 |
|
Hello,
could anyone help Java-Dummy with Mac OSX (3.9 and 4.2)?
I found this little applet below, but it doesn't work with OSX. It is
well doing the pause on Win XP and Mac OS9.
Could you give me a tip or link, how to create java-code which works on
nearly all systems?
Thank you!
Lothar
here is the applet:
import java.applet.*;
import java.awt.*;
public class Scheibea extends Applet{
public Scheibea(){
setBackground(Color.green);
}
public void zeitschleife(){
try {Thread.sleep(500);}
catch(InterruptedException e) {return;}
}
public void paint(Graphics stift){
for (int x=50;x<500;x=x+10){
stift.setColor(Color.red);
stift.drawOval(x,100,30,30);
zeitschleife();
stift.setColor(Color.blue);
stift.drawOval(x,100,30,30);
}
}
}

It looks like the Thread that's sleeping is not the same one that's
painting. To see another approach, have a look at the Sun example below;
it's included when you install Xcode:
