int max = appContex.getBeanDefinitionCount();
updateProgress(0, max);
for (int k = 0; k < max; k++) {
try
{
Thread.sleep(50);
updateProgress(k+1, max);
}
catch(InterruptedException e)
{
System.exit(0);
}
}
return appContex;
}
};
}
};
service.start();
service.setOnRunning((WorkerStateEvent event) -> {
new FadeInLeftTransition(lblWelcome).play();
new FadeInRightTransition(lblRudy).play();
new FadeInTransition(vboxBottom).play();
});
service.setOnSucceeded((WorkerStateEvent event) -> {
config2 config = new config2();
config.newStage(stage, lblClose, "/chapitreapp/FXMLDocument.fxml", "Sample Apps", true, StageStyle.UNDECORATED, false);
});
}
}
where did I go wrong?

Answer 1

Something along these lines, in your onSucceeded event handler, or a method that it calls...
try {
URL url = this.getClass().getResource("nextScene.fxml");
if (url != null) {
FXMLLoader loader = new FXMLLoader(url);
Parent root = loader.load(url);
Scene newScene = new Scene(root);
this.getStage().setScene(newScene);
} else {
System.out.println("URL was null");
}
} catch (Exception e) {
System.out.println(e);
}
In your controller, you will need to have some means of setting the stage, either via a constructor that accepts the Stage object or via a setStage() method. I've used a getStage() method above to access the Stage and set the new Scene object on it.
You could also use the static FXMLLoader load method: Parent root = FXMLLoader.load(url);
