Simple DEMO of rendering GLFW window inside imgui window

[Yuchenhenry]

Hello! I am a new learner on the Dear ImGUI. Recently I am working on a simple application with GLFW. Trying to see if there is a simple DEMO of how to render the GLFW window inside the ImGUI window. I want to have a scene window to present the model while a control window for detailed properties for GLFW functions. Any thoughts are welcome!

Thank you very much!

You cannot render a "GLFW window" inside another thing, it's not a meaningful question or statement as GLFW deals with native/platform windows (e.g. MS-Windows windows).

What you maybe mean is trying to render the output of your OpenGL rendering in a Dear ImGui window.
For this you will need to render your OpenGL scene into a texture. There are many OpenGL tutorials to do that and it has nothing to do with GLFW nor with Dear ImGui, e.g.

Once you have an OpenGL texture with your scene you can render it in an Dear ImGui window with ImGui::Image() just like you would with a static image: https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples
