enum QDesktopServices::StandardLocation

Use QStandardPaths::StandardLocation (see storageLocation() for porting notes)

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

Constant	Value	Description
`QDesktopServices::DesktopLocation`	`0`	Returns the user's desktop directory.
`QDesktopServices::DocumentsLocation`	`1`	Returns the user's document.
`QDesktopServices::FontsLocation`	`2`	Returns the user's fonts.
`QDesktopServices::ApplicationsLocation`	`3`	Returns the user's applications.
`QDesktopServices::MusicLocation`	`4`	Returns the users music.
`QDesktopServices::MoviesLocation`	`5`	Returns the user's movies.
`QDesktopServices::PicturesLocation`	`6`	Returns the user's pictures.
`QDesktopServices::TempLocation`	`7`	Returns the system's temporary directory.
`QDesktopServices::HomeLocation`	`8`	Returns the user's home directory.
`QDesktopServices::DataLocation`	`9`	Returns a directory location where persistent application data can be stored. QCoreApplication::applicationName and QCoreApplication::organizationName should work on all platforms.
`QDesktopServices::CacheLocation`	`10`	Returns a directory location where user-specific non-essential (cached) data should be written.

This enum was introduced or modified in Qt 4.4.

成员函数

`[static]` QString QDesktopServices::displayName(StandardLocation type)

Use QStandardPaths::displayName()

`[static]` QString QDesktopServices::storageLocation(StandardLocation type)

Use QStandardPaths::writableLocation()

Note: when porting QDesktopServices::DataLocation to QStandardPaths::DataLocation, a different path will be returned.

QDesktopServices::DataLocation was GenericDataLocation + "/data/organization/application", while QStandardPaths::DataLocation is GenericDataLocation + "/organization/application".

Also note that 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


  QDesktopServices::storageLocation(QDesktopServices::DataLocation)

with


  QStandardPaths::writableLocation(QStandardPaths::GenericDataLocation) +
  "/data/organization/application"

(assuming an organization name and an application name were set).
