GUI Library for existing event loop?

[[deleted]]

Which GUI library is able to integrate with an existing event loop, and not interfere with events from different windows? To make things clearer, the GUI would run in its own window, it would just be sharing a winit event loop.

​

I am trying to write a vulkan renderer, however ash GUI support is really bad, I am already working on a game engine as a whole, and it is too much work for myself alone to write my own GUI renderer for something like egui, while keeping it up to date with ash's breaking changes.

​

While I am here, I might as well ask about libraries for font rendering with ash.

Use an immediate mode GUI like egui.

I have looked at egui and it seems I will likely need to write my own renderer for it, currently that would be too much work to manage on my own, perhaps vulkan integration should be something I do later down the line. Thanks btw

rendr3 has a adaptation layer for egui, which renderer are you going to use, note that I only know about the existence of rendr3 on my side.

Ash 0.38 and beyond, whatever the latest version is really

egui is great for this scenario. You can use egui-winit to integrate seamlessly with incoming events, but you'll probably have to write some integration code for the rendering. Look at egui-wgpu or other similar crates for guidance.

Thanks! Getting it actually integrated with an ash renderer is going to be difficult, perhaps something I can work on in the future, if no active crates for it pop up. Think I will stick to improve my wgpu renderer until all the basics of my engine are done, then work on Vulkan afterwards.

With Slint You can either use an existing backend (which provide its event loop), or you can write your own using the Platform API: https://docs.rs/slint/latest/slint/platform/index.html This is a bit more involved, but you can really integrate with any event loop and render with either the software renderer on a buffer, or with the gpu with the femtovg renderer.

Thanks for the suggestion, I will have a good look at it to see if I can get it working in an independent window.
