QStandardPaths returning incorrent folder

[Momergil]

Hello!

I'm learning about the usage of the new Qt 5 class QStandardPaths by reading Qt Assistant, etc.. For curiosity, I decided to get the list of my computer's folders when I call QStandardPaths::standardLocations(StandartLocation ) to see what I got when, for my surprise, after asking for retrieving my downloads folder,

qDebug() << QStandardPaths::standardLocations(QStandardPaths::DownloadLocation);

qDebug() << QStandardPaths::standardLocations(QStandardPaths::DownloadLocation);

To copy to clipboard, switch view to plain text mode 

I received my documents folder ("C:/Users/Endrigo/Documents") instead of my actual downloads folder ("C:/Users/Endrigo/Downloads"). Isn't this a bug in this class? I called the functions multiple times and neither once the correct folder path was given (not forgetting that the result of standartLocations is a QStringList, so no problem if there were other options apart from it insofar "C:/Users/Endrigo/Downloads" was given).



Thanks,

Momergil

That will depend on what version of the ever moving target called Windows you are running. Before Vista no such location existed in the Windows special folders. Vista introduced a different function (SHGetKnownFolderPath(FOLDERID_Downloads)) reporting a different range of paths, including FOLDERID_Downloads. The Qt code uses the old method and returns the documents folder as a place you can download to that is available on Windows XP also.

There is a outstanding bug in work and code that you might adapt to find the location in the meantime.

Thanks for the answer, Chris. Thankfully I'm not actually in need for a correct implementation of that method, so I'll wait for further Qt releases.
