MACROMEDIA FLASH 8-ACTIONSCRIPT 2.0 LANGUAGE Reference page 1195

myTextField.onScroller = function (my_txt:TextField) {
trace (my_txt._name + " scrolled");
};
The
TextField.onScroller
Scroll bars typically have a thumb or other indicator that shows the current horizontal or
vertical scrolling position in a text field. Text fields can be navigated using the mouse and
keyboard, which causes the scroll position to change. The scroll bar code needs to be notified
if the scroll position changes because of such user interaction, which is what
TextField.onScroller
is called whether the scroll position changed because of a users interaction with
onScroller
the text field, or programmatic changes. The
interaction causes the change. These two options are necessary because often one piece of
code changes the scrolling position, while the scroll bar code is unrelated and won't know that
the scroll position changed without being notified.
