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This function is obsolete.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.
