Detailed Description
Watcher that monitors file changes.
This class can be used similar to QFileSystemWatcher. Additionally it offers a delayed fileChanged signal.
This behaviour is required for the following reason: Normally QFileSystemWatcher emits a signal every time a file is changed. This causes several signals for large files (one for each flush of the buffer).
