Set file owner:group in Linux using Qt/C++

Question

I need to change the owner and group of a file under Linux using Qt 5.7 /C++. I found the QFileInfo::ownerID and QFileInfo::groupID getters, but there appear to be no setters for these values.

I need the Qt equivalent of chown.

Is there a way to set these values using Qt functions?

I was hoping to use a native Qt function, otherwise chown from C/C++ is next best thing. Using QProcess seems like a lot of overhead and doesn't really answer the question. — TSG, Jan 19 '17 at 05:42

Setting file permissions can be done by QFile::setPermissions method instead of using native chmod function, but Qt has not equivalent of chown. You should use chown() function from unistd.h Look here.

I wasn't looking for file permissions, just ownership. But accepted the answer for the second part of the question. – TSG Jan 19 '17 at 15:33
