gtk4-cross VS Slint

I use it from rust, it works with libadwaita. Since it's rust I just run cargo in a docker container. https://github.com/MGlolenstine/gtk4-cross

(Assuming GTK4) For Windows you could try gtk4-cross. It was pretty clunky to use for Vala but since they have a Rust-specific image it should be easier for your use case

For gtk programs I just put the dll's in the same folder as the binary and distribute it as a zip. Not the most elegant, but it works. I use this docker image to do the bundling https://github.com/MGlolenstine/gtk4-cross

If you're willing to install docker it's really easy to build and package for windows. https://github.com/MGlolenstine/gtk4-cross

I'm guessing you're not using this Docker container? → https://github.com/MGlolenstine/gtk4-cross

You can just bundle the required DLL's in the same directory as the executable. They don't need to install anything. You can use this docker container to handle the bundling automatically for you https://github.com/MGlolenstine/gtk4-cross

With gtk4 you can just bundle the libs. You can check out https://github.com/MGlolenstine/gtk4-cross for a docker container that handles cross-compiling to windows and packaging the libs.

The image for cross compiling: gtk4-cross

Yeah, it's actually much easier to cross compile from linux to windows. If you only have windows you can use docker desktop and this container to cross compile https://hub.docker.com/r/etrombly/rust-crosscompile . It doesn't have gtk4 support yet though, someone forked it if you need gtk4 https://github.com/MGlolenstine/gtk4-cross

As an anecdote, the three top contributors to sixtyfps are ex-Qt people. I think it is not anecdotal that there is at least some degree of overlap and competition between Rust and C++, and that this is a market that surely The Qt Company is watching.

SixtyFPS (https://sixtyfps.io/) is in progress for Rust, but it is still early days. It also does not technically use a native toolkit (it uses Qt), but I believe that might be on roadmap. For traditional GUI apps, I think the lack of a table or tree widget is the most limiting for the time being. They have stated they intend to remedy that.

The most promising GUI hasn't been posted here, SixtyFPS. It's in it's early stages and not FOSS, but it's built by some ex-QT cats and has a lot of potential.

People have been recommending https://sixtyfps.io/ to me.

There is already a project to make a Qt like GUI toolkit in Rust: https://sixtyfps.io/ It is really similar to Qt https://sixtyfps.io/releases/0.1.5/docs/rust/sixtyfps/index.html

People are doing that too. https://sixtyfps.io/ is basically a Qt clone in Rust, actually developed by previous Qt developers.

spdlog, a pretty useful and more and more commonly used logging library for C++.\ SixtyFPS, an emerging GUI library for Rust, but you can use it in multiple languages. It uses OpenGL or Qt currently as backend (well, it's a new library and they wanted two from the get-go to make sure their abstractions are done right/well enough). They started a company this year for it too.

Just so some are not aware, there's a new project called sixtyfps by some people who were in the Qt world for long. I didn't take a deep dive into it but it looks promising.
