@JonB Thank you so much! I see this is different than I thought.

Works good!

@gouneken said in how to enable using QWebEngineWidgets module after downloading?:

I'm using a module from another version of qt or something else

You, of course, have to install it for Qt version you're using

First off, thanks for your time.

I've tried that yeah - you can see that I've made the default index_file "qrc:/index-light.html" in the load_args function. It's here in the code.

When writing to qDebug() the string is correctly "qrc:/index-light.html", though nothing is shown in the webview... I've tried changing it to "qrc:/light.css" and then it correctly shows the css in the webview (the code in plaintext).

Hi,

Because of chromium minimal compiler requirements. Nothing Qt can do about.

Either use an older version or update your compiler to VS 2019 which is backward compatible with VS2017 and has less bugs.

https://stackoverflow.com/questions/58875159/how-to-ignore-ssl-certificate-errors-with-qwebengineview link helped me to resolve the issue. Now HTTPS page load after ignoring ssl warning is fine. Thanks for ideas :)

I finally found the problème from qt documentation.
My solution is to add : QTQUICK_COMPILER_SKIPPED_RESOURCES += testgooglemapwebengine.qrc in my .pro file.

Just wanted to say thanks! I ran into the same issue (building qtwebengine) on Ubuntu 18.04 host and this fixed it.

I'm adding it to my personal list of prerequisites for my Boot2Qt Yocto builds....

@LovelyGrace said in webenginewidgets on .pro of library produce error:

but when I am trying to build the whole project from sub dir project including the library and the console, it produce the error

You need to add Qt += webenginewidgets to your console project as well.

I use QCoreApplication::setAttribute(Qt::AA_UseOpenGLES); It can really screen bugs。but , error too;

I received an answer from Qt support, it solved the problem. Their answer below:

On a virtual machine the OpenGL support might not be enough for rendering Qt WebEngine, so the quickest way to check if this is the case here is to do:

set QT_OPENGL=angle

on the command line or add:

QGuiApplication::setAttribute(Qt::AA_UseOpenGLES);

before the creation of the application object

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

@allenck
ahh, yes that would do it.
It can tell Qt to look from plugins in other places.

Good catch :)

Ok this put me in the right direction, having subclassed both the view and page, and using createWindow and acceptNavigationRequest, I see how this all works now.. Thanks!

@Charles-Cai I know this thread is very old but do you got any solution? I am stuck in same problem. I want to load HTML page containing java applet using QWebEngineView. Can't find any way out. Your input can help me. Thanks

@Hans-Dijkema I have yet to try Qt 5.7 beta, but... it seems to me like you haven't installed QtWebEngine?...
