FX

Introduction

File: "fx1.java"

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.layout.StackPane;

import javafx.stage.Stage;

import javafx.event.* ;

public class fx1 extends Application

{

// launch the application

public void start(Stage stageObj )

{

// set title for the stage

stageObj.setTitle("creating buttons");

// create a button

Button buttonObj = new Button("button");

buttonObj.setOnAction(new EventHandler<ActionEvent>() {

@Override public void handle(ActionEvent e) {

System.out.println( "Button clicked." ) ;

}

});

// create a stack pane

StackPane pane = new StackPane();

// add button

pane.getChildren().add(buttonObj);

// create a scene

Scene sc = new Scene(pane, 200, 200);

// set the scene

stageObj.setScene(sc);

stageObj.show();

}

public static void main(String args[])

{

// launch the application

launch(args);

}

}

Output:

The "EventHandler" is not from the AWT package. In fact all the classes used in the above program are from the Java FX package. A "stage" is a top level container ( similar to a Frame in AWT or a JFrame in Swing ) . A scene can contain visual elements . It can contain panes that have layout managers and can contain buttons, text fields and other graphic elements.
