How to scroll text.

Question

I want to scroll text on a touch device. But i have no idea how to do this. I read up on adobe that a mouse event will work, but a touch point could also be used, then they lost me talking about item rendering.
Can someone help me figure out how to scroll text on a touch enabled device?

You don't want to use just a while loop because once you get into the loop, it'll stay in there until you break out. Nothing else will be allowed to process. You'll want to use a Thread with a while loop inside.
I don't know if thise code will work. just wrote it off the top of my head. But something like that. You'll probably have to put extra white space in at the beginning of your scrollText so it starts on the far right side.
class ScrollArea extends JTextField implements Runnable
private Thread myThread;
private int i;
     public ScrollArea()
          myThread = new Thread(this);
          int scrolDist = textToScroll.length() + this.getColumns();
          i = 0;
     public void Run()
          int scrolDist = textToScroll.length() + this.getColumns();
          while(true)
                if(i == scrolDist)
                     i = 0;
                int scrolDist = textToScroll.length() + this.getColumns();
                this.setText(textToScroll.substring(i, scrolDist)
                i++;
     }
