This enum describes the different locations that can be queried by
QDesktopServices::storageLocation and QDesktopServices::displayName.

\fn QString QDesktopServices::storageLocation(StandardLocation type)
\obsolete
Use QStandardPaths::writableLocation()
\note when porting QDesktopServices::DataLocation to QStandardPaths::DataLocation,
a different path will be returned.
\c{QDesktopServices::DataLocation} was \c{GenericDataLocation + "/data/organization/application"},
while QStandardPaths::DataLocation is \c{GenericDataLocation + "/organization/application"}.
Also note that \c{application} could be empty in Qt 4, if QCoreApplication::setApplicationName()
wasn't called, while in Qt 5 it defaults to the name of the executable.
Therefore, if you still need to access the Qt 4 path (for example for data migration to Qt 5), replace
\code
QDesktopServices::storageLocation(QDesktopServices::DataLocation)
\endcode
with
\code
QStandardPaths::writableLocation(QStandardPaths::GenericDataLocation) +
"/data/organization/application"
\endcode
(assuming an organization name and an application name were set).
