JavaFX的屬性經常通過綁定來綜合。這是一種表達變量間關系的機制。可以將一個目標對象和一個源對象綁定，如果源對象中的值改變了，則目標對象也將自動改變。目標對象稱為綁定對象或綁定屬性，源對象稱為可綁定對象或可觀察對象。下。下列程序是對《Java 程序語言設計》其中一道習題的實現（原答案並不完整）：
1 import javafx.application.Application; 2 import javafx.scene.Scene; 3 import javafx.scene.layout.Pane; 4 import javafx.scene.paint.Color; 5 import javafx.scene.shape.Line; 6 import javafx.scene.shape.Rectangle; 7 import javafx.stage.Stage; 8 9 public class java1414 extends Application { 10 @Override // Override the start method in the Application class 11 public void start(Stage primaryStage) { 12 Pane pane = new Pane(); 13 double paneWidth = 200; 14 double paneHeight = 200; 15 16 // Draw the front rectangle 17 Rectangle r1 = new Rectangle(); 18 r1.xProperty().bind(pane.widthProperty().multiply(0.05)); 19 r1.yProperty().bind(pane.heightProperty().multiply(0.30)); 20 r1.widthProperty().bind(pane.widthProperty().multiply(0.75)); 21 r1.heightProperty().bind(pane.heightProperty().multiply(0.60)); 22 r1.setFill(new Color(1, 1, 1, 0)); 23 r1.setStroke(Color.BLACK); 24 25 // Draw the back rectangle 26 Rectangle r2 = new Rectangle(); 27 r2.xProperty().bind(pane.widthProperty().multiply(0.15)); 28 r2.yProperty().bind(pane.heightProperty().multiply(0.06)); 29 r2.widthProperty().bind(pane.widthProperty().multiply(0.75)); 30 r2.heightProperty().bind(pane.heightProperty().multiply(0.60)); 31 r2.setFill(new Color(1, 1, 1, 0)); 32 r2.setStroke(Color.BLACK); 33 34 // Connect the corners 35 Line line1 = new Line(); 36 line1.startXProperty().bind(pane.widthProperty().multiply(0.05)); 37 line1.startYProperty().bind(pane.heightProperty().multiply(0.30)); 38 line1.endXProperty().bind(pane.widthProperty().multiply(0.15)); 39 line1.endYProperty().bind(pane.heightProperty().multiply(0.06)); 40 Line line2 = new Line(); 41 line2.startXProperty().bind(pane.widthProperty().multiply(0.05)); 42 line2.startYProperty().bind(pane.heightProperty().multiply(0.90)); 43 line2.endXProperty().bind(pane.widthProperty().multiply(0.15)); 44 line2.endYProperty().bind(pane.heightProperty().multiply(0.66)); 45 Line line3 = new Line(); 46 line3.startXProperty().bind(pane.widthProperty().multiply(0.80)); 47 line3.startYProperty().bind(pane.heightProperty().multiply(0.30)); 48 line3.endXProperty().bind(pane.widthProperty().multiply(0.90)); 49 line3.endYProperty().bind(pane.heightProperty().multiply(0.06)); 50 Line line4 = new Line(); 51 line4.startXProperty().bind(pane.widthProperty().multiply(0.80)); 52 line4.startYProperty().bind(pane.heightProperty().multiply(0.90)); 53 line4.endXProperty().bind(pane.widthProperty().multiply(0.90)); 54 line4.endYProperty().bind(pane.heightProperty().multiply(0.66)); 55 56 pane.getChildren().addAll(r1, r2, line1, line2, line3, line4); 57 58 // Create a scene and place it in the stage 59 Scene scene = new Scene(pane, paneWidth, paneHeight); 60 primaryStage.setTitle("Exercise14_14"); // Set the stage title 61 primaryStage.setScene(scene); // Place the scene in the stage 62 primaryStage.show(); // Display the stage 63 } 64 }
