My Minimal ImGui Project

This project consits in creating a instant mode gui in C++ using Dear ImGui and ImPlot with SDL2 and OpenGL3 backend.

For now, the main file consited in displaying the demo proposed by the creator, build using cmake.

To create your own GUI, see in the main files the ImGui:ShowDemoWindow() and ImPlot:ShowDemoWindow() functions calls and the window created right after. Replace those calls with the call of a functions where you define windows. (Don't forget to modify CMakeLists.txt file if needed). You can find the examples provided of those two functions in the examples folder. These piece of code are a copy of demo from the Dear ImGui and ImPlot repo, but not builds, the build ones are those pulled during fetching of repos.

Dependancies

Dear ImGui and ImPlot are fetched and build during the compile process

Requier SDL2 and OpenGL3

sudo apt install libsdl2-dev # for SDL2

Alternatively if you want to build SDL2 inside the project, add those lines in the CMakeLists.txt

FetchContent_Declare(
  SDL2
  GIT_REPOSITORY "https://github.com/libsdl-org/SDL.git"
  GIT_TAG release-2.0.22
)

FetchContent_MakeAvailable(SDL2)

build

Inside the parent folder

mkdir -p build && cd build
cmake ..
cmake --build .

Launch executable
