What is the performance of an HTML5 application in Qt?

Question

HTML

Good day! I recently started learning Qt and in Qt Creater I discovered the project type HTML5 Application (uses HTML, CSS, JS to create the interface and is rendered by WebKit). This solution seemed very attractive to me for easily creating beautiful and highly scalable interfaces. But I am tormented by doubts about performance and expediency (after all, a webkit is used to draw interfaces). Can you say something about it? What is it, for example, in comparison with QML or Microsoft WPF (which uses XML markup, which is also convenient).

Answer 1

Depends on what application you will write on.
If C++, then Qml is better. Binding properties, calling methods, using plus models from Qml is much easier. It was created for this.
If you only have JS, then the HTML5 option is probably preferable.

Answer 2

I made a window on qml and on widgets (QWebView) to display a yandex / google map, on widgets it was noticeably faster, but slower than in a browser (chrome).
