152 \class QFileSystemWatcher -

153 \inmodule QtCore -

154 \brief The QFileSystemWatcher class provides an interface for monitoring files and directories for modifications. -

155 \ingroup io -

156 \since 4.2 -

157 \reentrant -

158 -

159 QFileSystemWatcher monitors the file system for changes to files -

160 and directories by watching a list of specified paths. -

161 -

162 Call addPath() to watch a particular file or directory. Multiple -

163 paths can be added using the addPaths() function. Existing paths can -

164 be removed by using the removePath() and removePaths() functions. -

165 -

166 QFileSystemWatcher examines each path added to it. Files that have -

167 been added to the QFileSystemWatcher can be accessed using the -

168 files() function, and directories using the directories() function. -

169 -

170 The fileChanged() signal is emitted when a file has been modified, -

171 renamed or removed from disk. Similarly, the directoryChanged() -

172 signal is emitted when a directory or its contents is modified or -

173 removed. Note that QFileSystemWatcher stops monitoring files once -

174 they have been renamed or removed from disk, and directories once -

175 they have been removed from disk. -

176 -

177 \list -

178 \li \b Notes: -

179 \list -

180 \li On systems running a Linux kernel without inotify support, -

181 file systems that contain watched paths cannot be unmounted. -

182 -

183 \li The act of monitoring files and directories for -

184 modifications consumes system resources. This implies there is a -

185 limit to the number of files and directories your process can -

186 monitor simultaneously. On all BSD variants, for -

187 example, an open file descriptor is required for each monitored -

188 file. Some system limits the number of open file descriptors to 256 -

189 by default. This means that addPath() and addPaths() will fail if -

190 your process tries to add more than 256 files or directories to -

191 the file system monitor. Also note that your process may have -

192 other file descriptors open in addition to the ones for files -

193 being monitored, and these other open descriptors also count in -

194 the total. \macos uses a different backend and does not -

195 suffer from this issue. -
