Programming Reference:GenericVisualization Class

Presenting data to the operator user

Your filter may have information that it wants to present to the user - e.g., the EEG signal might appear graphically in a window, or an application task log should be presented. Packaging this information into core messages, and sending these to the operator module, is handled by the GenericVisualization class. Typically, to visualize data this way, you will add a data member of type GenericVisualization to your filter class - see Programming Tutorial:Implementing a Signal Processing Filter for an example.
