Does the app work if you start it with --single-process added to the command line?

I've got the same situation on my iMX6 with Yocto Rocko. Any solution for this issue? Is the same situation on new release Sumo or Thud?

I use Windows and msvc 2015 compiler.
I Installed a qt-opensource-windows-x86-5.9.2.exe. Then I changed a very little some headers in qtwebengine module. Then, I need to rebuild it. I opened configurated by Qt console for msvc2015 x86_64 compiler, go to the src/qtwebengine, typing qmake and after that nmake. nmake only outputs

Microsoft (R) Program Maintenance Utility Version 14.00.24210.0 Copyright (C) Microsoft Corporation. All rights reserved.

but did nothing.
I downloaded qtwebengine-opensource-src-5.9.2 separately and try to buid it - the same result.
How to rebuild qtwebengine using msvc 2015 compiler?

Hi,

From a quick look at the sources of the module:

Yes it does and yes for iOS and Android, so in your case for macOS, no. In 5.9, the native macOS web view is used rather than QtWebEngine and support for winrt

For number 2, what should your application do ?

Nowadays the software renderer for WebGL works fine. I wonder if there is some easy way to detect if the video adapter is affected (probably intel && being "old") and if that's the case, to switch to software renderer, at run-time - maybe before initializing QApplication? in order to pass --enable-webgl-software-rendering parameter programmatically.

Hi,

Thanks for replying, I solved my issue. I was missing some "#include" in different files.

@mpergand you are right, this line solved the problem. Thank you very much!

@jsulm

Thanks for the suggestion. I forget about ldd and usually notice about missing dependencies when I get an error. It's a great suggestion in this case when I may not see the errors, but I checked and all dependencies have been met.

@sneubert
You're the bomb!!! That was it. I recompiled with the enable plugins flag set and all is working now. Thank you so much for your help. Not sure how else I would have found it.

Looks like adding the use_proprietary_codecs define in .qmake.conf is not allowed by design?, i need to add these changes in order qt 5.8 to pick up the additional WEBENGINE_CONFIG :

#Edit ..\qt-everywhere-opensource-src-5.8.1\qtwebengine\.qmake.conf #Add WEBENGINE_CONFIG += use_proprietary_codecs #Edit ..C:\QT-Build\qt-everywhere-opensource-src-5.8.1\qtwebengine\configure.json #Line 45 "autoDetect": false, into "autoDetect": true,

mark
qtwebengine_resources.pak + qtwebengine_resources_100p.pak+ qtwebengine_resources_200p.pak

In my case this function works:

onFeaturePermissionRequested: { console.log("onFeaturePermissionRequested"); webEngineView.grantFeaturePermission(securityOrigin, feature, true); }

Tested on Qt 5.6 and Qt 5.7 on Desktop and Embedded

Hi,

Did you also install Qt for MSVC2013 ?

Hi and welcome to devnet,

That's a question you should bring to the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.

Hi,

I'd recommend posting that question to the the QtWebEngine mailing list. You'll find there QtWebEngine's developers/maintainers. This forum is more user oriented.

Thanks. I take a look at hat and at http://tishion.github.io/QCefView/

But then we end up in using an extra lib. Something we want to avoid.... :-(

I had the same question as you,I think ,maybe your project is short of the '.js' file.
You can add the '.js' file to the project-resource , then have a try.

By the way ,In my project , It has the ',js' file,but there is still a quetion.
In my projtct,I want load a HTML that use google maps api and show maps offline ,oc course I have doemloaded the map titles .the HTML can work in any browser, such as chrome, IE ,firefox and so on,but the html doesnot work in Qt5.6.0 which I use the QWebEngineWidget class.
The error is :
js: Uncaught TypeError:google.maps.LatLng is not a function
js: Uncaught TypeError:google.maps.MAP is not a function

So,this is my question,I haven't solved。

Solved: the cause was the stub in mesa3d drm backend. It's solved by altering the backend.

Old post but I had the same error; I had to build qtdeclarative BEFORE qwebchannel to solve this error.

@Zevero I had the same problem, is there a solution for the mouse click that doesn't work in the web pages.

alas no luck - so far still the only option is to use command line parameters to your own app - and yes every single embedded web engine sub-process will reuse the same parameters (no luck with different proxy per tab problem)
e.g. if you try
MyApp.exe --proxy-server=host:port
and your app opens 10 tabs the same proxy it will be reused by every single tab/or browser/or sub-process/
pretty much the same as setting global proxy (at application level)

https://bugreports.qt.io/browse/QTBUG-59490

BTW: if they implement the above they need to decide which has higher priority - global app level proxy or per web engine sub-process

Hi

May I ask how you got this to build?

I am trying to compile Qt with the following configuration (for Raspberry Pi):

./configure --prefix=/usr -release -opensource -confirm-license -c++11 -no-largefile -no-qml-debug -system-zlib \ -no-journald -system-libpng -system-freetype -system-libjpeg -system-sqlite -openssl -no-pulseaudio -alsa \ -no-sql-db2 -no-sql-ibase -no-sql-mysql -no-sql-oci -no-sql-odbc -no-sql-psql -no-sql-sqlite2 -no-sql-tds -nomake examples -reduce-exports \ -no-directfb -no-linuxfb -eglfs -no-xcb -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/usr/bin/ -sysroot /

Here is my patch:

diff --git a/qtwebengine/tools/qmake/mkspecs/features/functions.prf b/qtwebengine/tools/qmake/mkspecs/features/functions.prf index ef0320d..5abaecc 100644 --- a/qtwebengine/tools/qmake/mkspecs/features/functions.prf +++ b/qtwebengine/tools/qmake/mkspecs/features/functions.prf @@ -12,13 +12,9 @@ defineTest(isPlatformSupported) { return(false) } - linux-g++*:!isGCCVersionSupported(): return(false) - !isPythonVersionSupported(): return(false) - linux-g++*|win32-msvc2013|macx-clang: return(true) boot2qt: return(true) - skipBuild("Qt WebEngine can currently only be built for Linux (GCC), Windows (MSVC 2013), OS X (XCode 5.1+) or Qt for Device Creation.") - return(false) + return(true) } defineTest(isPythonVersionSupported) { -- 2.1.0

And it succeeds, but I don't get a message about WebEngine being an unsupported platform. It simply does not build that module. I tried to follow this reference here, but had no luck either: https://forum.qt.io/topic/48223/webengine-raspberry-pi/2

I am building native, not cross, on Debian Jessie.

Thanks in advance,

Sam

Waiting online~~~

Well, it was caused by a QGraphicsEffect on the QWidget.
After removing it, the QWebEngineView worked without any flaws. weird.
