# Interface INullSelectionListener

All Superinterfaces:
  `EventListener`, `ISelectionListener`

public interface INullSelectionListener extends ISelectionListener
Interface for listening to `null` selection changes.

This interface should be implemented by selection listeners that want to be notified when the selection becomes `null`. It has no methods. It simply indicates the desire to receive `null` selection events through the existing `selectionChanged` method. Either the part or the selection may be `null`.

Since:
  2.0
