Detailed Description

MExtensionWatcher provides means to watch if either a given applet or a application extension has been updated by the package manager. If the change happens a corresponding signal will be emitted.

The user of this class is responsible for the lifecycle management of the watched entries. This class does not assume ownership of the items nor can it detect if they are deleted. The user must remove the item from this watcher before deleting the item. Otherwise desktop file modification notification leads to undefined behaviour, because the target item of the notification will not exist.
