  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 Thanks for the update. We'd need support on Windows for Assistant, so I guess there is still demand for WebEngine support there. I started this thread: https://lists.qt-project.org/pipermail/development/2019-May/035920.html

  How did you debug this? Is there any logging available?

  Yes, there is JS console in Web Inspector. Also it's possible to get console messages via API

  Also, does QtWebkit use some non-recent version of Webkit engine?

  5.212 (which is currently shipped in Ubuntu) is based on WebKit branch from 2016

  Qt & V8

  When V8 came out was around the same time I stopped programming in C++. I still love QT but was very under impressed by the JavaScript engine in QML. I have moved most of my focus since on JavaScript and Node.js (and even Microsoft Jscript.net for a time) because of the speed at which I could develop complex business applications and network applications.

  My love of V8 makes it emotionally hard to accept a new V4VM but the arguments made in here seem valid and I think this may convince me to move ahead and try out QML again. It's either that or Electron.

  In terms of the future and general popularity of QT, there could be nothing better than JavaScript QT. going head-to-head with Electron. However, my personal preference would be doing this without XML. I wish I could just code QT in JavaScript similar to how it's done with C++. There is a QT npm for node.js but I couldn't get it to compile... clearly not well maintained.

  Hi,

  from git I get the version 5.212.0. After the compilation I will get a incorrect version error from cmake in digikam. I should use the exact version 5.12.x.
  Is ther an error in the git sources or did I a mistake?

  @illia said in Using Web technologies with Open Source Qt Creator:

  I downloaded it from the Qt main website (the open source version).
  https://www.qt.io/download

  I installed it as the instruction told.

  The installer contains many components. Which ones did you select?

  You probably want to select these 3 things, at least:

  Tools > Qt Creator Qt 5.12.1 > MSVC 2017 64-bit Qt 5.12.1 > Qt WebEngine

  No. #1 is selected by default, but the others are not.

  You also need to install Visual Studio 2017 directly from Microsoft. Qt WebEngine is not compatible with the MinGW compiler.

  As @SGaist said, it is still possible to use Qt WebKit. However, the setup is harder.

  Is it possible to intercept the http response and store them locally?

  You can replace QNetworkAccessManager instance of QWebPage with object of your own subclass and intercept any requests

  What are the other techniques in qt that can help ?

  You can use standard HTTP caching, e.g. via installing QNetworkDiskCache on QNetworkAccessManager instance of QWebPage. Behavior of cache is controlled by HTTP headers

  Hi,

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

  You should update Qt in any case however that won't change anything for QtWebKit. The module does not compile in static mode because of its underlying dependencies.

  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 ?
