CallbackTracksboardItemVolumeChanged delegate |

Remarks
Callback delegate invoked when a volume operation is performed on a specific item on the TracksBoard, for example when the position of a volume point is modified or the vertical position of the amplitude line has been changed: this callback can be set through a call to the CallbackTracksboardItemVolumeChangedSet method.
The usage of this delegate is alternative to the TracksBoardItemVolumeChanged event.
