How to use the backend with Vulkan window?

[nikitablack]

Hi. I'm using SFML in a Vulkan application, so my main window class is WindowBase. ImGui::SFML::Init accepts sf::Window or sf::RenderWindow, basically requiring OpenGL API. How to use it with WindowBase?

I did a quick replacement of sf::Window to sf::WindowBase and everything still compiles so maybe this is viable? I'll have to dig deeper on this later.

Ideally, ImGui-SFML should be separated into keyboard/event etc. part and allow you to use the renderer separately (Dear ImGui has OpenGL, Vulkan etc. backends). E.g. see how SDL backend for Dear ImGui doesn’t do any rendering.
I don’t have time to work on this, though. 😅
