JavaFX Using Netbeans Template Javfx FML Application - netbeans

Question

I thing it is a very silly question but I don't manage to to this. If you made a FXML-Template Project with Java, you got automatically three files. The view in XML, the controller and the start file in java.
I want to use the scene in the controller class but I don't know how to make a reference to do this.
Here is my example:
public class CatchTheScene extends Application {
private Scene scene;
private Parent root;
#Override
public void start(Stage stage) throws Exception {
root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
FXMLDocumentController controller = new FXMLDocumentController(this);
scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
/**
* #return the scene
*/
public Scene getScene() {
return scene;
}
/**
* #param scene the scene to set
*/
public void setScene(Scene scene) {
this.scene = scene;
}
}
public class FXMLDocumentController implements Initializable {
private CatchTheScene c;
#FXML
private Label label;
#FXML
private Button button;
#FXML
private AnchorPane root;
#FXML
private void handleButtonAction(ActionEvent event) {
System.out.println("You clicked me!");
label.setText("Hello World!");
}
public FXMLDocumentController(CatchTheScene c)
{
this.c = c;
}
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
c.getScene().addEventHandler(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>(){
#Override
public void handle(MouseEvent event) {
System.out.println("I am the scene and have been clicked");
}
});
}
}

I solved it now. First I gave in the Scene Builder a Code FX:ID named root to the root pane.
root is in the controller an object and I registered on root an EventListener.`
#FXML
private Canvas canvas;
#FXML
private AnchorPane root;
root.setOnKeyPressed(new EventHandler<KeyEvent>() {
#Override
public void handle(KeyEvent e) {
if (e.getCode() == KeyCode.LEFT) {
clownfish.setDx(-10);
clownfish.moveLeft();
}
if (e.getCode() == KeyCode.RIGHT) {
clownfish.setDx(-10);
clownfish.moveRight();
}
if (e.getCode() == KeyCode.UP) {
clownfish.setDy(-10);
clownfish.moveUp();
}
if (e.getCode() == KeyCode.DOWN) {
clownfish.setDy(-10);
clownfish.moveDown();
}
}
});
