Class BlinkLayer<T>

java.lang.Object
  org.eclipse.nebula.widgets.nattable.layer.AbstractLayer
      org.eclipse.nebula.widgets.nattable.layer.AbstractLayerTransform
          org.eclipse.nebula.widgets.nattable.blink.BlinkLayer<T>

Type Parameters:

T - Type of the Bean in the backing IDataProvider

All Implemented Interfaces:

ILayer, ILayerListener, IUniqueIndexLayer, IPersistable

public class BlinkLayer<T>
extends AbstractLayerTransform
implements IUniqueIndexLayer

Blinks cells when they are updated. Returns blinking cell styles for the cells which have been updated. Every time its asked for config labels: Checks the UpdateEventsCache for changes to the cell If a cell is updated The cell is tracked as 'blinking' and blinking config labels are returned A TimerTask is started which will stop the blinking after the blink period is over

Method Detail

dispose

public void dispose()

Specified by:

dispose in interface ILayer

Overrides:

dispose in class AbstractLayerTransform

getConfigLabelsByPosition

public LabelStack getConfigLabelsByPosition(int columnPosition,
                                            int rowPosition)

Specified by:

getConfigLabelsByPosition in interface ILayer

Overrides:

getConfigLabelsByPosition in class AbstractLayerTransform

resolveConfigTypes

public LabelStack resolveConfigTypes(ILayerCell cell,
                                     Object oldValue,
                                     Object newValue)

Find the IBlinkingCellResolver from the ConfigRegistry. Use this to find the config types associated with a blinking cell.

Parameters:

cell - the cell

oldValue - the old value

newValue - the new value

Returns:

a LabelStack containing resolved config types associated with the cell

handleLayerEvent

public void handleLayerEvent(ILayerEvent event)

Description copied from class: AbstractLayer

Handle layer event notification. Convert it to your context and propagate UP. If you override this method you MUST NOT FORGET to raise the event up the layer stack by calling super.fireLayerEvent(event) - unless you plan to eat the event yourself.

Specified by:

handleLayerEvent in interface ILayerListener

Overrides:

handleLayerEvent in class AbstractLayer

Parameters:

event - the event

setBlinkingEnabled

public void setBlinkingEnabled(boolean enabled)

getColumnPositionByIndex

public int getColumnPositionByIndex(int columnIndex)

Specified by:

getColumnPositionByIndex in interface IUniqueIndexLayer

getRowPositionByIndex

public int getRowPositionByIndex(int rowIndex)

Specified by:

getRowPositionByIndex in interface IUniqueIndexLayer

setBlinkDurationInMilis

public void setBlinkDurationInMilis(int blinkDurationInMilis)
