Examples of ILayerEvent

org.eclipse.nebula.widgets.nattable.layer.event.ILayerEvent
Event fired by the {@link ILayerCommandHandler} classes (usually to signal tohandling of a {@link ILayerCommand}). Every layer in the grid is given a chance to respond to an event via {@link ILayer#handleLayerEvent(ILayerEvent)}. @see ILayerEventHandler
