Trying to get a 3 part rendering pipeline working but events aren't processed. about imgui HOT 3 CLOSED

Thanks for the information.

I think I've got a more appropriate way to get what I want. I can use the SDL renderer to render to a SDL_Texture, then use ImGui as I want using and imgui::image to add the SDL rendered texture mid gui.

thanks you.

Why are you trying to do that? It doesn’t seem to make sense. We cannot help you find the right solution without understanding the context.

You would either want to use a single imgui context with possibly manual rendering of some dimming layer, or use two imgui contexts. But you certainly cannot use a single imgui context for two unrelated pieces of contents.

Just to elaborate a bit on why your approach doesn't and cannot work...

You are submitting and rendering two frames per loop, alternating between windows. Inputs are processed between frames. For some operations, ImGui needs to take a look at what was where on the screen during the last frame submitted, then an appropriate action can be triggered when the same item is again submitted the next frame. Since you are alternating, you have no single window or widget that is present in both the current and the previous frame, therefore interaction can't work properly.
