OnLongOperationFinished Method of the IDocumentViewerEvents Interface

This method is implemented on the client-side. It is called by ABBYY FineReader Engine after the end of a long-term processing operation (e.g., layout analysis, recognition) in Document Viewer. After the operation has been finished finished, Document Viewer is unlocked. If Document Viewer is connected to Component Synchronizer, the synchronized components locked by Synchronizer before the beginning of this operation are unlocked too.

The method informs the client that a long-term processing operation has been finished. You can use this method to unblock GUI elements of your application after such operations.
