Java FX changing value of Label from different scene

Question

I have two scenes. The first scene invokes second scene using the following code.

@FXML
private void confirmation(ActionEvent event) throws IOException{
 Stage c         


        

Answer 1

Assuming that you have a controller called:confirmation_controller.java'. inside that controller, you have a public method getProceedLabel() that returns a reference for the label called Proceed. you can try the following code:

 Stage confirmation_stage;
 Parent confirmation;
 confirmation_stage=new Stage();
 FXMLLoader loader = new FXMLLoader(getClass().getResource("Confirmation.fxml"));
 confirmation = loader.load();
 confirmation_controller controller = loader.getController();
 Label label = controller.getProceedLabel();
 label.setText("..."):
 confirmation_stage.setScene(new Scene(confirmation));
 confirmation_stage.initOwner(generate_button.getScene().getWindow());
 confirmation_stage.show();
