JAVAFx transfer variable data in-between various scenes in the same controller class [duplicate] - variables

Question

How can I pass parameters to a secondary window in javafx? Is there a way to communicate with the corresponding controller?
For example:
The user chooses a customer from a TableView and a new window is opened, showing the customer's info.
Stage newStage = new Stage();
try
{
AnchorPane page = (AnchorPane) FXMLLoader.load(HectorGestion.class.getResource(fxmlResource));
Scene scene = new Scene(page);
newStage.setScene(scene);
newStage.setTitle(windowTitle);
newStage.setResizable(isResizable);
if(showRightAway)
{
newStage.show();
}
}
newStage would be the new window. The problem is, I can't find a way to tell the controller where to look for the customer's info (by passing the id as parameter).
Any ideas?

Answer 1

Using MVC
Most of this answer focuses on a direct call to pass a parameter from a calling class to the controller.
If instead, you want to decouple the caller and controller and use a more general architecture involving a model class with settable and listenable properties to achieve inter-controller communication, see the following basic overview:
Applying MVC With JavaFx
Recommended Approach
This answer enumerates different mechanisms for passing parameters to FXML controllers.
For small applications I highly recommend passing parameters directly from the caller to the controller - it's simple, straightforward and requires no extra frameworks.
For larger, more complicated applications, it would be worthwhile investigating if you want to use Dependency Injection or Event Bus mechanisms within your application.
Passing Parameters Directly From the Caller to the Controller
Pass custom data to an FXML controller by retrieving the controller from the FXML loader instance and calling a method on the controller to initialize it with the required data values.
Something like the following code:
public Stage showCustomerDialog(Customer customer) {
FXMLLoader loader = new FXMLLoader(
getClass().getResource(
"customerDialog.fxml"
)
);
Stage stage = new Stage(StageStyle.DECORATED);
stage.setScene(
new Scene(loader.load())
);
CustomerDialogController controller = loader.getController();
controller.initData(customer);
stage.show();
return stage;
}
...
class CustomerDialogController {
#FXML private Label customerName;
void initialize() {}
void initData(Customer customer) {
customerName.setText(customer.getName());
}
}
A new FXMLLoader is constructed as shown in the sample code i.e. new FXMLLoader(location). The location is a URL and you can generate such a URL from an FXML resource by:
new FXMLLoader(getClass().getResource("sample.fxml"));
Be careful NOT to use a static load function on the FXMLLoader, or you will not be able to get your controller from your loader instance.
FXMLLoader instances themselves never know anything about domain objects. You do not directly pass application specific domain objects into the FXMLLoader constructor, instead you:
Construct an FXMLLoader based upon fxml markup at a specified location
Get a controller from the FXMLLoader instance.
Invoke methods on the retrieved controller to provide the controller with references to the domain objects.
This blog (by another writer) provides an alternate, but similar, example.
Setting a Controller on the FXMLLoader
CustomerDialogController dialogController =
new CustomerDialogController(param1, param2);
FXMLLoader loader = new FXMLLoader(
getClass().getResource(
"customerDialog.fxml"
)
);
loader.setController(dialogController);
Pane mainPane = loader.load();
You can construct a new controller in code, passing any parameters you want from your caller into the controller constructor. Once you have constructed a controller, you can set it on an FXMLLoader instance before you invoke the load() instance method.
To set a controller on a loader (in JavaFX 2.x) you CANNOT also define a fx:controller attribute in your fxml file.
Due to the limitation on the fx:controller definition in FXML, I personally prefer getting the controller from the FXMLLoader rather than setting the controller into the FXMLLoader.
Having the Controller Retrieve Parameters from an External Static Method
This method is exemplified by Sergey's answer to Javafx 2.0 How-to Application.getParameters() in a Controller.java file.
Use Dependency Injection
FXMLLoader supports dependency injection systems like Guice, Spring or Java EE CDI by allowing you to set a custom controller factory on the FXMLLoader. This provides a callback that you can use to create the controller instance with dependent values injected by the respective dependency injection system.
An example of JavaFX application and controller dependency injection with Spring is provided in the answer to:
Adding Spring Dependency Injection in JavaFX (JPA Repo, Service)
A really nice, clean dependency injection approach is exemplified by the afterburner.fx framework with a sample air-hacks application that uses it. afterburner.fx relies on JEE6 javax.inject to perform the dependency injection.
Use an Event Bus
Greg Brown, the original FXML specification creator and implementor, often suggests considering use of an event bus, such as the Guava EventBus, for communication between FXML instantiated controllers and other application logic.
The EventBus is a simple but powerful publish/subscribe API with annotations that allows POJOs to communicate with each other anywhere in a JVM without having to refer to each other.
Follow-up Q&A
on first method, why do you return Stage? The method can be void as well because you already giving the command show(); just before return stage;. How do you plan usage by returning the Stage
It is a functional solution to a problem. A stage is returned from the showCustomerDialog function so that a reference to it can be stored by an external class which may wish to do something, such as hide the stage based on a button click in the main window, at a later time. An alternate, object-oriented solution could encapsulate the functionality and stage reference inside a CustomerDialog object or have a CustomerDialog extend Stage. A full example for an object-oriented interface to a custom dialog encapsulating FXML, controller and model data is beyond the scope of this answer, but may make a worthwhile blog post for anybody inclined to create one.

Example for Spring Boot Dependency Injection
The question of how to do it "The Spring Boot Way", there was a discussion about JavaFX 2, which I anserwered in the attached permalink.
The approach is still valid and tested in March 2016, on Spring Boot v1.3.3.RELEASE:
https://stackoverflow.com/a/36310391/1281217
Sometimes, you might want to pass results back to the caller, in which case you can check out the answer to the related question:
JavaFX FXML Parameter passing from Controller A to B and back

Answer 2

I realize this is a very old post and has some great answers already,
but I wanted to make a simple MCVE to demonstrate one such approach and allow new coders a way to quickly see the concept in action.
In this example, we will use 5 files:
Main.java - Simply used to start the application and call the first controller.
Controller1.java - The controller for the first FXML layout.
Controller2.java - The controller for the second FXML layout.
Layout1.fxml - The FXML layout for the first scene.
Layout2.fxml - The FXML layout for the second scene.
All files are listed in their entirety at the bottom of this post.
The Goal: To demonstrate passing values from Controller1 to Controller2 and vice versa.
The Program Flow:
The first scene contains a TextField, a Button, and a Label. When the Button is clicked, the second window is loaded and displayed, including the text entered in the TextField.
Within the second scene, there is also a TextField, a Button, and a Label. The Label will display the text entered in the TextField on the first scene.
Upon entering text in the second scene's TextField and clicking its Button, the first scene's Label is updated to show the entered text.
This is a very simple demonstration and could surely stand for some improvement, but should make the concept very clear.
The code itself is also commented with some details of what is happening and how.

Answer 3

Here is an example for passing parameters to a fxml document through namespace.
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.layout.VBox?>
<VBox xmlns="http://javafx.com/javafx/null" xmlns:fx="http://javafx.com/fxml/1">
<BorderPane>
<center>
<Label text="$labelText"/>
</center>
</BorderPane>
</VBox>
Define value External Text for namespace variable labelText:
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.io.IOException;
public class NamespaceParameterExampleApplication extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws IOException {
final FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("namespace-parameter-example.fxml"));
fxmlLoader.getNamespace()
.put("labelText", "External Text");
final Parent root = fxmlLoader.load();
primaryStage.setTitle("Namespace Parameter Example");
primaryStage.setScene(new Scene(root, 400, 400));
primaryStage.show();
}
}

Answer 4

javafx.scene.Node class has a pair of methods
setUserData(Object)
and
Object getUserData()
Which you could use to add your info to the Node.
So, you can call page.setUserData(info);
And controller can check, if info is set. Also, you could use ObjectProperty for back-forward data transfering, if needed.
Observe a documentation here:
http://docs.oracle.com/javafx/2/api/javafx/fxml/doc-files/introduction_to_fxml.html
Before the phrase "In the first version, the handleButtonAction() is tagged with #FXML to allow markup defined in the controller's document to invoke it. In the second example, the button field is annotated to allow the loader to set its value. The initialize() method is similarly annotated."
So, you need to associate a controller with a node, and set a user data to the node.

Answer 5

This WORKS ..
Remember first time you print the passing value you will get null,
You can use it after your windows loaded , same for everything you want to code for any other component.
First Controller
try {
Stage st = new Stage();
FXMLLoader loader = new FXMLLoader(getClass().getResource("/com/inty360/free/form/MainOnline.fxml"));
Parent sceneMain = loader.load();
MainOnlineController controller = loader.<MainOnlineController>getController();
controller.initVariable(99L);
Scene scene = new Scene(sceneMain);
st.setScene(scene);
st.setMaximized(true);
st.setTitle("My App");
st.show();
} catch (IOException ex) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex);
}
Another Controller
public void initVariable(Long id_usuario){
this.id_usuario = id_usuario;
label_usuario_nombre.setText(id_usuario.toString());
}

Answer 6

You have to create one Context Class.
public class Context {
private final static Context instance = new Context();
public static Context getInstance() {
return instance;
}
private Connection con;
public void setConnection(Connection con)
{
this.con=con;
}
public Connection getConnection() {
return con;
}
private TabRoughController tabRough;
public void setTabRough(TabRoughController tabRough) {
this.tabRough=tabRough;
}
public TabRoughController getTabRough() {
return tabRough;
}
}
You have to just set instance of controller in initialization using
Context.getInstance().setTabRough(this);
and you can use it from your whole application just using
TabRoughController cont=Context.getInstance().getTabRough();
Now you can pass parameter to any controller from whole application.

Answer 7

Yes you can.
You need to add in the first controller:
YourController controller = loader.getController();
controller.setclient(client);
Then in the second one declare a client, then at the bottom of your controller:
public void setclien(Client c) {
this.client = c;
}

Answer 8

Here is an example for using a controller injected by Guice.
/**
* Loads a FXML file and injects its controller from the given Guice {#code Provider}
*/
public abstract class GuiceFxmlLoader {
public GuiceFxmlLoader(Stage stage, Provider<?> provider) {
mStage = Objects.requireNonNull(stage);
mProvider = Objects.requireNonNull(provider);
}
/**
* #return the FXML file name
*/
public abstract String getFileName();
/**
* Load FXML, set its controller with given {#code Provider}, and add it to {#code Stage}.
*/
public void loadView() {
try {
FXMLLoader loader = new FXMLLoader(getClass().getClassLoader().getResource(getFileName()));
loader.setControllerFactory(p -> mProvider.get());
Node view = loader.load();
setViewInStage(view);
}
catch (IOException ex) {
LOGGER.error("Failed to load FXML: " + getFileName(), ex);
}
}
private void setViewInStage(Node view) {
BorderPane pane = (BorderPane)mStage.getScene().getRoot();
pane.setCenter(view);
}
private static final Logger LOGGER = Logger.getLogger(GuiceFxmlLoader.class);
private final Stage mStage;
private final Provider<?> mProvider;
}
Here is a concrete implementation of the loader:
public class ConcreteViewLoader extends GuiceFxmlLoader {
#Inject
public ConcreteViewLoader(Stage stage, Provider<MyController> provider) {
super(stage, provider);
}
#Override
public String getFileName() {
return "my_view.fxml";
}
}
Note this example loads the view into the center of a BoarderPane that is the root of the Scene in the Stage. This is irrelevant to the example (implementation detail of my specific use case) but decided to leave it in as some may find it useful.

Answer 9

You can decide to use a public observable list to store public data, or just create a public setter method to store data and retrieve from the corresponding controller

Answer 10

Why answer a 6 year old question ?
One the most fundamental concepts working with any programming language is how to navigate from one (window, form or page) to another. Also while doing this navigation the developer often wants to pass data from one (window, form or page) and display or use the data passed
While most of the answers here provide good to excellent examples how to accomplish this we thought we would kick it up a notch or two or three
We said three because we will navigate between three (window, form or page) and use the concept of static variables to pass data around the (window, form or page)
We will also include some decision making code while we navigate
public class Start extends Application {
#Override
public void start(Stage stage) throws Exception {
// This is MAIN Class which runs first
Parent root = FXMLLoader.load(getClass().getResource("start.fxml"));
