Hi,

Might be a silly question but did you add QT += webview to your .pro file ?

Karwan · wrote on 7 Feb 2019, 19:52

yes, i added QT += webview to .pro , but it's same thing , iam using MSVC 2017 kit

Can you check whether you have the QtWebView libraries in your installation ?

Konstantin Tokarev · 9 Feb 2019, 19:12

Did you enable QtWebEngine module when installing Qt?

Karwan · S SGaist 7 Feb 2019, 22:44

@SGaist i checked C:\Qt\Qt5.12.0\5.12.0\msvc2017_64\lib
there's the libraries of QtWebView.
i tried to import it but it didn't work!

Can you start your application with the QT_DEBUG_PLUGINS environment variable set to 1 ? This should give some additional clues.

Karwan · S SGaist 9 Feb 2019, 20:51

@SGaist By Adding QT_DEBUG_PLUGINS=1 to .pro , Fixed my problem , Thank you for everything @SGaist :) <333

I have the same issue. I also tried adding QT_DEBUG_PLUGINS=1 to .pro as well as setting the same environment variable, but these did not help..
I am using msys/mingw64 Qt build: http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-qt5-5.12.1-2-any.pkg.tar.xz
In the log I can the warning: (qwebviewfactory.cpp:92) No WebView plug-in found!

Hi,

The QtWebView module uses QtWebEngine on Windows. And as already written, this module is only available with MSVC2017 because of chromium.

In Qt 5.15.0, there will be similar error like this when deploying in Windows. My solution is to put

QtWebView::initialize();

after

QGuiApplication app(argc, argv);

There will be a warning said: QtWebEngine::initialize() called with QCoreApplication object already created and should be call before. This is depreciated and may fail in the future. but it's working.

@Karwan QT_DEBUG_PLUGINS=1 works! :)

@kdsurya QtWebView::initialize after QGuiApplication app(argc, argv); works! :)
