  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. //-----------------------------------------------------------------------------

  18. //#define IM_ASSERT(_EXPR) ((void)(_EXPR)) // Disable asserts
  19. //---- Define attributes of all API symbols declarations, e.g. for DLL under Windows
  20. // 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.
  21. // - Windows DLL users: heaps and globals are not shared across DLL boundaries! You will need to call SetCurrentContext() + SetAllocatorFunctions()
  22. // for each static/DLL boundary you are calling from. Read "Context and Memory Allocators" section of imgui.cpp for more details.

  43. //#define IMGUI_DISABLE_DEFAULT_FILE_FUNCTIONS // Don't implement ImFileOpen/ImFileClose/ImFileRead/ImFileWrite and ImFileHandle so you can implement them yourself if you don't want to link with fopen/fclose/fread/fwrite. This will also disable the LogToTTY() function.
  44. //#define IMGUI_DISABLE_DEFAULT_ALLOCATORS // Don't implement default allocators calling malloc()/free() to avoid linking with them. You will need to call ImGui::SetAllocatorFunctions().
