class FileTreeWatcher(SignalEmitter): (source)
Helper object that adds signals for file changes. It can be used for the watcher attribute for file system objects.
When use the object itself will call the "watcher" on changes and if the object is a folder it will pass on the "watcher" to child objects. So you can effectively watch a whole tree.
