效果图
代码如下：
1 import javafx.application.Application; 2 import javafx.scene.Scene; 3 import javafx.scene.layout.AnchorPane; 4 import javafx.scene.shape.Line; 5 import javafx.stage.Stage; 6 7 8 public class lineTry extends Application{ 9 // main was removed from slide due to space 10 11 public static void main(String[] args) { 12 lineTry.launch(args); 13 } 14 15 public void start(Stage stage) throws Exception { 16 stage.setTitle("Binding Example"); 17 AnchorPane root = new AnchorPane(); 18 Scene scene = new Scene(root, 250, 250); 19 20 System.out.println("Height: " + scene.heightProperty().getValue() ); 21 System.out.println("Width: " + scene.widthProperty().getValue() ); 22 23 for(int i = 0; i < 15; i++) 24 { 25 Line line1 = new Line(0, 0, 250, 250); 26 //line1.startXProperty().bind( scene.widthProperty()); 27 line1.startYProperty().bind( scene.heightProperty().divide(15.0/(i+1))); 28 line1.endXProperty().bind( scene.widthProperty().divide(15.0/(i+1))); 29 line1.endYProperty().bind( scene.heightProperty()); 30 31 Line line2 = new Line(0, 0, 250, 250); 32 line2.startXProperty().bind( scene.widthProperty().divide(15.0/(i+1))); 33 //line2.startYProperty().bind( scene.heightProperty()); 34 line2.endXProperty().bind( scene.widthProperty()); 35 line2.endYProperty().bind( scene.heightProperty().divide(15.0/(i+1))); 36 37 38 Line line3 = new Line(0, 250, 250, 0); 39 //line3.startXProperty().bind( scene.widthProperty().divide(15.0/(i+1)) ); 40 line3.startYProperty().bind( scene.heightProperty().divide(15.0/(14-i)) ); 41 line3.endXProperty().bind( scene.widthProperty().divide(15.0/(i+1)) ); 42 //line3.endYProperty().bind( scene.heightProperty()); 43 44 45 46 Line line4 = new Line(250, 0, 0,250); 47 line4.startXProperty().bind( scene.widthProperty()); 48 line4.startYProperty().bind( scene.heightProperty().divide(15.0/(i+1)) ); 49 line4.endXProperty().bind( scene.widthProperty().divide(15.0/(14-i)) ); 50 line4.endYProperty().bind( scene.heightProperty() ); 51 52 53 root.getChildren().addAll(line1,line2,line3,line4); 54 } 55 56 57 58 59 stage.setScene(scene); 60 stage.show(); 61 } 62 }
