java.lang.Object
- uk.ac.starlink.util.gui.WeakListDataListener

All Implemented Interfaces:

java.util.EventListener, javax.swing.event.ListDataListener
```
public class WeakListDataListener
extends java.lang.Object
implements javax.swing.event.ListDataListener
```
List data listener which delegates to another one as long as it is reachable, but only retains a weak reference to it. Adding a listener to an object in this way will not prevent the listener (and any of its references) from being garbage collected.
