  Feature-wise comparison of QtWebKit reboot with official sources:

  https://github.com/annulen/webkit/wiki/Comparison-with-QtWebKit-5.6

  Note that we are very close to feature parity now, i.e. there are very little features that work with legacy QtWebKit and are not yet supported with reboot, and their number is constantly lowering.

  @Konstantin-Tokarev
  I found this command to identify the qtwebkit version, but not sure about it:

  apt-cache policy libwebkitgtk-3.0-0

  the output is :
  libwebkitgtk-3.0-0:
  Installed: 1:2.4.1-1rpi53rpi1g
  Candidate: 1:2.4.1-1rpi53rpi1g
  Version table:
  *** 1:2.4.1-1rpi53rpi1g 0

  2.4.9-1~deb8u1+rpi1 0

  @Konstantin-Tokarev Thanks. Its the same error again. Maybe its because I copy webkit in QT folder and let qt build the webkit. I haven't tried building it separately. I will see if I could built it separately and soon update the status here.

  Your installer based Qt has absolutely no idea of what you have on your system and you should in any case not mix libraries from different versions of Qt.

  There's no "Qt SDK" package in Ubuntu. You can start with qtbase5-dev and then add the dev packages corresponding to the modules you want to use.

  @Konstantin-Tokarev I'm afraid no, I'm not a JS dev. The problem is that JS code I posted in the first message does not work with errors

  https://cdn.3dmapping.cloud/18.1.4/javascript/orbitgt_3dm_sdk.js line 1: TypeError: a.call is not a function. (In 'a.call(this,t,e,n,r)', 'a.call' is an instance of ProxyObject)

  I was able to identify that calls Array.from() and Object.assign() are missed, but maybe there are more.

  Hi @nlazovic-0,

  Using QWebView::load() that takes a QNetworkRequest would be the way to go as you can set whatever headers you want, so you can make the adjustments there. However, I would have thought that the server is at fault here as it is a request, it doesn't have to go to HTTP/2.

  You need to provide a bit more context. A minimal compilable example would be best with also a sample svg file that triggers this.

  By the way, which version of Qt are you using ? On what platform ?

  @Konstantin-Tokarev Hi Konstantin,

  Thanks for your quick reply. In case the SVG support is disabled, would it still be possible to display inline SVG images (the first polygon image above)?

  Also, could you please suggest how to check if SVG support is enabled/disabled, and how to enable in case it is disabled.

  Thanks.

  JS handler can be added via evaluateJavaScript, and Qt bridge used to provide actual handling via exported QObject

  I've considered adding API for C++ event hadlers, but that would require some development effort

  @Konstantin-Tokarev said in Linux: build QtWebKit against a specific version of ICU?:

  @agarny said in Linux: build QtWebKit against a specific version of ICU?:

  From what I can tell, both libQt5Core.so.5 and libQt5WebKitWidgets.so.5 depend on the following two system libraries, which themselves depend on the system version of ICU

  Oh. QtWebKit binaries are provided for use with official Qt builds, not system libraries

  First, I obviously meant libQt5WebKit.so.5 and not libQt5Core.so.5.

  Second, sure, it's just that when you do an ldd on the QtWebKit binaries, you get told that both the system version of ICU and the version you requested (56.1 in my case) are needed. So, I got a bit confused back then, although I now understand the reasoning for it.

  @Konstantin-Tokarev Here is a simple html sample:

  <html> <head> <title>Test</title> <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet"> </head> <body> <i class="material-icons">face</i> </body> </html>

  You can load it into QWebView and see that the icon is displayed as italic.
