Multiple Contexts

Is there a way for you to included the following native call methods like GetCurrentContext and SetCurrentContext?

    // Context creation and access
    // Each context create its own ImFontAtlas by default. You may instance one yourself and pass it to CreateContext() to share a font atlas between imgui contexts.
    // None of those functions is reliant on the current context.
    IMGUI_API ImGuiContext* CreateContext(ImFontAtlas* shared_font_atlas = NULL);
    IMGUI_API void          DestroyContext(ImGuiContext* ctx = NULL);   // NULL = destroy current context
    IMGUI_API ImGuiContext* **GetCurrentContext**();
    IMGUI_API void          **SetCurrentContext**(ImGuiContext* ctx);

I need to have the ability to support multiple contexts because I’m using multiple secondary buffers in Vulkan.

@perrymacmurray There is no solution, so you can implement it without any restrictions. At the moment I am more liberal about touching internal API, then before. I don’t think that anything else than context structs need to be done. I even think, that you can try to go with only basic code, which holds object pointer. No need to force yourself with implementing all struct fields etc. Only stuff you need to make things work. Just keep it clean, with general code style in mind.

Hi @SpaiR, sorry to revive a dead issue, but for my own code I was interested in switching between multiple contexts. Is there an existing way to do something like this, or is it still unimplemented?

If a solution doesn’t already exist, I’d love to give implementing context switching and maybe the internal API a shot, but I don’t completely understand what other than the contexts needs to be implemented. Do you have any advice?
