Qt WebKit

@U7Development said in Web Application development...: can i develope my app using Qt Creator but with Cutelyst framework ? Yes. Stock Qt Creator understands the default cmake project that Cutelyst creates quite well. I think Cutelyst also provides their own, customized version, but I have never used it.

In RPM you can only have things (files, packages, "provides") installed by RPM as dependencies of your package

@msauer75 You have to rebuild digikam with new Qt and QtWebKit libs that you are using

Then update Qt and check if standalone QTcpSocket is working properly with your proxy settings

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

thank you for the explanation.

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 and welcome to devnet, Are you trying to integrate the KWebKit framework into your application ?

@Wowalive This is not possible at the moment

Interesting. FWIW, in 5.212 tiling backing store is not supported and this setting should have no effect

@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

@Konstantin-Tokarev thanks

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.

@SGaist Can you help me with this case? I think QT 5.3 has a problem with Webview, then I plan to install qt5.12 (which I'm asking for help in another topic). what do you think bro? thanks.
