lvgl VS imgui

lvgl

LVGL (https://lvgl.io/) - MIT

2) if you're running it on an embedded device with limited memory then i'd suggest lvgl (https://github.com/lvgl/lvgl)

I've had good luck with LGVL.

If Qt licensing turns out to be unreasonable for you either way, there are a few other graphical toolkit options. One of my favorites is LVGL. That one might be closer to what you're used to in the microcontroller C space; very very light on resources, but could be a lot more work to develop (unless you're just so used to C that you pick it up naturally). Running it on Linux is a lot easier than on a microcontroller since you can use SDL or write direct to the framebuffer. LVGL UIs can also be prototyped fairly easily in a web browser playground.

LVGL. It is designed for embedded system, but can be used on virtually every platforms.

Good C library list: https://en.cppreference.com/w/c/links/libs https://github.com/Immediate-Mode-UI/Nuklear + C89, no dependencies, public license. 5/5 https://www.tecgraf.puc-rio.br/iup/ + good tutorial and wiki guides 5/5 https://libsdl.org/ + infinite possibilities - whole library for making games, forums, wiki - complicated, not many C tutorials, need to manage game states... 4/5 https://github.com/lvgl/lvgl + good docs - for embedded systems 4/5 https://github.com/ocornut/imgui + Popular, inspired Nuklear - for C++ 3/5 https://docs.enlightenment.org/api/imlib2/html/ + very efficient, used in Conky - uses X so only for Linux, just for displaying images and text and stuff 2/5 https://github.com/rxi/microui + simple, small - you need to handle your own drawing 2/5 GTK+ - no

So RT-Thread IoT OS partnered with LVGL, STMicroelectronics, Nuvoton, and NXP to bring this contest, opening an opportunity for embedded developers that come from everywhere to explore more possibilities with embedded GUI.

I actually ran across this and thought it would be fun to play around with https://github.com/lvgl/lvgl

If your program doesn't need to conserve power, you can use Dear ImGUI, it's very easy to use and can run through most rendering APIs or graphic libraries. The Cherno on YouTube has some good videos on it to kickstart you

I'm not sure if this is what you're looking for, but Dear ImGUI is kind of a gold standard within the AAA game development industry. It's MIT licensed and u/ocornut is one of the most helpful and coolest dudes in the open source world.

Take a look at dear imgui, https://github.com/ocornut/imgui.

C++ devs there is also bloat-free 'Dear ImGUI', nice for simple but also interesting user interfaces. https://github.com/ocornut/imgui

Not a 'native' feel and not for everybody, but a pleasure to use, in my opinion.

Imgui (https://github.com/ocornut/imgui) has always been my go to for this sort of thing. Its cross platform and pretty easy to get your head around, especially if you're not a UI kind of person.

https://github.com/ocornut/imgui - here you go ^.^, dear-imgui.

The only thing I could really think of is something like ImGui for C# (https://github.com/mellinoe/ImGui.NET) but I've never used it. It's going to give you some simple wrappers around ImGui (https://github.com/ocornut/imgui) but even this is going to lock you into the UI framework -- you can't just "draw a rectangle" per se and use it as a "control." Do note however this is an "immediate mode" GUI which is different from how most general desktop windowing systems work in "retained mode" (which are typically event driven, which saves on computing power to not draw the same stuff over and over).

So I just watched a video by The Cherno which he talked about ImGui and how to install it so I followed along copied the docking git repository then went into my folder examples and opened the imgui_examples.sln file and chose the example_glfw_vulkan option and opened source/main.cpp and there is our problem. When I opened it under line 20 "#include " there is a red line and it says "Cannot open source file "vulkan/vulkan.h". Does anyone have a solution or should I switch to the other options like opengl3/directx12 etc.
