*/
this.createTextField("my_txt", 10, 10, 20, 200, 100);
my_txt.wordWrap = true;
this.createClassObject(mx.controls.UIScrollBar, "my_sb", 20);
// Set the target text field.
my_sb.setScrollTarget(my_txt);
// Size it to match the text field.
my_sb.setSize(16, my_txt._height);
// Move it next to the text field.
my_sb.move(my_txt._x + my_txt._width, my_txt._y);
// Scroll 2 lines per click of scroll arrow.
my_sb.lineScrollSize = 2;
// Scroll 5 lines per click of scroll track.
