When you first add a component to a document,
Flash imports it as a movie clip into the Library panel. You can
also drag a component from the Components panel directly to the
Library panel and then add an instance of it to the Stage. In any
case, you must add a component to the library before you can access
its class elements.
If you add a component to the library and create an instance
of it using ActionScript, you must first import its class with the
import
statement.
In the
import
statement, you must specify both
the component’s package name and its class name. For example, the
following statement imports the Button class:
import fl.controls.Button;
When you
place a component in the library, Flash also imports a folder of
its assets, which contain the skins for its different states. A
component’s
skins
comprise the collection of symbols that
make up its graphical display in the application. A single skin
is the graphical representation, or movie clip, that indicates a
particular state for the component.
The contents
of the Component Assets folder allow you to change the component’s
skins if you wish to do that. For more information, see
Customizing the UI Components
.
Once a component is in the library, you can add more instances
of it to your document by dragging its icon to the Stage from either
the Components panel or the Library panel.
