public interface IVisualChangeEvent
extends ILayerEvent

An event which indicates a visible change to one or more cells in the layer. A visible change simply indicates that one or more cells should be redrawn. It does not imply a structural change to the layer. This means that cached structure does not need to be invalidated due to visible change events.

the layer that the visible change event is originating from.

getChangedPositionRectangles
