问题 I'm used to working with Swing to create GUIs but for a recent project I've chosen to switch to JavaFX. I'm having some trouble with recreating a certain layout I used to make using a GridLayout. I desire the following behavior: 2 columns that scale proportionally with the size of their parent that center their contents.

FXML example: <?xml version="1.0" encoding="UTF-8"?> <?import java.lang.*?> <?import java.util.*?> <?import javafx.scene.*?> <?import javafx.scene.control.*?> <?import javafx.scene

问题 I am trying to drag and drop labels on top of each other. I have a list of labels called starsAndBars, and every label has this called on it as it is created: private void giveDragAndDropProperties(Label label) { //Enable drag actions to pick up the label label.setOnDragDetected(new EventHandler<MouseEvent>() { public void handle(MouseEvent event) { System.out.println("Drag and drop started!"); Dragboard db = label.startDragAndDrop(TransferMode.ANY); ClipboardContent content = new

问题 I am new to FXML and I am trying to create a handler for all of the button clicks using a switch . However, in order to do so, I need to get the elements using and id. I have tried the following but for some reason (maybe because I am doing it in the controller class and not on the main) I get a stack overflow exception. public class ViewController { public Button exitBtn; public ViewController() throws IOException { Parent root = FXMLLoader.load(getClass().getResource("mainWindow.fxml"));
