| == When should I use a WeakListener |
| |
| You should use a link:DevFaqWeakListener.asciidoc[WeakListener] any time you are adding a listener to an object, but there is no code - and possibly no opportunity - to explicitly remove it. |
| |
| If the thing you are listening to does have some kind of observable life-cycle, it is preferable to explicitly add and detach listeners. |
| |
| But in the case that you are adding a listener which is never explicitly removed, it is good form to use `link:http://bits.netbeans.org/dev/javadoc/org-openide-util/org/openide/util/WeakListeners.html[WeakListeners]` |
