From where to start All Swing Application Framework applications must subclass either the Application class or its SingleFrameApplication subclass. The SingleFrameApplication adds a default main GUI frame, retrieves and injects default resources, and uses the ApplicationContext to save and restore simple session state. Session state includes UI component location, size, and configuration.

Example subclasses the Application class public class BasicFrameworkApp extends Application { private JFrame mainFrame; private JLabel label; protected void startup() { mainFrame = new JFrame("BasicFrameworkApp"); mainFrame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE); mainFrame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) { mainframe.setVisible(false); exit();}}); label = new JLabel("Hello, world!"); mainFrame.add(label);mainFrame.pack();mainFrame.setVisible(true);} public static void main(String[] args) { Application.launch(BasicFrameworkApp.class, args); } }

Example subclasses the SingleFrameApplication class public class BasicSingleFrameApp extends SingleFrameApplication { JLabel label; protected void startup() { getMainFrame().setTitle("BasicSingleFrameApp"); label = new JLabel("Hello, world!"); label.setFont(new Font("SansSerif", Font.PLAIN, 22)); show(label);} public static void main(String[] args) { Application.launch(BasicSingleFrameApp.class, args); }}
