How to close a stage after a certain amount of time JavaFX

Doja picture Doja · Dec 6, 2014 · Viewed 10.7k times · Source

I'm currently working with two controller classes.

In Controller1 it creates a new stage that opens on top of the main one.

Stage stage = new Stage();
Parent root = FXMLLoader.load(getClass().getResource("Controller2.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();

Now once that stage is open, I want it to stay open for about 5 seconds before closing itself.

Within Controller2, I've tried implementing something like

long mTime = System.currentTimeMillis();
long end = mTime + 5000; // 5 seconds 

while (System.currentTimeMillis() > end) 
{
      //close this stage  
} 

but I have no idea what to put inside the while loop to close it. I've tried all sorts and nothing works.

Use a PauseTransition:

PauseTransition delay = new PauseTransition(Duration.seconds(5));
delay.setOnFinished( event -> stage.close() );
delay.play();
