All Implemented Interfaces:

Serializable

public class LostTarget
extends ErrorEvent

An error event sent by the adapter if the target was completely lost during a guiding process. However, the situation is not totally hopeless, so the target should not be aborted, but re-aquired.

This error is related to DropTarget. A possible interaction will be that the adapter always starts with a LostTarget error and only if the re-acquire fails, a DropTarget will be sent. Note that a LostTarget is only useful if a prior acquire has succeeded.
