Interface ProgressListener

All Known Implementing Classes:

RunPanel, SymbolPanel, TrainPanel

public interface ProgressListener

Designed to allow objects to listen in on the progress of long OCR-related operations. Training, adapting symbols and running the OCR routine currently require a listener, which will be called when significant events happen to alert the user of progress.
