enum QDesktopServices:: StandardLocation

使用 QStandardPaths::StandardLocation (見 storageLocation () for porting notes)

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

常量	值	描述
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.

該枚舉在 Qt 4.4 引入或被修改。

成員函數文檔編製

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

使用 QStandardPaths::displayName ()

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

使用 QStandardPaths::writableLocation ()

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

QDesktopServices::DataLocation was GenericDataLocation + "/data/organization/application" ，而 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).
