GLFW Callbacks after ImGui initialization #4981
Description
Version/Branch of Dear ImGui:
Version: 1.87 WIP (18608)
Branch: docking
Back-end/Renderer/Compiler/OS
Back-ends: imgui_impl_glfw.cpp + imgui_impl_opengl3.cpp
My Issue/Question:
How are custom callbacks supposed to be set with GLFW post ImGui initialization? I would prefer to allow ImGui to install it's callbacks and not have to worry about calling them in my own code, which seems to be supported outside of this case.
Screenshots/Video
None
Standalone, minimal, complete and verifiable example:
int main () {
// Window Creation... etc...
glfwSetKeyCallback(window, my_key_callback);
ImGui::CreateContext();
ImGuiIO& io = ImGui::GetIO();
io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard;
ImGui_ImplGlfw_InitForOpenGL(window, true);
// At this point, ImGui_ImplGlfw_GetBackendData()->PrevUserCallbackKey is my_key_callback
ImGui_ImplOpenGL3_Init("#version 450");
glfwSetKeyCallback(window, my_new_key_callback);
// How to set state so that GLFW key callback is ImGui's, and
// ImGui_ImplGlfw_GetBackendData()->PrevUserCallbackKey is my_key_callback?
