Nuklear VS Photon Micro GUI

You might want to try Nuklear https://github.com/vurtun/nuklear or imgui https://github.com/ocornut/imgui , both to my knowledge have a Vulkan backend. Source: over 1 year ago

In fact, if using a modern graphics pipeline with shaders, you will actually have to learn how to draw a single rectangle to your screen, and then use that knowledge to draw (anti-aliased) lines, rectangles, arcs, circles, ellipses, etc. too. For instance, have a look at https://www.cairographics.org/ https://github.com/vurtun/nuklear https://github.com/memononen/nanovg and https://github.com/nical/lyon. There are...

Another option that's pure c and a great library is nuklear https://github.com/vurtun/nuklear. Source: over 2 years ago

If you need the GUI system, then you will be binding against Java and it will be very time consuming. You might be better off looking at some of the young wxWidgets / Qt Android ports. Or simply using a light OpenGL based UI library like Nuklear (or newer). Source: almost 3 years ago

P.S.: I know Nuklear has got a node editor, but this editor is only in an early stage of development and Nuklear development has pretty much halted since Vurtun left. Source: almost 3 years ago

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. https://github.com/cycfi/elements. - Source: Hacker News / 12 months ago

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. Source: about 1 year ago

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. Source: over 1 year ago

Elements was mentioned as a specific example of an MIT-licensed GUI library on the CPPcast episode from 5 May 2022. Source: almost 2 years ago

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...
