Do you know Slint?

I haven't really used it, but it seems to use the same idea, except it's native to Rust but comes with its own C++ and JavaScript bindings. I believe the project was started by some folks that left Qt (or some company that held the IPR at some point..).

I've checked it out and it's on my list of things to revisit in the future, but I've been burned in the past by using less-proven GUI frameworks, which is why I'm trying to stick with something like QML.

It's definitely something that looks promising, though. Hope to replace Qt with it in the future if it works out.
