CREATING A WINDOWED PROGRAM

How to  Create an AWT-based application.

Creating applets is the most commom use for java's AWT
But,it is possible to create stand-alone AWT based applications to do this

  • simply create an instance of the window or windows you need inside main()
  • e.g. create frame window with in main()

The example program is  shown below:

// Create an AWT-based application.
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
// Create a frame window.
public class AppWindow extends Frame 
{
String keymsg = "This is a test.";
String mousemsg = "";
int mouseX=30, mouseY=30;
public AppWindow() 
{
addKeyListener(new MyKeyAdapter(this));
addMouseListener(new MyMouseAdapter(this));
addWindowListener(new MyWindowAdapter());
}
public void paint(Graphics g) {
g.drawString(keymsg, 10, 40);
g.drawString(mousemsg, mouseX, mouseY);
}
