Qt - How to get the "Temp" dir for an arbitrary user?

For each OS there is a location for storing temporary data. It could be like: C:/Users/[user name]/AppData/Temp (or so). How ca开发者_高级运维n I get this path independently from OS with QT?

It is not possible to get the temp directory for an arbitrary user, but for the current user you can use QDir::temp() or QDir::tempPath().

You want to get QDesktopServices::TempLocation. See http://doc.trolltech.com/qtextended4.4/qdesktopservices.html#StandardLocation-enum for details.

In Qt 5, you can use QStandardPaths::writableLocation(QStandardPaths::TempLocation) to get the temporary directory path as a QString. You'll need to #include <QStandardPaths> to do so.
