1 //----------------------------------------------------------------------------- 2 // DEAR IMGUI COMPILE-TIME OPTIONS 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 Dear ImGui, or maintain a patch/rebased branch with your modifications to it) 7 // B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template. 8 //----------------------------------------------------------------------------- 9 // You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp 10 // files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures. 11 // Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts. 12 // Call IMGUI_CHECKVERSION() from your .cpp file to verify that the data structures your files are using are matching the ones imgui.cpp is using. 13 //----------------------------------------------------------------------------- 14 15 #pragma once 16 17 //---- Define assertion handler. Defaults to calling assert(). 18 // If your macro uses multiple statements, make sure is enclosed in a 'do { .. } while (0)' block so it can be used as a single statement. 19 //#define IM_ASSERT(_EXPR) MyAssert(_EXPR) 20 //#define IM_ASSERT(_EXPR) ((void)(_EXPR)) // Disable asserts 21 22 //---- Define attributes of all API symbols declarations, e.g. for DLL under Windows 23 // Using Dear ImGui via a shared library is not recommended, because of function call overhead and because we don't guarantee backward nor forward ABI compatibility. 24 // - Windows DLL users: heaps and globals are not shared across DLL boundaries! You will need to call SetCurrentContext() + SetAllocatorFunctions() 25 // for each static/DLL boundary you are calling from.
