ScrollPane Canvas repaint

Question

hello everybody,
I am adding a Canvas to a ScrollPane and adding different Strings to this Canvas using drawString method.
But the problem is that when i scroll up or sidewards then the contens are repainted and i can see the contents of the Canvas. How to do this.
Pls help me out.
I am putting down my code below.
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.applet.*;
public class MyTest extends Applet
MyScroll sc;
MyNewComponent newComponent;
public void init()
sc = new MyScroll();
newComponent = new MyNewComponent();
newComponent.setBounds(0,0,100,100);
newComponent.addElements();
sc.add(newComponent);
          sc.updateComponent(newComponent);
add(sc);
          sc.validate();
class MyNewComponent extends Canvas
Vector lines,fonts,colors;
int x=0,y=10;
Enumeration linesEnu,colorEnu;
public void MyComponent()
public void addElements()
lines = new Vector();
          fonts = new Vector();
colors = new Vector();
lines.addElement(" Jogi ");
lines.addElement(" Prabha ");
lines.addElement(" Kothi ");
lines.addElement(" Naresh ");
          lines.addElement(" Murthy");
          lines.addElement(" vishal ");
linesEnu = lines.elements();
               colorEnu = colors.elements();
public void paint(Graphics g)
Font f = new Font("SansSerif",Font.BOLD,10);
while(linesEnu.hasMoreElements())
g.setColor(Color.black);
g.setFont(f);
g.drawString(""+linesEnu.nextElement(),x,y );
y=y+10;
public void update(Graphics g)
          paint(g);
class MyScroll extends ScrollPane
     public void MyScroll()
     public void paint(Graphics g)
     public void update(Graphics g)
     public void updateComponent(MyNewComponent o)
          o.repaint();
Thanks in advance

In addition to the previous reply:
You use an enumeration to go through the strings, which you create outside the paint method. As an enumeration only allows you to go through its contents once, the first call to paint after adding a string will work ok, whereas all subsequent calls will find an empty enumeration, i.e. one, where hasMoreElements returns false immediately.
So, move your inesEnu = lines.elements() command to the paint-method, too.
