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/

Missing one of the best choices as long as "maturity" isn't on the top of your list: Bevy - https://bevyengine.org/

Game engine written in Rust, leveraging ECS in almost every place and way, with a really capable WASM export option. Wrestling ECS for the first time might take you some time, but in my experience helps you keep game code as clean and decoupled as game code could be.

I don't see WASM/WebGPU changing anything when it comes to gaming, as an industry, personally. 3d visualizations and interactive websites? Yeah definitely a nice improvement over WebGL 2, if years late.

WebGPU is pretty far behind what AAA games are using even as of 6 years ago. There's extra overhead and security in the WebGPU spec that AAA games do not want. Browsers do not lend themselves to downloading 300gb of assets.

Additionally, indie devs aren't using Steam for the technical capabilities. It's purely about marketshare. Video games are a highly saturated market. The users are all on Steam, getting their recommendations from Steam, and buying games in Steam sales. Hence all the indie developers publish to Steam. I don't see a web browser being appealing as a platform, because there's no way for developers to advertise to users.

That's also only indie games. AAA games use their own launchers, because they don't _need_ the discoverability from being on Steam. So they don't, and avoid the fees. If anything users _want_ the Steam monopoly, because they like the platform, and hate the walled garden launchers from AAA companies.

(I work on high end rendering features for the Bevy game engine https://bevyengine.org, and have extensive experience with WebGPU)

I was working through an example in the repo for the Bevy game engine recently and came across this code

That's possible. I did spend quite a bit of time tinkering with compiler flags, and followed the recommendations.

Some notes I found just now seems to agree with my results, though: https://github.com/bevyengine/bevy/issues/3978#issuecomment-...

I cannot recommend immediate mode GUI programming based on the limitations I've experienced working with egui.

egui does not support putting two widgets in the center of the screen: https://github.com/emilk/egui/issues/3211

It's really easy to get started with immediate mode, it's really easy to bust out some UI, but the second you start trying to involve dynamically resized context and responsive layouts -- abandon all hope. The fact it has to calculate everything in a single pass makes these things hard/impossible.

... that said, I'm still using it for https://ant.care/ (https://github.com/MeoMix/symbiants) because it's the best thing I've found. I'm crossing my fingers that Bevy's UI story (or Kayak https://github.com/StarArawn/kayak_ui) become significantly more fleshed out sooner rather than later. Bevy 0.13 should have lots more in this area though (https://github.com/bevyengine/bevy/discussions/9538)

I've also been enjoying building My First Game™ in Bevy using ECS. The community around Bevy really shines, but Flecs (https://github.com/SanderMertens/flecs) is arguably a more mature, open-source ECS implementation. You don't get to write in Rust, though, which makes it less cool in my book :)

I'm not very proud of the code I've written because I've found writing a game to be much more confusing than building websites + backends, but, as the author notes, it certainly feels more elegant than OOP or globals given the context.

I'm building for WASM and Bevy's parallelism isn't supported in that context (yet? https://github.com/bevyengine/bevy/issues/4078), so the performance wins are just so-so. Sharing a thread with UI rendering suuucks.

If anyone wants to browse some code or ask questions, feel free! https://github.com/MeoMix/symbiants

These days, some game engines have done pretty well at making compute shaders easy to use (such as Bevy [1] -- disclaimer, I contribute to that engine). But telling the scientific/financial/etc. community that they need to run their code inside a game engine to get a decent experience is a hard sell. It's not a great situation compared to how easy it is on NVIDIA's stack.
