areweguiyet VS Azul

The organization behind QT (QT Group) has pretty onerous licensing terms.

My understanding is that it's $3,950 per year just to develop using their libraries on your own computer if you ever in the future intend to commercialize a product using QT. Transitioning from the open source license to the commercial license is something you can do but it's not the happy path and their FAQ seems to indicate that it comes with some sort of penalty.

Something like Slint (Rust based but includes CPP and JS bindings) is not as comprehensive (yet) but it's more modern and the licensing terms are significantly more in line with software industry norms.

GPUI from Zed is also something to monitor: https://www.gpui.rs/

Also, in general you can find an extensive list of Rust-based native UI libraries here: https://areweguiyet.com/

I would suggest that nearly every person on this website is a developer. Both C and C++ let you shoot yourself in the foot quite easily, but at least C++ has RAII.

If you're referring to Rust, it's just not there yet for anything serious: https://areweguiyet.com/

I normally use python to do some quick data analysis, with pandas/polars/pyspark/...

But I've started to use rust more and more in the last few weeks and really start to like it.

Does anyone have experience doing data analysis with rust, and would you recommend it over python?

And are there any resources like https://areweguiyet.com/ but for data analysis?

You still haven't said anything about why those existing frameworks don't count. Again, they are used in production and do exactly what a gui framework is supposed to do. Sure they may not have all the features of the frameworks that have existed a decade before rust even existed but the issue is time not rust itself. They very clearly can be used to build complex UI without inheritance. Since you mentioned it, you should probably actually look at it https://areweguiyet.com/ the page clearly says that GUI frameworks do exist in rust.

The web site https://areweguiyet.com/ has a list of GUI libraries for Rust.

I haven’t tried any yet as I lack the time, but it can be a good starting point.

Iced and Slint where interesting when I looked at that, and Slint may be done by former Qt developers.

I also hope that it is consistent with the goals mentioned at https://areweguiyet.com/

Not sure what you mean but WebRender powers Firefox which definitely works on the desktop.

You can use it to build desktop UI frameworks - see for example https://azul.rs/

I'd been wanting to see this, preferably with JS being optional, and just allowing direct DOM access.

I initially thought this was what Azul was, but it's only just using Servo's WebRender compositor, and rolls its own CSS parser, DOM, and layout engine, so it doesn't benefit from most of the work done on Servo, and supports less CSS features.

https://github.com/fschutt/azul

Both Servo and Fifefox make use of webrender, which is an awesome piece of tech and is well suited to render a web page. Some GUI projects attempted to use webrender directly as well, like Azul and moxie-native

> But no one is saying, "Hey I have a CSS 2.1 compliant rasterizer and compositor that you can use in your C++ or Rust environment!" are they?

There’s actually quite a lot of interesting work going on in that general space, has been in various forms for some years. A couple that immediately spring to mind:

• Azul <https://azul.rs/> builds on WebRender, as used in Firefox. I haven’t looked at it for a few years, but it looks to have grown quite interesting now.

• Blitz <https://github.com/DioxusLabs/blitz> is based on from-scratch implementations of CSS layout and rendering, and wgpu rendering. It’s not usable yet, but is a very interesting concept. If one happens to be familiar with React Native: it’s kinda like that, or React Native Web.

Azul[1] was my solution for that, it was based on WebRender. I didn't get around to finish it in 2019, but I will work on it this year, maybe I'll get it to be mature enough to post it here.

> wide portability (at least Windoze, Linux, MacOS, iOS, Android, embedded: Azul is Windows-Linux-Mac only, don't underestimate the effort to properly port something to a new platform

> "though a Vulkan-based renderer can be made to run pretty much anywhere": WebRender is OpenGL + using software rendering as a fallback

> a permissive open source license: MPL-2.0

> a C interface/wrap to allow a wide programming language binding support: yes

> and an easily extensible and themable set of basic widgets: also yes

There is Iced which is used by system76 in Pop!_OS, Druid [DISCONTINUED], GTK-rs, Relm, Azul and Tauri. Personally I would use Tauri for its speed using the OS's native web render, documentation of use with things such as Sveltekit and the ability to make UI's using JS, CSS and HTML. Tauri similarly to Electron whilst being far faster. But its up to personal preference really. There aren't any solid "go to" options at the moment.

Sounds like you may be interested in azul not exactly servo based but on projects that originate from servo. Also this is not a typical WebView, for example it does not use HTML but uses DOM to define it's UI, and there is no JS engine in there.

Azul uses webrender. But your "glue" program is like half the web browser. You also need a vector graphics library to render websites. Webrender only does boxes, but not complex SVG paths. Once the plan was to use pathfinder, but mozilla fired the dev and they still using an old version of chromium's skia for that.

One day I'll get around to finish my library Azul [1]. Hopefully.
