возможна ли графика в stringstream?

Имею функцию в Qt

void ob_panel::GetOb_PanelDate(int day, int month, int year, int hour, int minute, int seconds){
    std::stringstream output;
    output << day << ":" << month << ":" << year << "\n";
    output << hour << ":" << minute << ":" << seconds << "\n\n";
    output << "Höhe: Baro" << "\n";
    output << "DL: \t" << "\n";
    output << "GPS: " << "\n";
    output << "DVC recorder time" << "\n\n";
    output << "Video - Mitte" << "\n";
    output << "Ost: " << "\n";
    output << "Nord: " << "\n";
    output << "Grund " << std::endl;
    ui->pTE_Verbindung->setPlainText(output.str().c_str());
}

Хотел бы в поле output << "GPS: " << "\n"; вывести графику как на скриншоте
