Chapter 3 - Applet Functions

1. Statusbar Messages.

/* This Applet will show status bar messages in your browser.
We will use an ActionListener to practice on it.

import java.awt.*;
import java.awt.event.*;
import java.applet.*;

public class StatusExample extends Applet implements ActionListener
     //The text in this field will be shown
     TextField statusField;
     // when this button is clicked
     Button statusButton;

     public void init() 
          setLayout(new FlowLayout());
          statusButton = new Button("Set Status");
          statusField = new TextField("Type here");
          // You can add ActionListeners to TextFields too.
          // An ActionEvent will be triggered when the user presses
          // ENTER in the textfield.

     public void actionPerformed(ActionEvent act) 
          if (act.getSource() == statusButton)
           // The simple method to set a Status bar message.
           // This will take the text from thze textfield and append some extra
           // info to it.
             getAppletContext().showStatus(statusField.getText() +"(WithButtonAction)");
           getAppletContext().showStatus(statusField.getText() + " (With FieldAction)");

// It's really easy. Next example is about opening web pages with 
// a browser through an applet. 
// Go to ShowDocumentExample
