// dear imgui: wrappers for C++ standard library (STL) types (std::string, etc.)
|
|
|
|
// This is also an example of how you may wrap your own similar types.
|
|
// TL;DR; this is using the ImGuiInputTextFlags_CallbackResize facility,
|
|
// which also demonstrated in 'Dear ImGui Demo->Widgets->Text Input->Resize Callback'.
|
|
|
|
// Changelog:
|
|
// - v0.10: Initial version. Added InputText() / InputTextMultiline() calls with std::string
|
|
|
|
// Usage:
|
|
// {
|
|
// #include "misc/cpp/imgui_stdlib.h"
|
|
// #include "misc/cpp/imgui_stdlib.cpp" // <-- If you want to include implementation without messing with your project/build.
|
|
// [...]
|
|
// std::string my_string;
|
|
// ImGui::InputText("my string", &my_string);
|
|
// }
|
|
|
|
// See more C++ related extension (fmt, RAII, syntaxis sugar) on Wiki:
|
