Class ConcealedDialogDispatcherFactory

java.lang.Object

spin.off.DialogDispatcherFactory

spin.demo.dispatcher.ConcealedDialogDispatcherFactory

All Implemented Interfaces:

DispatcherFactory

public class ConcealedDialogDispatcherFactory
extends DialogDispatcherFactory

Implementation of a dispatcher which uses a pool of modal dialogs to dispatch events. The dialogs are concealed, i.e. they are located outside of the visible screen area.
Note that the Dispatchers created by this class are not usable for GUIs with Cancel functionality since they will block user access to all windows of your application during dispatching.
While this seems to be a major drawback this class nevertheless has its eligibility:

• It shows that Spin does no 'magic' nor any dirty tricks - every shown Dialog does the same.
• If your application really needs a Cancel functionality you should consider to use a real asynchronous solution as showed in spin.demo.async.AsyncGUI - please see also the caveat 'asynchronous'.
