64-bit Linux and VS 2015 (both 32-bit and 64-bit)

@Konstantin-Tokarev
Thank you for all your work. its a huge task for a beginner to build webkit so your project
is very welcome. -

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.

Of course, yes!
