Class CellVisualUpdateEvent

java.lang.Object

org.eclipse.nebula.widgets.nattable.layer.event.CellVisualChangeEvent

org.eclipse.nebula.widgets.nattable.layer.event.CellVisualUpdateEvent

All Implemented Interfaces:

ILayerEvent, IVisualChangeEvent

public class CellVisualUpdateEvent
extends CellVisualChangeEvent

Specialization of the CellVisualChangeEvent. The only difference is the handling of this type of event in the NatTable event handling. While the CellVisualChangeEvent causes a whole redraw operation of the visible part (which is necessary to update everything if a data value has change, for example important for conditional styling), this event only forces to redraw the specified cell itself. This is for example necessary for hover styling, where redrawing everything is not necessary and would cause lags in applying hover styling.
