Clear InputText box after pressing Enter about imgui

[cfillion]

Assuming you still want ImGui::GetIO().ConfigInputTextEnterKeepActive enabled: v1.90.2 added functions to imgui_internal.h for this:

myInput.clear();
if(ImGuiInputTextState* state { ImGui::GetInputTextState(ImGui::GetItemID()) })
  state->ReloadUserBufAndSelectAll();

In older versions InputText's internal buffer may still be cleared while active using ImGuiInputTextCallback.

static std::string myInput;
static bool clearBuffer;
ImGuiInputTextFlags flags { ImGuiInputTextFlags_EnterReturnsTrue | ImGuiInputTextFlags_EscapeClearsAll };
ImGuiInputTextCallback callback {};
if(clearBuffer) {
  callback = [](ImGuiInputTextCallbackData *data) { data->DeleteChars(0, data->BufTextLen); return 0; };
  flags |= ImGuiInputTextFlags_CallbackAlways;
  clearBuffer = false;
}
if(ImGui::InputText("Input", &myInput, flags, callback)) {
  myInput.clear();
  clearBuffer = true;
}

That was exactly what I was looking! Thank you for the help!
