Problem Setting offscreen background
Hi
I'm trying to create an applet with an image moving down the screen which i have been able to do, but when i try to set background of the offscreen image i get the following when compiling : symbol : method setBackground(java.awt.Color). Is there another way to set the offscreen background. Here is the code.
Many Thanks
Dean
import java.awt.*;
publicclass KelvinIndexLogoextends java.applet.Appletimplements Runnable{
// Define Objects & Variables
Image logo, workspace;
Graphics offscreen;
Thread runner;
int logoY = 0;
int logoStop;
// Background RGB values
int backRed= 221;
int backGreen = 221;
int backBlue = 221;
boolean firstRun =true;
publicvoid init(){
String imageName = getParameter("logo");
setBackground(new Color(backRed, backGreen, backBlue));
// Get the logo image if the logo parameter has been specified
if(imageName !=null){
logo = getImage(getCodeBase(), imageName);
}
}
publicvoid start(){
if(runner ==null){
runner =new Thread(this);
runner.start();
}
}
publicvoid stop(){
if(runner !=null){
runner =null;
}
}
publicvoid run(){
// Move the Logo down from the top of the applet
Thread thisThread = Thread.currentThread();
while(runner == thisThread){
repaint();
try{
Thread.sleep(50);
}catch(InterruptedException e){}
// Would not get the correct image height in the init method
// therefore created first run bolean to set the start & Stop points
if(firstRun){
logoY= 0 - logo.getHeight(this);
logoStop = getSize().height - logo.getHeight(this);
firstRun =false;
}
logoY++;
if(logoY == logoStop){
runner =null;
}
}
}
publicvoid paint(Graphics screen){
// Create the workspace & offscreen objects on each iteration so
// image is cleared every time and no black trail appears on text
workspace = createImage(getSize().width, getSize().height);
offscreen = workspace.getGraphics();
offscreen.setBackground(this.getBackground());
if(logo !=null){
offscreen.drawImage(logo, 0, logoY,null);
}
// Draw workspace to screen & set background colour
screen.drawImage(workspace, 0,0,this);
}
publicvoid update(Graphics screen){
paint(screen);
}
}
