Normally, all the behavior of the program is determined by its code written on Java. FXML files usually only determine the appearance of the window, but not its behaviour. In order for the programme to be able to respond to the user ' s actions, the elements of the interface (boxes, input elements, etc.) need to be linked to the so-called " listeners " , or, in other words, processors for all types of events to be processed (compression, focus of entry, etc.). The listener (listener) is a fragment of the software code that will be implemented when the event occurs. In the simplest case, it might look like, myButton.setOnAction(e -> System.out.println("Нажата кнопка " + ((Button)(e.getSource())).getText())); Here with the button. myButton connecting a listener to a type event ActionEventwhich will be educated by a button when compressed. In this fragment of the circumference containing information on the event presented in the code ethe element of the interface that caused the event is extracted.e.getSource()(in this case, it will be the ea button itself) and its text shall be inserted into the console.In some cases, the event processors may be added directly to the FXML file (see nap. http://tutorials.jenkov.com/javafx/fxml.html Paragraph FXML Event HandlersBut that's the practice, I'd say, of amateur.

I don't understand the full meaning of the code as a whole, so I hope my word helps. In fact, there are several options, for example:Set up a method in the controller, change the button text and after each choice (after the window button or any action) call that method and hand over the type of ice cream selected.If there's any trouble, I can add the code, but it's tomorrow and the need.

from new FXMLLoader() It will not be possible to go anywhere, because it keeps the hierarchy and binding of a specific element. By the way, the code can be improved a little, loader.load() returns the root element that can be inserted setGraphic()♪Reading the file in the method load()He's from InputStream collects data. As resource data are not remembranced, the disc reads every time. It is logical that the file can be replaced by a data flow, for example:private static byte[] xml; public TaskCell() { final FXMLLoader loader = new FXMLLoader(); try { if(xml == null) { xml = getClass() .getResource("/Presenter/Components/TaskList/TaskCard.fxml") .openStream() .readAllBytes(); } loader.setController(this); rootElement = loader.load(new ByteArrayInputStream(xml)); } catch (IOException exception) { System.out.println("Failed to load 'TaskCard.fxml' component:\n" + exception.getMessage()); } }

There's option, he's not related to your code, but maybe you're interested in a possible tool. :public class SlideLiveTimer extends Task<Void> { @Override protected Void call() throws Exception { int counts = 0; while (counts&lt;100){ Thread.sleep(105); counts++; } SlideModalError.hideStatus.play(); SlideModalError.showsStatus = false; return null; } } Challenge from another class:SlideLiveTimer slt = new SlideLiveTimer(); Thread thread = new Thread(slt); thread.setDaemon(true); thread.start(); In this example, after some time, object X is hidden.You're gonna need to go to your class, expand the Taska, put the controller in the designer. Then, in the cycle, perform operations. Modifications of GUI-related changes should be introducedPlatform.runLater(()->{ // ВАш КОД }); The parameters transmitted (in this case the coordinates should be final (Pred challenge Platform). I can't recommend security here because there's a possibility of sinchron.

Pane has a basic function to accommodate the elements, needs to monitor positioning on its own to avoid excesses. In this case, it is better to use, for example, javafx.scene.layout.GridPane.

In the first copy of Wtf, start method is generated, hereinafter line final Parent root = loader.load(); a second copy of Wtf, noteList initiated by annotations. Next in code, we go back to the first copy of Wtf, where a noteList is not initialized and cause null any method to anyone else. Make the same class of entrance to the program and make a bad decision by the controller.

Looks like you're doing something wrong.(1) We need to link fxml with the counter-eller. To this end, annotation is required over the counteralling class:@ViewController(value = "/fxml/timer.fxml", title = "Таймер") (2) In fxml file, specify id for the element.<Label fx:id="timeLabel" /> (3) In the counter-insurer, define this element@FXML private Label timeLabel; The name of the id and the name of the variable must coincide, then javafx will inject.(4) Possible use @PostConstructthe method of this annotation will be followed by the establishment of a counteraller.@PostConstruct public void init() { DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("'Today' dd.MM.yyyy, HH:mm:ss"); ScheduledExecutorService executor = Executors.newSingleThreadScheduledExecutor(); executor.scheduleWithFixedDelay(() -> { LocalDateTime now = LocalDateTime.now(); String nowFormatted = dateTimeFormatter.format(now); Platform.runLater(() -> timer.setText(nowFormatted)); }, 0, 1, TimeUnit.SECONDS); }

Do you have a fxml file?If you don't, here's the code you have to work that you want.Main.javapublic class Main extends Application{ public static void main(String[] args) { Application.launch(args); } @Override public void start(Stage stage) throws Exception { Parent root = FXMLLoader.load(getClass().getResource("Main.fxml")); Scene scene = new Scene(root); stage.setScene(scene); stage.setTitle("Пример"); stage.setWidth(250); stage.setHeight(200); stage.show(); } } Main.fxml <?import java.lang.*?> <?import javafx.scene.Group?> <?import javafx.scene.control.Button?> <Group fx:id="root" xmlns:fx="http://javafx.com/fxml/1" fx:controller="MainController"> <MenuButton <!-- свойства кнопки --> onAction="#click" /> </Group> MainController.java public class MainController { @FXML private MenuButton btn; @FXML private void click(ActionEvent event) { //делайте что то со своей кнопкой } }

The point was that Chart in this case uses String type values as meanings on the abssis axis, that is, in fact, signatures. As a result, there was a mistake, even though the lineChart type was marked.

JavaFX allows UI to be updated only through its flows, or leaves an exception to the type:Exception in thread "Thread-4" java.lang.IllegalStateException: Not on FX application thread; currentThread = Thread-4 I'd recommend you take a look at the package first. https://docs.oracle.com/javase/8/javafx/interoperability-tutorial/fx_concurrency.htm ♪

It's better for animationTimer.Simple example:import javafx.animation.AnimationTimer; import javafx.application.Application; import javafx.event.EventHandler; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.input.KeyCode; import javafx.scene.input.KeyEvent; import javafx.scene.paint.Color; import javafx.scene.shape.Box; import javafx.scene.shape.Circle; import javafx.stage.Stage; public class BasicGraphicsDemo3 extends Application implements EventHandler<KeyEvent> { final int WIDTH = 600; final int HEIGHT = 400; double ballRadius = 40; double ballX = 100; double ballY = 200; double xSpeed = 4; public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) throws Exception { stage.setTitle("Basic JavaFX demo"); Group root = new Group(); Scene scene = new Scene(root, WIDTH, HEIGHT); // Bouncing Ball Circle circle = new Circle(); circle.setCenterX(ballX); circle.setCenterY(ballY); circle.setRadius(ballRadius); circle.setFill(Color.BLUE); root.getChildren().add(circle); // need to attach KeyEvent caller to a Node of some sort. // How about an invisible Box? final Box keyboardNode = new Box(); keyboardNode.setFocusTraversable(true); keyboardNode.requestFocus(); keyboardNode.setOnKeyPressed(this); root.getChildren().add(keyboardNode); stage.setScene(scene); stage.show(); AnimationTimer animator = new AnimationTimer() { @Override public void handle(long arg0) { // UPDATE ballX += xSpeed; if (ballX + ballRadius &gt;= WIDTH) { ballX = WIDTH - ballRadius; xSpeed *= -1; } else if (ballX - ballRadius &lt; 0) { ballX = 0 + ballRadius; xSpeed *= -1; } // RENDER circle.setCenterX(ballX); } }; animator.start(); } @Override public void handle(KeyEvent arg0) { if (arg0.getCode() == KeyCode.SPACE) { xSpeed *= -1; } } } In the above example, the ball changes the direction when it hits the gap.

Add 3 label Total choiceBox<ChoiceBox id="choiceBox"> <Label text="One"/> <Label text="Two"/> <Label text="Three"/> </ChoiceBox>

The decision was found after the clarification of Tsyclop.The animation code, too.It's animation. Both start with zero. That's why Label's flashing at the same time. And if you have to put a second animation to play, it's easy if you can get it in the counteraller code. Thank you all for understanding!

Call reader.readLine() twice in cycle (both cycle and condition) whileYou're poking through the line, that's it. readLine Changes the index at every call. Standard use:String s = reader.readLine(); while ( s != null ) { String[] s1 = s.split("\t"); xCoords.add(Double.parseDouble(s1[0])); yCoords.add(Double.parseDouble(s1[1])); s = reader.readLine(); }

Warning Because of what's in fxml There's something on the rut cell:<Pane ... xmlns="http://javafx.com/javafx/11.0.1" ...> Which means you've created a document from underneath. JDK11You're gonna start under. JDK8and java car is not sure that everything is right and knows that all the elements used are in place.And 30 symbols need to be written so that the code with the question and the errors that arise and the warnings throw a text away, not a picture, because the text can be copied and it is easier to read visually.

I need a name button in the counteraller. id buttons fxmlin method initialize() That button can be hanged. EventHandler♪ setOnAnction♪ setOnMouseClicked and anything.Other option: button fxml add attribution onAction with the name of the compression method in the counteraller in such a way as: onAction="#onClickMethod"♪Controllerpublic class Controller { @FXML private Button button; @FXML public void onClickMethod() { button.setText("Thanks!"); } @FXML public void initialize() { button.addEventHandler(MouseEvent.MOUSE_CLICKED, mouseEvent -&gt; button.setText("Thanks!")); } } fxml<Button fx:id="button" onAction="#onClickMethod" text="Click Me!"/> https://devcolibri.com/javafx-2-%D0%BE%D0%B1%D1%80%D0%B0%D0%B1%D0%BE%D1%82%D1%87%D0%B8%D0%BA-%D1%81%D0%BE%D0%B1%D1%8B%D1%82%D0%B8%D0%B9-button/

Thank you, Andrew Bystrov. Indeed, we need to add: --add-modules javafx.web

I think I found what's needed. Class Main: package sample; 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 Main extends Application{ @Override public void start(Stage primaryStage) throws IOException { Parent root = FXMLLoader.load(getClass().getResource("sample.fxml")); primaryStage.setTitle("Tabel Test"); primaryStage.setScene(new Scene(root, 600, 400)); primaryStage.show(); } public static void main (String[] args) { launch(); } } Class Controller: package sample; import java.net.URL; import java.util.ResourceBundle; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.event.ActionEvent; import javafx.fxml.FXML; import javafx.scene.control.CheckBox; import javafx.scene.control.TableColumn; import javafx.scene.control.TableView; import javafx.scene.control.cell.PropertyValueFactory; public class Controller { @FXML private ResourceBundle resources; @FXML private URL location; @FXML private TableView&lt;Names&gt; tabel; @FXML private TableColumn&lt;Names, Boolean&gt; col1; @FXML private CheckBox checkBox; @FXML private TableColumn&lt;Names, String&gt; col2; private static boolean chck; @FXML void checkBoxInitialize(ActionEvent event) { chck = checkBox.isSelected() ? true : false; for (Names n : data) { n.setCheck(chck); } } ObservableList&lt;Names&gt; data = FXCollections.observableArrayList(); @FXML void initialize() { col1.setCellValueFactory(new PropertyValueFactory&lt;Names, Boolean&gt;("check")); col2.setCellValueFactory(new PropertyValueFactory&lt;Names, String&gt;("name")); for (int i = 1; i &lt; 10; i++) { data.add(new Names("Name " + i)); } tabel.setItems(data); } } Class Names: package sample; import javafx.scene.control.CheckBox; public class Names { private CheckBox check; private String name; public CheckBox getCheck() { return check; } public void setCheck(Boolean x) { if(x) { check.setSelected(true); } else { check.setSelected(false); } } public String getName() { return name; } public void setName(String name) { this.name = name; } public Names(String name) { check = new CheckBox(); this.name = name; } } FXML file (sample.fxml): <?xml version="1.0" encoding="UTF-8"?> <?import javafx.scene.control.CheckBox?> <?import javafx.scene.control.TableColumn?> <?import javafx.scene.control.TableView?> <?import javafx.scene.layout.AnchorPane?> <AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/10.0.1" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Controller"> <children> <TableView fx:id="tabel" editable="true" layoutX="32.0" layoutY="47.0" prefHeight="200.0" prefWidth="200.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0"> <columns> <TableColumn fx:id="col1" prefWidth="26.0" resizable="false"> <graphic> <CheckBox fx:id="checkBox" mnemonicParsing="false" onAction="#checkBoxInitialize" prefHeight="17.0" prefWidth="23.0" /> </graphic> </TableColumn> <TableColumn fx:id="col2" minWidth="0.0" prefWidth="572.0" text="Имя" /> </columns> </TableView> </children> </AnchorPane>

The problem was FXML itself. SceneBuilder The following fields shall be placed in the root of the default:maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" If we load and deploy this fxml by JavaFX, they seem to be ignored. But TornadoFX takes them into account and ultimately does not extend the whole Tab. I mean, these fields from the root leg are better removed.

That's how I put the controller in the program:FXMLLoader pageLoader = new FXMLLoader(getClass().getResource("Page.fxml")); PageController pageController = new PageController(); pageLoader.setController(pageController); Parent root = pageLoader.load(); stage.setScene(newScene(root)); P.S., the mistake was very stupid, just forgot to put in a controller. I answered if someone's time was saved.
