Description
TChangeLink is a class used to perform notifications when images
are added or deleted in TImageList. TChangelink provides event handlers that
are signalled when the image list performs actions requiring the
notification. TImageList allows multiple objects to subscribe to the change
notifications, and each subscriber is represented by a TChangeLink class
instance.
TChangeLink instances are passed to TCustomImageList (and descendants) in the RegisterChanges method.
