Graphics, AWT, Swing I part

Graphics offscreenGraphics;

offscreenImage = createImage(size().width, size().height);

offscreenGraphics = offscreenImage.getGraphics();

offscreenGraphics.drawImage(img, 10, 10, this);

g.drawImage(offscreenImage, 0, 0, this);

 The following app works fine, but when I start it, I cannot close it using the X at

the right top of the form...

Please help me on the following. I m just starting to use java (JDK1.3). The

following app works fine, but when I start it, I cannot close it using the X

at the right top of the form. What should I add to fix this problem? The

source is shown below.

import java.awt.*;

import java.awt.event.*;

public class MyApplication extends Frame{

   public static void main(String args[]){

      Frame f = new Frame("MyApp");

      f.setLayout(new FlowLayout());

      f.add(new Button("A"));

      f.setVisible(true);

   }

}

Answer: You should add a listener to handle the closing of the window when the X

box gets clicked on.

f.addWindowListener(new WindowAdapter(){

   public void windowClosing(WindowEvent evt){

      System.exit(0);

   }

});

Read on this, and other ways to do it, in the sections dealing with

event handling, in whichever Java text you are using.

How can I set a JFrame to be full screen at the start of a program? I want no

borders, no titles and I just want to use the entire screen.

Answer: Try using JWindow instead, that one can be customized to have no borders

or titles... as for size, I think you can use

setBounds(GraphicsEnvironment.getLocalGraphicsEnvironment(). 

getDefaultScreenDevice().getDefaultConfiguration().getBounds());

to fill out the entire screen.

 Why can not I mix AWT and Swing?

Recently, I have been hearing a lot of people from various newsgroups and website

saying, java swing and awt can t be in the same application. They will not work

together and they might produce unexpected results. At the same time, i don t hear

people saying "why" you shouldn t use swing and awt together. Could someone out

there shed some light for me. Is their any logical reason why we shouldn t mix swing

and awt in the same application/applet. If there is a problem mixing swing and awt...
