| 1 | // dear imgui: wrappers for C++ standard library (STL) types (std::string, etc.) |
| 2 | |
| 3 | // This is also an example of how you may wrap your own similar types. |
| 4 | // TL;DR; this is using the ImGuiInputTextFlags_CallbackResize facility, |
| 5 | // which also demonstrated in 'Dear ImGui Demo->Widgets->Text Input->Resize Callback'. |
| 6 | |
| 7 | // Changelog: |
| 8 | // - v0.10: Initial version. Added InputText() / InputTextMultiline() calls with std::string |
| 9 | |
| 10 | // Usage: |
| 11 | // { |
| 12 | // #include "misc/cpp/imgui_stdlib.h" |
| 13 | // #include "misc/cpp/imgui_stdlib.cpp" // <-- If you want to include implementation without messing with your project/build. |
| 14 | // [...] |
| 15 | // std::string my_string; |
| 16 | // ImGui::InputText("my string", &my_string); |
| 17 | // } |
