This exercise create a Rectangle object with RectangleBuilder, set width according to its parent, scene.

package javafxrect;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.scene.shape.RectangleBuilder;
import javafx.stage.Stage;
/**

 */
public class JavaFXRect extends Application {
 
 @Override
 public void start(Stage primaryStage) {
 //Group root = new Group();
 VBox root = new VBox(5); // spacing = 5
 root.setPadding(new Insets(10, 10, 10, 10));
 
 Scene scene = new Scene(root, 300, 250);
 
 Button btn = new Button();
 btn.setText("java-buddy.blogspot.com");
 btn.setOnAction(new EventHandler<ActionEvent>() {
 @Override
 public void handle(ActionEvent event) {
 System.out.println("Hello World!");
 }
 });
 
 //Create Rectangle with RectangleBuilder
 Rectangle rect = RectangleBuilder
 .create()
 .width(scene.getWidth() - 20)
 .height(50)
 .fill(Color.AZURE)
 .stroke(Color.rgb(150, 150, 150))
 .strokeWidth(3)
 .build();
 root.getChildren().addAll(rect, btn);
 primaryStage.setTitle("Hello World!");
 primaryStage.setScene(scene);
 primaryStage.show();
 }
 public static void main(String[] args) {
 launch(args);
 }
}

Next:
- Auto adjust width of Rectangle when parent resized
