Example from lab 1/10/01

Note: The use of static below was a quick
fix and we will discuss later. Normally this
is not the approach to use.

import javax.swing.*; // Import the Swing classes
import java.awt.event.*; // for the WindowAdapter and WindowEvent classes
import java.awt.*; // for the Container class

// This is your Swing applet (by extending JApplet).
public class THelloApplicationOnly {

        static JFrame f = new JFrame("THello");
	static JLabel l = new JLabel("My New Label");
	static JLabel lab2 = new JLabel("Second label");
	static JTextArea ta = new JTextArea("Init. string", 10, 30);
	static JScrollPane sp = new JScrollPane(ta);

    // When you run this program as an application.
    // The main method instantiates the application frame.
    public static void main(String[] args) {
	sp.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
	sp.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);

	Container c = f.getContentPane();

	c.setLayout(new FlowLayout( FlowLayout.CENTER, 20, 30 ));		

        // Add the applet to the JFrame (to it's content pane).
        c.add(l);
	c.add(lab2);
	c.add(sp);

        // Add the listener to close the frame.
        f.addWindowListener(new WindowEventHandler());

        // Assign the frame size and display it.
        f.setSize(400, 300); // frame: width=300, height = 150
        f.show(); // Display the frame

	forLoop(15);
    }

    private static void forLoop(int howMany) {
	ta.setText("");
		
	for (int i = 0; i < howMany; i++) {
		ta.append("" + i + '\n');
	}
    }
}


import java.awt.event.*;

// Class to close the frame and exit the application.


public class WindowEventHandler extends WindowAdapter {
    	public void windowClosing(WindowEvent e) {
        	System.exit(0);
    	}
}
