ControlFX Action Usage - javafx-8

Question

I have an application with both MenuBar and ToolBar. I found in ControlsFX documentation that it is possible to define the action event logic in a different class and assign it to buttons, menuitems and togglebuttons define by fxml. More or less like a router in php frameworks(e.g laravel).
Here is the description
An action in JavaFX can be used to separate functionality and state from a control. For example, if you have two or more controls that perform the same function (e.g. one in a Menu and another on a toolbar), consider using an Action object to implement the function. An Action object provides centralized handling of the state of action-event-firing components such as buttons, menu items, etc. The state that an action can handle includes text, graphic, long text (i.e. tooltip text), and disabled.
The problem is that i was not able to get enough info to use it in my application. Here is a simple example i have so far
public class RootController implements Initializable {
#FXML
private MenuItem menuOne;
#FXML
private MenuItem menuTwo;
#FXML
private MenuItem menuThree;
#FXML
private Button tbOne;
#FXML
private Button tbTwo;
#FXML
private Button tbThree;
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}

Main
public class MainApp extends Application {
public static void main(String[] args) throws Exception {launch(args); }
public void start(Stage stage) throws Exception {
FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/root.fxml"));
loader.setController(new RootController());
Scene scene = new Scene((Parent)loader.load(), 400, 200);
stage.setTitle("ControlFX Action API");
stage.setScene(scene);
stage.show();
}
}
AppRouter
public class AppRouter {
public AppRouter(){
ActionMap.register(this);
}
public void testOne(){
System.out.println("testOne");
}
public void testTwo(){
System.out.println("testTwo");
}
public void testThree(){
System.out.println("testThree");
}
}
My problem is how to assign the methods in AppRouter to buttons and menuitems in the RootController
Update
I will gladly accept anyother alternative answer too.

Answer 1

Let's assume that you will create an Instance of AppRouter class in
the Application class:
public class MainApp extends Application {
AppRouter appRouter = new AppRouter(); //here................
public static void main(String[] args) throws Exception {launch(args); }
public void start(Stage stage) throws Exception {
FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/root.fxml"));
loader.setController(new RootController());
Scene scene = new Scene((Parent)loader.load(), 400, 200);
stage.setTitle("ControlFX Action API");
stage.setScene(scene);
stage.show();
}
}
Then you can have a method which accepts an AppRouter,in the
FXMLController:
public class RootController implements Initializable {
#FXML
private MenuItem menuOne;
#FXML
private MenuItem menuTwo;
#FXML
private MenuItem menuThree;
#FXML
private Button tbOne;
#FXML
private Button tbTwo;
#FXML
private Button tbThree;
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
public void acceptRouter(AppRouter router){
//register or call router methods here
}
}
How to get the controller you just created into the MainApp class?
FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/root.fxml"));
loader.setController(new RootController());
RootController controller = loader.getController(); //simple as this,although check the method name if it is the same cause i added this from phone
controller.acceptRouter(appRouter);
