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

All Implemented Interfaces:

java.awt.event.ItemListener, java.util.EventListener
```
public class WeakItemListener
extends java.lang.Object
implements java.awt.event.ItemListener
```
Item 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.
