Incorrect link to Qt typedef inside '@' code.

Found it from this "post":https://qt-project.org/forums/viewthread/41988/#174218

In the code surrounded by '@'
@
QFileInfoList drives = QDir::drives();
@

QFileInfoList gets translated to http://qt-project.org/doc/qt-5/QFileInfoList.html but it should be http://qt-project.org/doc/qt-5/qfileinfo.html#QFileInfoList-typedef

Hmm... I think the best fix for this would be for the official documentation builder to spit out a map of classes/typedefs-to-URLs that this site can use. It's not sustainable to manually write exceptions each time new API is released.
