    Hi and welcome to devnet,

    Start your application with the QT_DEBUG_PLUGINS environment variable set to 1. This will show what happens with the plugins loading.

    Thank you for your reply. This is the output of application when I set QT_DEBUG_PLUGINS environment variable to 1.

      Excuse apparently I can't upload the file here.

      These lines are available in my log:

      [...]
      loaded library "/gnu/store/644m36biz8f2n0j8bjw2k2m7051584iy-qt-5.11.3/lib/qt5/qml/QtQuick/Controls/libqtquickcontrolsplugin.so"
      Found metadata in lib /gnu/store/ilz7sxcwg2gd0qffavsp1vm4g6bn3b5d-qtwebview-5.11.3/lib/qt5/qml/QtWebView/libdeclarative_webview.so, metadata=

          "IID": "org.qt-project.Qt.QQmlExtensionInterface/1.0",
          "MetaData": {

          ],
          "version": 330499
      }
      [...]
      

      Where is the problem?

        Please provide the full log. This entry alone doesn't contain all the data needed to check what is happening.

            How did you install Qt ?
            What version is it ?
            Are you using an out of source build of the example ?

              @SGaist I'm using GuixSD distribution (Linux) and install the Qt by its package manager guix.
              The 5.11.3 is available in guix package repository and I installed it. Also I'm using this example:

                Might be a silly question but did you check that your distribution provided Qt is complete ?

                  @SGaist I'm not sure, but I know that qtwebengine removed from the qt package.

                  https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/qt.scm#n143

                  What's your idea? Do you see any problem in log file?

                    You have to talk with the guys from the guix project about that matter.

                    The QtWebkit module has been deprecated and removed but not QtWebEngine. Note that @Konstantin-Tokarev is working on reboot of QtWebkit.

                      @SGaist Thanks for your good contribution,
                      How can I make sure that my distribution provided Qt is complete?

                      The QtWebkit module has been deprecated and removed but not QtWebEngine.

                      I mean QtWebEngine is removed from guix qt package. (based on this link)

                      Did you see any problem in the log file?

                        Well, you have to talk with the folks of your distribution.

                        As for your trouble, I just remembered and IIRC, the QtWebView module is backed by QtWebEngine on platforms that don't provide a native web widget like iOS.

                        So you might be experiencing that.
