Code⇄GUI bidirectional editing via LSP
I use the the code lenses of code action feature of the LSP so that the user can start a preview. The LSP server will then open a native window on desktop.
Every time the users do some change in the code, the editor sends the document and we re-render the preview.
I use the textDocument/documentHighlight request to know when elements are being selected from the code so I can highlight them in the preview.
When selecting an element in the preview UI, my LSP server sends a window/showDocument to position the cursor at the right location. And if the user changes property or do change in the file, we do a workspace/applyEdit command with the changes.
Btw, the code is there: https://github.com/slint-ui/slint/tree/master/tools/lsp

I Switched from Flutter and Rust to Rust and Egui
I think Slint is getting pretty close to that these days: https://slint.dev/
No quick and easy drag&drop just yet, but IDE support for live preview rendering makes it come pretty close. I do long for the Visual Studio GUI design days, but things aren't as barebones anymore as they used to be in open source Rust land.

Qt's New Bridging Technology – Looking Back to Move Forward
I actually wrote Rust bindings for Qt a while back: https://github.com/woboq/qmetaobject-rs/. I'm curious to see how Qt's own take with Qt Bridges will work out. That said, I’ve since moved on and now work on Slint [https://github.com/slint-ui/slint]
Slint was created with the same idea as what drives "Qt Bridges". We made a UI toolkit that is language-agnostic from the start. Slint uses its own UI language (inspired by QML), and gives you first-class, idiomatic APIs in Rust, C++, Pyhton, and JavaScript. And a clean separation between UI and business logic.

Show HN: Brisk – Cross-Platform C++ GUI Framework: Declarative, Reactive, Fast
While I welcome new cross-platform GUI Frameworks, I wonder why not use a declarative UI similar to QML? Even Slint[1] (which is built in Rust) uses such syntax for its UI.

Electrobun: Cross-platform desktop applications written in TypeScript
If you want to use Rust, Slint[0] may be something to consider, seeing as the existing bindings for Qt and QML are not very pleasing to use (mostly talking about qmetaobject-rs and cxx-qt). If I'm not mistaken, Slint is developed by ex-QML people.

LSP: The Good, the Bad, and the Ugly
I've implemented a LSP server (for Slint - https://slint.dev) and I agree with this article.
The paradox is that it was meant to avoid to write language support for each editor. Yet, if you want to support vscode you must create a specific extension for it and can't just have a language client.
The article mention the configuration problem, but I'd add the problem that Microsoft refuses to specify a way for the server to tell the client what are the config options so that the client can show some kind UI showing the possible configuration options with a description of what they do. https://github.com/microsoft/language-server-protocol/issues...

Review ★★★★★ 9/10
Slint is a great UI framework, easy to get started with and quick to iterate on UI with the excellent live preview and LSP integrated into VS Code. The main downside in my opinion is the somewhat long compile times once you have a lot of UI code, which I hope they will be able to improve upon.
