Introduction
Whether it's an input or dynamic text box, many people dread
the look of a disabled scrollbar. This tutorial will teach
you how to apply a simple code to make the scrollbar
invisible when it's not being used.

[ Type Enough Text to Make the Boxes Scroll ]
Steps to Create Animation
The following steps will help you to create the animation
you see above:
-
Create a new input box, name it
textBox, and change the line type to Multiline.
[ example of an image ]
-
Drag the scrollbar component onto the input
box; give the scrollbar an instance name of scroll1
and make sure the target text field is textBox.

-
Now, it's time to make the second text box, but this time
we're going to make it dynamic; with an instance
name of textBox2 and the line type set to
Multiline.

-
Repeat the process of adding a scrollbar. This time with
an instance name of scroll2 and a target text
field of textBox2
[ example of an image ]
-
The last design step: make a button--similar to the one
above, if you wish. And place it between the two text
boxes.
-
Now it's time to get our hands dirty with some
Actionscript. Add the following code to frame 1 (there
should only be one frame).
-
The final step is to add the following AS to the button.
Code Explanation
Set the text in the bottom text box (textBox2) equal to the text in the top text box (textBox).
textBox.maxscroll
A numeric text box property, that indicates the max value of the property scroll. If this value is 1, the associated scrollbar is disabled. If maxscroll is greater than 1, the scrollbar is enabled.
textBox.onChanged
An action that is called whenever the associated text box is modified.
The scrollbar component has been excluded from MX 2004, but the scrollbar component can be taken from any MX fla that includes the component:
