public interface ListEventListener<E>
Listens and responds to changes in a dynamic list of objects. This could be implemented by a GUI widget such as a table or combo box to repaint, add, or remove elements when the underlying data changes.
List changes are represented by a ListEvent
.
When a thread requires notification on the Swing thread for GUI display, the user should not add the implementation of this interface as a listener directly. Instead use a EventThreadProxy, which receives events on the list thread and then fires them on the Swing thread.

Method Detail |
---|
void listChanged(ListEvent<E> listChanges)
It is mandatory that the calling thread has obtained the write lock on the source list. This is because the calling thread will have written to the source list to cause this event. This condition guarantees that no writes can occur while the listener is handling this event. It is an error to write to the source list while processing an event.
