// COMPILE-TIME OPTIONS FOR DEAR IMGUI
|
|
// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
|
|
// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
|
|
//-----------------------------------------------------------------------------
|
|
// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/branch with your modifications to imconfig.h)
|
|
// B) or add configuration directives in your own file and compile with #define IMGUI_USER_CONFIG "myfilename.h"
|
|
// If you do so you need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include
|
|
// the imgui*.cpp files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
|
|
// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
|
|
// 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.
|
