In the simplest case, it can be used with a suitable display + widget as part of a browser or filter. + + QFileSystemModel can be accessed using the standard interface provided by + QAbstractItemModel, but it also provides some convenience functions that are + specific to a directory model. + The fileInfo(), isDir(), fileName() and filePath() functions provide information + about the underlying files and directories related to items in the model. + Directories can be created and removed using mkdir(), rmdir(). + + \note QFileSystemModel requires an instance of \l QApplication. + + \section1 Example Usage + + A directory model that displays the contents of a default directory + is usually constructed with a parent object: + + \snippet shareddirmodel/main.cpp 2 + + A tree view can be used to display the contents of the model + + \snippet shareddirmodel/main.cpp 4 + + and the contents of a particular directory can be displayed by + setting the tree view's root index: + + \snippet shareddirmodel/main.cpp 7 + + The view's root index can be used to control how much of a + hierarchical model is displayed. QFileSystemModel provides a convenience + function that returns a suitable model index for a path to a + directory within the model. + + \section1 Caching and Performance + + QFileSystemModel will not fetch any files or directories until setRootPath() + is called. This will prevent any unnecessary querying on the file system + until that point such as listing the drives on Windows. + + QFileSystemModel uses a separate thread to populate itself so it will not + cause the main thread to hang as the file system is being queried. + Calls to rowCount() will return 0 until the model populates a directory. + + QFileSystemModel keeps a cache with file information.
