JavaFX have ProgressMonitorDialog like jface? ProgressIndicator don't help.

Question

javaFX have ProgressMonitorDialog like jface? ProgressIndicator don't help.
I need a loading page like ProgressMonitorDialog in jface.
Then when i do some time-consuming operation, a loading page will be loaded until the operation is over.
The problem is that when i use a Service class, i must put the time-consuming operation outside the Platform.runLater(new Runnable().
and i must put the javaFX controls set operation in the Platform.runLater(new Runnable(), it's very difficult to seperate them sometimes.
ProgressIndicator doesn't help in this case.
Thank you.
     button.setOnMouseClicked(new EventHandler<MouseEvent>() {
               public void handle(MouseEvent me) {
                    stage.show();
                    final Task<Integer> task = new Task<Integer>()
@Override
protected Integer call()
throws Exception
// TODO Auto-generated method stub
System.out.println("ssss");
try
Thread.sleep(5000);
catch (InterruptedException e)
// TODO Auto-generated catch block
e.printStackTrace();
Platform.runLater(new Runnable()
@Override
public void run()
                                   // when do something time-consuming here, then stage.Show(); above can't be loaded immediately when button clicked //,why? The thread will always wait the time-consuming operation.
button2.setText("dddddddd");
stage.close();
// TODO Auto-generated method stub
return null;
                    Service<Integer> service = new Service<Integer>()
@Override
protected Task<Integer> createTask()
// TODO Auto-generated method stub
return task;
service.start();
                    }});

These will cause changes to the Task (and Service) properties, and these changes will be made on the FX Application thread for you.
You can also listen for changes to the state property of the service, or use the various utility methods such as setOnSucceeded(...) to execute code when the service finishes running. Again, these methods are executed on the FX Application thread, so you don't need to manage the Platform.runLater(...) yourself.
ProgressIndicator doesn't help in this case.Why not?
There are lots of examples out there. Here's another one :)
