How can I change from one frame to another by closing the first frame in javaFX ?

I have the following code, but it does not work, it does not open the other windows:

The problem is that it does not open the next window, nor does it show me anything.

Try doing it this way, for example in the showMenuAdministrator function that jumps to the next window after clicking the open window button.

public void mostrarMenuAdministrador(Event event) {
    try {

        Parent root = FXMLLoader.load(getClass().getResource("cMenuTutor.fxml"));
        Scene scene = new Scene(root);
        Stage appStage = (Stage) ((Node) event.getSource()).getScene().getWindow();
        appStage.setScene(scene);
        appStage.toFront();
        appStage.show();

    } catch (Exception e) {
    }
}

note that you add as an argument of the function the event you pass to get the Stage.

in the other functions that do the same thing in the TestVistanas class, you should do it like that.

Notice that in the window VentanaPrincipalController the windowNew function would look like this.

@FXML
private void ventanaNew(ActionEvent event) throws IOException {
    System.out.println("Entra boton");
    validaUsuario();

    ProgramaPrincipal.mostrarMenuAdministrador(event);

}

you must pass as an argument the event you capture by pressing the button open window. You just have to worry about the dimensions of the windows and so on, in JavaFX there are two ways to change the view, one is to change the panels without modifying the window and another is to change the window directly.

It also includes the option to change the window in the controllers and not always in a main class, it can be less cumbersome when it comes to window logic.

I suggest you reuse your Stage to avoid the creation of new Stages, what you can do is re-inject your FXML with FXMLLoader.

Try using this method:

public class AppController extends Application {

    @FXML
    private AnchorPane primaryWindow;

    @Override
    public void start(Stage primaryStage) {
        try {
             Stage primaryStage = (Stage) primaryWindow.getScene().getWindow();
             primaryStage.setScene(loadView("Reservation", "reservationStyles"));
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

   //Si deseas hacer alguna enumeracion para tus vistas o 
   //un array con las vistas que tienes creadas es mucho mas legible y facil de reutilizar.
   public static Scene loadView(String viewName, String cssFile) {
       Parent root = FXMLLoader.load(AppController.class.getClass().getResource(viewName + ".fxml"));
                Scene scene = new Scene(root);
                scene.getStylesheets().add(PlayListController.class.getClass()
                        .getResource(cssFile + ".css").toExternalForm());
                return scene;
   }

 }

I hope it will help you. Greetings.
