Questions tagged [qfilesystemwatcher]

A QFileSystemWatcher is a class from the Qt toolkit which provides an interface for monitoring files and directories for modifications.

QFileSystemWatcher monitors the file system for changes to files and directories by watching a list of specified paths.

It emits signals whenever a file has been modified, renamed or removed from disk, or when a directory or its contents is modified or removed.

The official Qt documenation can be found here for Qt 4.8 or here for Qt 5.
