JPanel's wait(long timeout) function

Question

Hey,
I wanted to make a line go across the screen when the user clicks a button. I tried calling the paint(graphics) function in the button's actionPerformed(..) function, in a loop so that it can show the line move across the screen.
in the paint(..) method, I want the line to appear at a location, then I want the panel to wait 1 sec. so everytime teh paint method is called, a new line is drawn, and is now in a location, let's say, 10 pixels from the previous line; then the panel must wait 1 sec before going to the next step.
It should look like a continuous flowing line across the screen.
But when I state, in the paint(..) method:
try{
            wait(1000);
          catch(Exception e){
          }it does not wait the whole 1 second. I know that it must be another component calling the "notify(..)" method, but is there anyway I can make the JPanel wait for a specific amount of time?
How can I solve this ?
thanks ;)

hey thanks for the replies.
I have so far:
int count=0;
int linepos=0;
private void PlayClicked(){
    play=true;
    stop=false;
    if (pause==false){
      linepos=100;
      repaint();
    while (count<15){
      call();
  private void call() {
      linepos=linepos+20;
      try {
         Thread.sleep(100);
      catch (InterruptedException ie) {      }
      repaint();
      try {
         Thread.sleep(100);
      catch (InterruptedException ie) {      }
      repaint();
   }and in paint(..) I have
if (play || pause) {
          g.drawLine(linepos,300,linepos,500);
}K my prob is that now, the thread completely stops until the last loop cycle, so that I only see the last position of the line.
I first tried to make the thread sleep only once, but what I figured was that it sleeps, then it takes a very small time to set the new location, so it seems as if it automatically sleeps again (in the next cycle of the loop). so if i made it sleep twice, once after the new location has been set, and once after the repaint has been called, it would show the line.
but it doesnt work. :s
is there another way of doing this ? :)
thanks :D
