Perhaps the code is easier to follow as it’s all in one … Read more
I’m assuming you want this to happen when the user presses enter only while the TextField has focus. You’ll want use KeyEvent out of javafx.scene.input package and do something like this: field.setOnKeyPressed(new EventHandler<KeyEvent>() { @Override public void handle(KeyEvent ke) { if (ke.getCode().equals(KeyCode.ENTER)) { doSomething(); } } }); Using lambda: field.setOnKeyPressed( event -> { if( event.getCode() … Read more
You could do: FileChooser.ExtensionFilter extFilter = new FileChooser.ExtensionFilter(“TXT files (*.txt)”, “*.txt”); chooser.getExtensionFilters().add(extFilter); Here is a simple example: public class ExtensionFilterExample extends Application { public static void main(String[] args) { launch(args); } @Override public void start(final Stage primaryStage) { primaryStage.setTitle(“Extension Filter Example”); final Label fileLabel = new Label(); Button btn = new Button(“Open FileChooser”); btn.setOnAction(new EventHandler<ActionEvent>() … Read more
Unless you need the custom styling in this answer, I prefer the TitledPane with setCollapsible(false) solution by Andriy Kryvtsun. For use, see a TitledPane tutorial.

FXML Reference Introduction to FXML describes the syntax and usage patterns of the markup and is important to study when learning FXML. It does not define all elements usable in FXML. There will never be a full reference (nor xml schema) for FXML as it works by reflecting on Java classes in the classpath and … Read more
I’m running into a similar issue, as far as I can tell you have to deal with the error handling yourself. My solution is to update the UI via a method call: Something like: try { //blah… } catch (Exception e) { reportAndLogException(e); } … public void reportAndLogException(final Throwable t) { Platform.runLater(new Runnable() { @Override … Read more
Main Difference between Task and Service – One Time versus Repeated Execution A Task is a one off thing – you can only use a Task once. If you want to perform the same Task again, you need to construct a new Task instance. A Service has a reusable interface so that you can start … Read more
Uses javafx.scene.control.cell.CheckBoxTableCell<S,T> and the work’s done ! ObservableList< TableColumn< RSSReader, ? >> columns = _rssStreamsView.getColumns(); […] TableColumn< RSSReader, Boolean > loadedColumn = new TableColumn<>( “Loaded” ); loadedColumn.setCellValueFactory( new Callback<CellDataFeatures<RSSReader,Boolean>,ObservableValue<Boolean>>(){ @Override public ObservableValue<Boolean> call( CellDataFeatures<RSSReader,Boolean> p ){ return p.getValue().getCompleted(); }}); loadedColumn.setCellFactory( new Callback<TableColumn<RSSReader,Boolean>,TableCell<RSSReader,Boolean>>(){ @Override public TableCell<RSSReader,Boolean> call( TableColumn<RSSReader,Boolean> p ){ return new CheckBoxTableCell<>(); }}); […] columns.add( … Read more
