1//----------------------------------------------------------------------------- 2// COMPILE-TIME OPTIONS FOR DEAR IMGUI 3// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure. 4// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions. 5//----------------------------------------------------------------------------- 6// A) You may edit imconfig.h (and not overwrite it when updating imgui, or maintain a patch/branch with your modifications to imconfig.h) 7// B) or add configuration directives in your own file and compile with #define IMGUI_USER_CONFIG "myfilename.h" 8// If you do so you need to make sure that configuration settings are defined consistently _everywhere_ dear imgui is used, which include 9// the imgui*.cpp files but also _any_ of your code that uses imgui. This is because some compile-time options have an affect on data structures. 10// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts. 11// Call IMGUI_CHECKVERSION() from your .cpp files to verify that the data structures your files are using are matching the ones imgui.cpp is using. 12//----------------------------------------------------------------------------- 13 14#pragma once 15 16// Have each embedded of ImGui define this symbol : 17struct ImGuiContext; 18extern thread_local ImGuiContext* __MesaImGui; 19#define GImGui __MesaImGui 20 21//---- Define assertion handler.
