188 \class QDirModel -

189 \obsolete -

190 \brief The QDirModel class provides a data model for the local filesystem. -

191 -

192 \ingroup model-view -

193 \inmodule QtWidgets -

194 -

195 The usage of QDirModel is not recommended anymore. The -

196 QFileSystemModel class is a more performant alternative. -

197 -

198 This class provides access to the local filesystem, providing functions -

199 for renaming and removing files and directories, and for creating new -

200 directories. In the simplest case, it can be used with a suitable display -

201 widget as part of a browser or filer. -

202 -

203 QDirModel keeps a cache with file information. The cache needs to be -

204 updated with refresh(). -

205 -

206 QDirModel can be accessed using the standard interface provided by -

207 QAbstractItemModel, but it also provides some convenience functions -

208 that are specific to a directory model. The fileInfo() and isDir() -

209 functions provide information about the underlying files and directories -

210 related to items in the model. -

211 -

212 Directories can be created and removed using mkdir(), rmdir(), and the -

213 model will be automatically updated to take the changes into account. -

214 -

215 \note QDirModel requires an instance of \l QApplication. -
