Method Detail

notifyPainting

public void notifyPainting(Rectangle damage,
                           Map dirtyRegions)
Notifies the listener that the listened to object is painting. The damage rectangle may be null or empty. This indicates the dirty regions were clipped or not visible. But for objects such as the Thumbnail, notification still needs to occur. The map of dirty regions is passed to allow the listener to determine if it needs to update, for instance when a particular figure is painting.

Parameters:
damage - The area being painted
dirtyRegions - a Map of figures to their dirty regions

notifyValidating

public void notifyValidating()
Notifies the listener that the listened to object is validating.
