146 \class QFileSystemWatcher -

147 \inmodule QtCore -

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

149 \ingroup io -

150 \since 4.2 -

151 \reentrant -

152 -

153 QFileSystemWatcher monitors the file system for changes to files -

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

155 -

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

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

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

159 -

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

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

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

163 -

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

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

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

167 removed. Note that QFileSystemWatcher stops monitoring files once -

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

169 they have been removed from disk. -

170 -

171 \note On systems running a Linux kernel without inotify support, -

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

173 -

174 \note Windows CE does not support directory monitoring by -

175 default as this depends on the file system driver installed. -

176 -

177 \note The act of monitoring files and directories for -

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

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

180 monitor simultaneously. On all BSD variants, for -

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

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

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

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

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

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

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

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

189 suffer from this issue. -
