IFRPageEvents Interface
This is a callback interface that is used for reporting events from the FRPage object to the listeners. This interface is implemented on the client-side. See the detailed implementation advice for your development tool in Working with Connectable Objects. Below you can find a short summary.
You need to implement the IFRPageEvents interface and "advise" object implementing the interface to the FRPage object. As the interface is derived from the IUnknown interface, the client object should also implement the IUnknown methods.
An object receiving notifications through this interface's methods may do the following inside the methods' implementation:
- Report percentage of document analysis, recognition, and export.
- Report recognizer tips and warnings to the user.
- Report information about completion of the operation.
