thread sleep

[nodevelop]

hi,
what's wrong with this code?
paint() method shows rects all togheter in the same time.
why Thread.sleep() doesn't work?
(the same paint method used in an applet works well.)



import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class M1 extends MIDlet {
private Schermo1 mioSchermo = new Schermo1();

public void startApp() {
Display.getDisplay(this).setCurrent(mioSchermo);

}
public void pauseApp() {

}
public void destroyApp(boolean unconditional) {

}
}

class Schermo1 extends Canvas implements CommandListener {
int y = 10;
public void commandAction(Command c, Displayable mioSchermo){
}
public void paint(Graphics g) {

try {
for (int n = 5; n > 0; n--) {
y = y + 10;
g.setColor(100 + y,100 + y,50 + y);
g.fillRect(y, y, 50, 50);
Thread.sleep(1000);

}
} catch (InterruptedException e) {}
}

}

It works. It just does a bit different than in an applet

Some phones (also Nokia's Series 40, Series 60) have internally double buffered screens.

That is, nothing is actually drawn until paint() method finishes

The exact same question with an answer.
