You can also create a UIScrollBar component instance and associate it with a text field at runtime

The following code creates a vertically oriented UIScrollBar instance and attaches it to the right
side of a text field instance named MyTextField:
// createClassObject like any other component. Name it vSB.
createClassObject(mx.controls.UIScrollBar, "vSB", 10);
// set the target text field
vSB.setScrollTarget(MyTextField);
// size it to match the text field
vSB.setSize(16, MyTextField._height);
// move it next to the text field
vSB.move(MyTextField._x + MyTextField._width, MyTextField._y);
The following code creates a horizontally oriented UIScrollBar instance and attaches it to the
bottom of a text field instance named MyTextField:
// createClassObject like any other component. Name it hSB.
_root.createClassObject(mx.controls.UIScrollBar, "hSB", 20);
hSB.horizontal = true
// set the target text field
hSB.setScrollTarget(MyTextField);
// size it to match the text field
hSB.setSize(MyTextField._width, 16);
// move it to the bottom of the text field
hSB.move(MyTextField._x, MyTextField._y + MyTextField._height);
