| 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. |
