// greeter.js
// Load Nashorn predefined scripts to import JavaFX specific classes
// and packages
load("fx:base.js");
load("fx:controls.js");

// Define the start() method of the JavaFX application class
function start(stage) {
var nameLbl = new Label("Enter your name:");
var nameFld = new TextField();
var msg = new Label();
msg.style = "-fx-text-fill: blue;";
// Create buttons
var sayHelloBtn = new Button("Say Hello");
var exitBtn = new Button("Exit");

// Call the same fucntion sayHello() when the user
nameFld.onAction = sayHello;
// Add the event handler for the Exit button
exitBtn.onAction = function() {
Platform.exit();
};
// Create the root node
var root = new VBox();
root.style = "-fx-padding: 10;" +
"-fx-border-style: solid inside;" +
"-fx-border-width: 2;" +

"-fx-border-color: blue;";
// Set the vertical spacing between children to 5px

// Add children to the root node
root.children.addAll(msg, new HBox(nameLbl, nameFld,
sayHelloBtn, exitBtn));
