gtk4-rs VS Slint

The only example that shedded some light on the integration was gtk4 + femtovg. So I mimicked the example, using gtk4-rs and Skia's rust bindings. I had some code similar to the following inside a subclass of GLArea to setup Skia's DirectContext, but it failed:

Hi, I am studying gtk4 with rust, now trying to check examples from https://github.com/gtk-rs/gtk4-rs/tree/master/examples some of them are building and compiling but text_viewer(cargo run --bin text_viewer) and some others are failing with the error below

I created a demo of using column view in gtk4-rs rust here...maybe be a point of reference https://github.com/gtk-rs/gtk4-rs/tree/master/examples/column_view_datagrid

To build the UI, I used gtk-rs. My experience with this library was quite pleasant; it was easy to use and there were a lot of examples. However, it isn't as widely used as, say, React, so it was difficult to find answer on Stack Overflow (I come from a JavaScript/Typescript background).

There are good GTK bindings for Rust (https://github.com/gtk-rs/gtk4-rs and https://github.com/Relm4/Relm4)

I've been following this example to get something that works for whatever the default opengl context version is, however, I can't figure out how to request a specific opengl version on context creation: https://github.com/gtk-rs/gtk4-rs/tree/master/examples/glium_gl_area

gtk4-rs itself feels like it takes very little time to build: https://github.com/gtk-rs/gtk4-rs but when you add up all the time to building all examples afterwards, it's about the same and provides the equivalent of capabilities of QT(C++ and RUST) so yes it's going to take time to build.

The gtk-rs project provides safe Rust bindings for GNOME stack-based libraries, like the GTK 3 and GTK 4 libraries. The gtk3-rs and gtk4-rs libraries provides GTK 3 and GTK 4 functionalities, respectively.

Check out the examples in the gtk4-rs repository.

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.
