Building Your GUI Application with JavaFX

Problem

You want to build GUI applications with less work than writing Swing code.

Solution

JavaFX provides one alternative.

Discussion

JavaFX is a GUI package that ships with some releases of Java SE 7 and probably all re-
leases of Java SE 8. It is simpler to use, and also provides its own “standard” drag-and-drop
GUI builder (which is a separate download). Here is a “Hello, world” program in JavaFX
that simply prints to the standard output when a button is pressed:

import import javafx.application.Application javafx.application.Application ;

import import javafx.event.ActionEvent javafx.event.ActionEvent ;

import import javafx.event.EventHandler javafx.event.EventHandler ;

import import javafx.scene.Scene javafx.scene.Scene ;

import import javafx.scene.control.Button javafx.scene.control.Button ;

import import javafx.scene.layout.StackPane javafx.scene.layout.StackPane ;

import import javafx.stage.Stage javafx.stage.Stage ;

public public class class HelloFx HelloFx extends extends Application {

@Override
public

public void void start ( Stage stage ) {

stage . setTitle ( "JavaFX Hello!" );
Button btn = new

new Button ();
btn . setText ( "Run Greeting" );
btn . setOnAction ( new new EventHandler < ActionEvent >() {

@Override
public public void void handle ( ActionEvent e ) {

System . out . println ( "Hello from JavaFX" );

}

});

StackPane rootPane = new new StackPane ();

rootPane . getChildren (). add ( btn );
