Populating a Combo Box with Dynamic Data

Flash comes with a set of pre-built UI components for you to use in your

UI. The first widget you will create is a Flash MX Combo Box populated

with dynamic data that you will later link to a List Box. Here you will

populate an instance of the “Combo Box” component with data from our

sample database using RemoteCatalog.

A beginning set of Flash UI components comes bundled with Flash MX.

Newer sets of components (currently at 4) may be downloaded from the

Flash MX site at a later time.

Steps

1. Return to your RemoteCatalog.fla.

Adding a Flash MX Component to the Stage

2. Expand the Components panel. Click Window Æ Components if not

open already.

3. Select Flash UI Components.

4. Drag an instance of the ComboBox component just below the

Category List text on the stage. (Don’t worry about alignment or size

for now.)

5. Open the Properties panel for the ComboBox. Click Window Æ

Components if not open already.

6. Give the ComboBox an instance name of category_cb. This is the

instance variable you will use to refer to this visual component in your

code.

Populating the Component with Dynamic Data

7. Open the Actions panel for frame 1 of the Actions layer (press F9).

8. In the functions section, create a responder function that will receive

the returned data from the getCategories() call, as follows:

1 2 ... 6 7 8 9 10 11 12 13 14 15 16 17
