My Issue/Question:

As per issue 4761, SetKeyboardFocusHere looks like it doesn't work correctly with InputTextMultiline:

static char buffer[16];
bool reclaim_focus {false};
const auto flags {ImGuiInputTextFlags_CtrlEnterForNewLine | ImGuiInputTextFlags_EnterReturnsTrue};

if (ImGui::InputTextMultiline("##", buffer, sizeof(buffer), {}, flags)) {
    reclaim_focus = true;
}

if (reclaim_focus) {
    ImGui::SetKeyboardFocusHere(-1);
}

Pressing enter still makes the input text box loose focus.

But with InputText it works:

static char buffer[16];
bool reclaim_focus {false};
const auto flags {ImGuiInputTextFlags_CtrlEnterForNewLine | ImGuiInputTextFlags_EnterReturnsTrue};

if (ImGui::InputText("##", buffer, sizeof(buffer), flags)) {
    reclaim_focus = true;
}

if (reclaim_focus) {
    ImGui::SetKeyboardFocusHere(-1);
}

It looks like resetting the focus every frame works (sets the focus), but it's undesirable:

static char buffer[16];
const auto flags {ImGuiInputTextFlags_CtrlEnterForNewLine | ImGuiInputTextFlags_EnterReturnsTrue};

ImGui::InputTextMultiline("##", buffer, sizeof(buffer), flags);

ImGui::SetKeyboardFocusHere(-1);
