Imgui source files within egui library code

HOW TO SWITCH TO A NEW IMGUI VERSION: Imgui source code is downloaded as /coderoot/bluetree/egui/dependencies/downloads/imgui/imgui-1.92.6-docking. Selected imgui source code files are copied into egui project.

  • Copy source files from /coderoot/bluetree/egui/dependencies/downloads/imgui/imgui-1.92.6-docking directory into /coderoot/bluetree/egui/code/imgui directory.

  • For version imgui-1.92.6-docking these files are imconfig.h, imgui.cpp, imgui.h, imgui_demo.cpp, imgui_draw.cpp, imgui_internal.h, imgui_tables.cpp, imgui_widgets.cpp, imstb_rectpack.h, imstb_textedit.h and imstb_truetype.h. File list and location has been consistent between diggerent imgui versions.

  • Copy GLF/Opengl implementation files from /coderoot/bluetree/egui/dependencies/downloads/imgui/imgui-1.92.6-docking/backends to /coderoot/bluetree/egui/glfw_opengl3/imgui. These files are imgui_impl_glfw.cpp, imgui_impl_glfw.h, imgui_impl_opengl3.cpp, imgui_impl_opengl3.h and imgui_impl_opengl3_loader.h.

  • Some problem with egui, assert for table fails. I needed to comment an assert away to be able to run. The assert is in file imgui.cpp, line 3429. Marked with string “PEKKA, I HAVE SOME ERROR HERE”.
