Re: MSVC gives warnings "qt_ui_utils.cpp(208, 25): warning C4996: 'QProcess::startDetached'"

From the online Qt docs
<https://doc.qt.io/qt-5/qprocess-obsolete.html#startDetached-2>: bool QProcess::startDetached(const QString <https://doc.qt.io/qt-5/qstring.html> &*command*) <https://doc.qt.io/qt-5/qprocess-obsolete.html#startDetached-2> This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code. Hence the MSVC warning, C4996 for a function that's marked as deprecated. According to the Qt docs you should be using the more extensive overload: bool QProcess::startDetached(const QString <https://doc.qt.io/qt-5/qstring.html> &*program*, const QStringList <https://doc.qt.io/qt-5/qstringlist.html> &*arguments*, const QString <https://doc.qt.io/qt-5/qstring.html> &*workingDirectory* = QString(), qint64 <https://doc.qt.io/qt-5/qtglobal.html#qint64-typedef> **pid* = nullptr) and you'll have to provide the arguments parameter, even if it's an empty QStringList.
