Wireshark · Wireshark-dev: Re: [Wireshark-dev] MSVC gives warnings "qt_ui_utils.cpp(208, 25): warning C4996: 'QProcess::startDe

[Roland Knall <rknall@xxxxxxxxx>]

Which was used in the past, but that function has other issues (opening the users documents if the trace file path contains spaces)

I am looking into it. Empty StringList seems to solve it, but had not been able to test it properly yet

Cheers

From the online Qt docs:

bool QProcess::startDetached(const QString &command)

This function is obsolete.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 &program, const QStringList &arguments, const QString &workingDirectory = QString(), qint64 *pid = nullptr)

and you'll have to provide the arguments parameter, even if it's an empty QStringList.
