The StandardPaths singleton type provides methods for querying the standard system paths.
property url documentsFolder: StandardPaths.writableLocation(StandardPaths.DocumentsLocation)

|
string displayName ( StandardLocation type ) |
Returns a localized display name for the given location type or an empty QString if no relevant location can be found.
另请参阅 QStandardPaths::displayName ().
|
url findExecutable ( string executableName , list < string > paths ) |
Finds the executable named executableName 以指定 paths , or the system paths if paths is empty.
On most operating systems the system path is determined by the
PATH
environment variable. The directories where to search for the executable can be set in the paths argument. To search in both your own paths and the system paths, call findExecutable twice, once with paths set and once with paths empty. Symlinks are not resolved in order to preserve behavior for the case of executables whose behavior depends on the name they are invoked with.
注意：
On Windows, the usual executable extensions (from the PATHEXT environment variable) are automatically appended. For example, the findExecutable("foo") call finds
foo.exe
or
foo.bat
if present.
Returns the absolute file path to the executable, or an empty string if not found.
若给定 executableName is an absolute path pointing to an executable, its clean path is returned.

LocateFile
.

LocateFile
.

url writableLocation ( StandardLocation type ) |
Returns the directory where files of type should be written to, or an empty string if the location cannot be determined.
