Can someone tell me how I can draw both OpenGL in the main window and the Dear ImGui windows at the same time so they both show up? Screenshots/Video. I've copied the ImImpl_RenderDrawLists() function and most of the InitImGui() function of the opengl example. I found that I need to add another line after line 41 As OpenGL ES is inspired by and a subset of OpenGL, its versions are roughly equal to a version of the OpenGL API. Compiled with Cmake Topics. Assuming that the ImGui is currently working on the application, So i am only sharing the codes of the part where the image is transferred to the screen. How do I scale the entire GUI? I need to support high DPI displays. While using the official wiki snippet code for rendering an image as a texture in imgui, I ran into the issue of the image being rendered as a I think the culprit is ImGui_ImplOpenGL3_Init(#version 310 es);, as I naturally assumed that this was the correct way to specify the version of OpenGL, but after reading this article, I believe I I am trying to run imgui on a Pi400 using SDL2 + OpenGLES3. rs › Rendering › Graphics APIs | GUI # opengl # opengl-rendering # opengl-context # renderer # imgui-rs # ui # sdl2 imgui-opengl-renderer An OpenGL renderer for imgui-rs. 10 specification.
