Hi,

This very simple code shows function paint will be executed twice, why?

import java.applet.*;
import java.awt.*;
public class TestClass  extends Applet{
    int k=0;
    public void paint(Graphics g){
          g.drawString(Integer.toString(++k),50,20);
    }
}

Paint method is called whenever the component needs to be redrawn. Take a look at this

Cheers,

Thank you, Dian.
I am reading the link you suggested, a little too difficult for me though.

When you move the window, for example, it needs to be repainted, Then, AWT calls the paint method of each component. That's the basic idea.

Cheers,
