Finishing the scroll track The scroll track is already in place and its instance name is "scroll_track", right? Good! Now let's add the following code to our functions frame:
scroll_track.useHandCursor = false;
scroll_track.onPress = function () {
rec_y = _root._ymouse - this._parent._y;
if (rec_y > scroll_thumb._y) {
pressed = 5;
} else {
pressed = -5;
}
scrollIt();
checkIfPressed = setInterval(callBack, 500);
}
scroll_track.onRelease = scroll_track.onReleaseOutside = stopScroll;
One important thing to note here is that the number 5 in my code is one
less than the maximum number of lines that can be displayed in the text
field at one time. So if your text fields holds 20 lines, for example,
you would use 19 and -19 in your code instead. And that's about it!
On the next page, I'll have a summary of all the code we need, and where it should be.
