Let s start with the easy-peasy method: using the UIScrollBar component. We will talk about components in great depth in 11. For now, just work with us. In this particular case, no ActionScript is involved, which is why we re showing you the UIScrollBar component early. Components usually require a bit of programming.

It would be a really good idea, if you are using this component to use the Padding and/or Margins options in the Properties panel, to pull the text away from the edges of the component. Select the text on the stage, and check out how we did it in the Properties panel.
Rolling your own scroller
In this final exercise of the chapter, you are going to wire up a scroller using ActionScript. Just keep in mind that there are several hundred ways of doing this, and the method you are going to use is a very basic example of creating scroll buttons. In this example, you use a simple button created in Fireworks CS5 that has been converted to a movie clip. This button is found in the Library. In this example in which the whole process is managed by ActionScript, the text moves up or down a short distance (one line) with each mouse press. Others may have the text move up or down until the mouse is released. Regardless, the text is scrolling, which is the point of this exercise. Let s get busy:
1. Open the TLF_scrollable_AS.fla file in this chapter s Exercise folder. 2. Open the Library, and right-click the arrow movie clip. When the context menu opens, select
Properties to open the Symbol Properties dialog box.
TEXT
3. Twirl down the Advanced options, and select Export for ActionScript. The word arrow
should appear in the Class area. Click OK, and when Flash tells you there isn t such a thing as an arrow class, just click OK. By doing this, you have given the movie clip an instance name and let Flash know that it can be pulled out of the Library and used.
4. Select frame 1 of the actions layer, and open the Actions panel. Being the nice guys that we
are, we have entered the text that will appear in the container. Everything else, though, is up to you. Click once in line 1 of the Script pane, and enter the following code that creates the sprites that will hold the arrow movie clip in the Library: var upArrow:Sprite = new arrow(); var downArrow:Sprite = new arrow();
5. Next up you have to create the sprite that will hold the text container and put it on the stage. Click
at the end of the text string, press the Enter (Windows) or Return (Mac) key twice, and enter the following: var containerSprite: Sprite = new Sprite(); this.addChild(containerSprite); containerSprite.x = 25; containerSprite.y = 50;
6. Now that you have a sprite to hold the container, you need to put that container under the control
of the ContainerController class and to set the size of the container. Press the Enter (Windows) or Return (Mac) key twice, and enter the following: var container:ContainerController = new ContainerController(containerSprite,400,300);
7. Scrolling can be accomplished by having the text move up and down (vertically) or from side to
side (horizontally). You have to tell Flash that the text is to scroll vertically. Enter this line of code to accomplish that task: container.verticalScrollPolicy = ScrollPolicy.ON;
8. With the ScrollPolicy out of the way, the next task is to let the Configuration class take over
the management of the text in the container. Enter the following code: var config:Configuration = new Configuration(); var myEditManager :EditManager = new EditManager( new UndoManager());
The second line is optional but answers a question that may have occurred to you as you went through these exercises: how does TLF text controlled by ActionScript switch from Read Only to Selectable or Editable This line is how that task is accomplished.
