Detailed DescriptionThe 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()).
Method DocumentationQFSFileEngine.__init__ (self)Constructs a QFSFileEngine.
QFSFileEngine.__init__ (self, QString file)Constructs a QFSFileEngine for the file name file.
