imgui VS NanoGUI

Currently, I have narrowed potential libraries to: 1. Flutter 2. FLTK 3. Relm (GTK) 4. iced 5. Slint 6. Imgui, Imgui-rs 7. and gtk-rs

Imgui, Imgui-rs

Dear ImGui easy to use and understand immediate mode is simple to understand and fits games with a render loop Small file size Con: Doesn't look like your native OS widgets

- X Toolkit Intrinsics Reference Manual

However they have very little to do with how modern operating systems (Windows, MacOS) deal with that stuff.

As for toys, I'd recommend reading about Dear ImGui [1]. It handles everything you mentioned while being self-contained so you can see how everything works from top to bottom. Many talks and articles have been written about it though I can't vouch for any of them.

ImGUI (https://github.com/ocornut/imgui) probably as simple as it can get

One simple, rather unimportant GUI library is this one, and even they claim a pretty long user list

Dear ImGui and SFGUI are options.

Raylib was created primarily for game development. If all you need is a minimal graphics library for drawing ui, then I would check out Nuklear or IMGUI Raylib will not help all that much with writing code to interface with the arduino and calculate the map.

With 2.5 days you probably don't want anything that requires much setup, so Qt is probably a non-starter. You could try this one: https://github.com/wjakob/nanogui, the examples are not the platonic ideal of modern C++ programming, but that also means you don't need much mastery of the language to hammer a program until it has a GUI.

I've dipped my toes into GUI development just enough to know you can have "simple," or you can have "native," but not both. There are smaller projects like nanogui[0] and microgui[1] out there, but of course they're only as small as they are because they don't use native widgets.

### [NanoGUI](https://github.com/wjakob/nanogui)

I have only played with this briefly, but after the initial setup NanoGUI seemed pretty intuitive https://github.com/wjakob/nanogui

Wondering if this was inspired by Wenzel Jakob's nanogui [0] by any chance. (cz that's what I wanted to do, rewrite nanogui in C, so I don't have to rely on a C++ compiler).
