Questions tagged [qfilesystemmodel]

A QFileSystemModel is a class from the Qt toolkit which provides a data model for the local filesystem.

The QFileSystemModel class gives access to the local filesystem. It provides functions for renaming and removing files and directories, and for creating new directories. In the simplest case, it can be used with a suitable display widget (such as a QTreeView) as part of a browser or filter.

The official Qt documentation can be found here for Qt 4.8 and here for Qt 5.
