  @sirhc79
  I think the question is about "Chromium" rather then "Chrome". And may be better asked outside of Qt.

  I came across https://stackoverflow.com/questions/22999829/disable-chrome-pinch-zoom-for-use-in-kiosk. I know it's more Chrome than Chromium, but there might be some ideas there (e.g. JavaScript), or it might confirm that you will difficulty....

  I'm actyally having the same issue!
  Are you using yocto rocko with an imx6 module? I've see that if you're trying to load local html pages in the qtwebengine .. it's working. I suppose is due to the version of chromium on which qtwebengine is based.

  Did you succeeded in get it work?

  @kuris996 , WebView uses different backends on Android and Windows: On Android it is the native browser, on Windows it's Qt WebEngine.

  For Qt WebEngine, I suppose HLS uses codecs that need to be licensed. To get them, you need to compile Qt WebEngine yourself with a -webengine-proprietary-codecs configure flag (see also https://doc.qt.io/qt-5/qtwebengine-features.html#audio-and-video-codecs). In addition, you need to make sure to license them properly.

  @vithom said in Windows versions earlier than 8 are not supported:

  Does this mean that QWebEngineWidget can't be used in windows 7 ?

  Thanks

  hi,

  short answer, yes

  as far as I know, QWebEngineWidget is based on Chronium api and looking here google says it should work with win 7 and newer, so no Idea why it doesn't work with win7
  maybe the version used to build QwebEngineWidget for Qt 5.11 does no longer support Win7? You'll have to check the release notes of 5.11 what version of chronium is used and verify that.

  hi
  I try to use qwebengineview to load a page whcih contain flash. But it notice can't install flash. I have use the code like below to enable the plugin.

  QWebEngineSettings::globalSettings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);

  And copy pepflashplayer.dll and manifest.json from Google Chrome to C:\Windows\System32\Macromed\Flash and then in main() or MainWindow() .

  But it seems not work. it still notice can't install flash plugin.
  I am using the 5.9.1. Is there any version limitation for Chrome browser? How can i know it adapt to my Qwebengineview?
  Any one can help ?
  Thansk very much!!

  Unsolved How to make QtWebEngine work on Windows 10 32 bit?

  Hi, and welcome!

  @PC-LX said in How to make QtWebEngine work on Windows 10 32 bit?:

  p.s. Why is QtWebEngine not supported on Windows 32 bit? That caught me by surprise!

  It is supported, but no pre-built libraries are supplied. This is because Qt WebEngine uses Chromium internally, and this version of Chromium only supports MSVC2017 on Windows. However, the Qt Project only supplies the 64-bit version of Qt for MSVC 2017.

  To get the binaries, you'll need to build the 32-bit version of Qt for MSVC 2017 yourself. This can be quite a lengthy process; are you prepared to do this? If so, get started at https://wiki.qt.io/Building_Qt_5_from_Git (Note: The instructions for building Qt WebEngine seem to be missing. I've never done it myself, so I'll let someone else chime in with the details)

  Thank you for your replay.
  My router doesn't have an API. Or at least I didn't find one.
  Do you know a router that has an API suitable to be used with Qt?

  Thank you very much.

  Also, it is possible to derive from QWebEngineView and override QWebEngineView* createWindow(QWebEnginePage::WebWindowType type) returning this, but this loses the history, i.e. user can't navigate Back.

  Hi,

  If you want to use QtWebEngine you have to upgrade to at least VS2015. That's nothing Qt related, the chromium project which QtWebEngine is built on top has a hard lower limit on VS2015.

  It's in the QtWebEngne Windows platform notes.

  I fixed my problem by editing qwebchannel.js to wrap updated properties to QObjects

  this.propertyUpdate = function(signals, propertyMap)
  {
  // update property cache
  for (var propertyIndex in propertyMap) {
  var propertyValue = propertyMap[propertyIndex];
  object.propertyCache[propertyIndex] = this.unwrapQObject(propertyValue); //changed to call unwrapQObject
  }
  ...
  }

  after that my property core.currentObject shows up as a QObject type
