Elements C++ GUI library VS sciter

There's a relatively new C++ GUI library literally called "Elements". Not sure how it works though, but the way it looks, and the music background of its creator makes it appear designed for DAWs.

Further, if you we want a "modern" C++ GUI framework what actually would be modern would be to use mechanisms in the language itself as a quasi-DSL from within the language. This is something like what Joel de Guzman is doing with Elements

It's a complex domain. The closest we have at the moment is Elements which hasn't been proposed for Boost (yet?) but is by Joel de Guzman, the primary author of Boost.Spirit.

I ended up with elements gui https://github.com/cycfi/elements

If you don't want to use Qt I honestly think your best bet may be to become an early adopter of cycfi elements depending on your project. Elements is still rough but is useable for small applications. I think when it is finished it will be the best choice for a retained mode GUI library, but right now it is missing a lot of things (e.g. the standard common dialogs, "open", "Save as", etc.) , and has basically zero documentation.

For the past year we were evaluating EFL, QML and Flutter for our embedded TV devices after having used the first two for last 5+ years and choice was made to go with Flutter. Performance is great, license is great, and development experience, judged by the whole development team, is the best. Hence my remark on being sad as QML could have had a great future, even transitioned to modern C++ without need for separate language, if there was a huge adoption and proper choices made by the company, e.g. see https://github.com/cycfi/elements.

There's another project called Sciter that uses CSS to target native graphics libraries: https://sciter.com

It was hard, but the biggest barrier is the obscurity of the knowledge.

Text layout is the hardest, because working with glyphs and iterating them in reverse for RTL is brain-breaking. And line wrapping gets really complicated. It's also the most obscure because nobody has written down everything you need to know in one place. After I finished block layout early on, I had to stop for a couple of years (only working a few hours a week though) and learn all of the ins, outs, dos, and don'ts around shaping and itemizing text. A lot of that I learned by reading Pango's [1] source code, and a lot I pieced together from Google searches.

But other than that, the W3C specifications cover almost everything. The CSS2 standard [2] is one of the most beautiful things I've ever read. It's internally consistent, concise, and obviously the result of years of deliberation, trial and error. (CSS3 is great, but CSS2 is the bedrock for everything).

otherwise, if we have only retained mode as in browsers, we will need to modify the DOM heavily and create temporary elements for handles.

I've still never used it but I've long been curious about Sciter:

https://sciter.com

These bullet points are exactly what I did in Sciter (https://sciter.com)

- Windowing

-- Tabs

-- Menus

-- Painting

-- Animation

-- Text

-The compositor

-Handling input

-- Pointer input

-- Keyboard input

- Accessibility

- Internationalization and localization

- Cross-platform APIs

- The web view

- Native look and feel

On top of that DOM and CSS implementations to achieve declarative UI. And JS as a languuage behind UI - declarative in some sense way of defining UI behavior.

I'm not sure if it can support all the libraries but yes it can be used to make desktop apps. Theres also Sciter.
