如何从其他班级打开新场景

Question

我有一个简单的按钮，我想点击并打开一个新场景，但我在另一个类中创建了新场景，但它不起作用，也没有显示我的错误。 这是我的Controller类

public class Controller
 {
  public TextField txtUsername;
  public TextField txtEmail;
  public TextField txtPass;
  public TextField txtPhone;
  public Button btnLogin;
 }
public void buttonClicked()
{
   Chattingform chattingform = new Chattingform ();
}

这是我的Chattingform类

public class Chattingform extends Application
{



@Override
public void start (Stage primaryStage) throws Exception {

    FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("Chattingform.fxml"));
    try {
        Parent root = fxmlLoader.load();
        Stage stage = new Stage();
        stage.initModality(Modality.APPLICATION_MODAL);
        stage.setOpacity(1);
        stage.setTitle("Exchat");
        stage.setScene(new Scene (root, 450, 450));
        stage.showAndWait();
    }catch ( IOException io )
    {
        JOptionPane.showMessageDialog (null, "Could not open ");
    }
}

从我的经验来看，所有JavaFX控制器都有：

@Override
public void initialize(URL url, ResourceBundle rb) {
    // TODO
}
