#include <QFSFileEngine>
Inherits QAbstractFileEngine.
This class was introduced in Qt 4.1.
The QFSFileEngine class implements Qt's default file engine.
This class is part of the file engine framework in Qt. If you only want to access files or directories, use QFile, QFileInfo or QDir instead.
QFSFileEngine is the default file engine for accessing regular files. It is provided for convenience; by subclassing this class, you can alter its behavior slightly, without having to write a complete QAbstractFileEngine subclass. To install your custom file engine, you must also subclass QAbstractFileEngineHandler and create an instance of your handler.
It can also be useful to create a QFSFileEngine object directly if you need to use the local file system inside QAbstractFileEngine::create(), in order to avoid recursion (as higher-level classes tend to call QAbstractFileEngine::create()).
Constructs a QFSFileEngine.
Constructs a QFSFileEngine for the file name file.
Destructs the QFSFileEngine.
Returns the canonicalized form of the current path used by the file engine for the drive specified by fileName.
On Windows, each drive has its own current directory, so a different path is returned for file names that include different drive names (e.g. A: or C:).
See also setCurrentPath().
Returns the list of drives in the file system as a list of QFileInfo objects. On unix, Mac OS X and Windows CE, only the root path is returned. On Windows, this function returns all drives (A:, C:, D:, etc.).
Returns the home path of the current user.
See also rootPath().
Opens the file handle fh in openMode mode. Returns true on success; otherwise returns false.
This is an overloaded member function, provided for convenience.
Opens the file descriptor fd in openMode mode. Returns true on success; otherwise returns false.
Returns the root path.
See also homePath().
Sets the current path (e.g., for QDir), to path. Returns true if the new path exists; otherwise this function does nothing, and returns false.
See also currentPath().
Returns the temporary path (i.e., a path in which it is safe to store temporary files).
