From a JavaRanch Forum post. Key press and release handlers are added on the scene and update movement state variables recorded in the application. An animation timer hooks into the JavaFX pulse mechanism (which by default will be capped to fire an event 60 times a second) – so that is a kind of game … Read more
Why your code does not work The loader creates a new AnchorPane, but you never add the new pane to a parent in the scene graph. Quick Fix Instead of: content = (AnchorPane) FXMLLoader.load(“vista2.fxml”); Write: content.getChildren().setAll(FXMLLoader.load(“vista2.fxml”)); Replacing the content children with your new vista. The content itself remains in the scene graph, so when you … Read more
The default behavior of the FXMLLoader is to create a new instance of the controller class and use that instance as the controller. Specifically, the FXMLLoader does something like: Read the root FXML element. If the root FXML element has a fx:controller attribute, then If a controller already exists, throw an exception, otherwise create an … Read more
This question is really a duplicate of: Javafx PropertyValueFactory not populating Tableview, but I’ll specifically address your specific case, so it’s clear. Suggested solution (use a Lambda, not a PropertyValueFactory) Instead of: aColumn.setCellValueFactory(new PropertyValueFactory<Appointment,LocalDate>(“date”)); Write: aColumn.setCellValueFactory(cellData -> cellData.getValue().dateProperty()); For more information, see this answer: Java: setCellValuefactory; Lambda vs. PropertyValueFactory; advantages/disadvantages How do you use a … Read more
You can use Timeline for that task: Timeline fiveSecondsWonder = new Timeline( new KeyFrame(Duration.seconds(5), new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent event) { System.out.println(“this is called every 5 seconds on UI thread”); } })); fiveSecondsWonder.setCycleCount(Timeline.INDEFINITE); fiveSecondsWonder.play(); for the background processes (which don’t do anything to the UI) you can use old good java.util.Timer: new Timer().schedule( … Read more
Short version of answer: Use getClass().getResource(…) or SomeOtherClass.class.getResource(…) to create a URL to the resource Pass either an absolute path (with a leading /) or a relative path (without a leading /) to the getResource(…) method. The path is the package containing the resource, with . replaced with /. Do not use .. in the … Read more
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 … Read more
