Sample Code

Posted by Vikas on February 13, 2002 at 4:53 PM

HI Siva,

Thanks to Markus.

Following is the Code:

import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Color;
import java.applet.*;
import java.awt.*;

public class SimpleApplet extends Applet{

private Image Buffer;
private Graphics gBuffer;

String text = "I'm a simple applet Test";

public void init() {
//create graphics buffer, the size of the applet
text = "I'm a simple applet";
setBackground(Color.cyan);
}
public void start() {
System.out.println("starting...");
}
public void stop() {
System.out.println("stopping...");
}
public void destroy() {
System.out.println("preparing to unload...");
}
public void paint(Graphics g){
// Commented Non Working Code
// System.out.println("Paint");
// g.setColor(Color.blue);
// g.drawRect(0, 0, getSize().width -1,getSize().height -1);
// g.setColor(Color.red);
// g.drawString(text, 15, 25);
//

System.out.println("Paint");
Buffer=createImage(size().width,size().height);
gBuffer=Buffer.getGraphics();
gBuffer.setColor(Color.blue);
gBuffer.drawRect(0, 0,
getSize().width -1,
getSize().height -1);
gBuffer.setColor(Color.red);
gBuffer.drawString(text, 15, 25);
g.drawImage (Buffer,0,0, this);
}
}

But there seems to be a lot of bugs in some IE-Versions, which ignore Commands like setColor an that draw only white Rectangle or Polygons. A bad workaround, which functions, is draw all in an Image-Object and then call drawImage to draw the Image in the Graphics Object.
