Class RevealedDialogDispatcherFactory

java.lang.Object

spin.off.DialogDispatcherFactory

spin.demo.dispatcher.RevealedDialogDispatcherFactory

All Implemented Interfaces:

DispatcherFactory

public class RevealedDialogDispatcherFactory
extends DialogDispatcherFactory

Implementation of a dispatcher which uses dialogs to dispatch events.
Due to the inability to change the owner of a dialog (after creation) this class has to create a fresh dialog for each invocation on the bean. This admittedly inperformant behaviour could be improved by pooling the dialogs on a per-owner basis (e.g. utilizing a WeakHashMap).
Subclasse might want to offer cancel functionality, display real progress or show an animated image (e.g. the famous Netscape icon).
