QT 通过QTextStream 实现 输入回车

QFile file("userinfo.ini");
file.open(QIODevice::Text | QIODevice::WriteOnly);
QTextStream out(&file);
out << "[info]"
<< endl << "id="    //其中  endl 就是回车
<< endl << "ycode="
<< endl << "ip="
<< endl << "cli_ver=1.0"
<< endl << "ser_ver="
<< endl << "plugin="
<< endl <<"up_date=";
file.close();
