Declare a document class
When you use ActionScript 3.0, a SWF file may have a top-level class associated with it. This class is called the document class. When the SWF is loaded by Flash Player, an instance of this class is created to be the SWF file's top-level object. This object of a SWF file can be an instance of any custom class you choose.
For example, a SWF file that implements a calendar component can associate its top level with a Calendar class, with methods and properties appropriate to a calendar component. When the SWF is loaded, Flash Player creates it as an instance of this Calendar class.
- Deselect all objects on the Stage and in the Timeline by clicking a blank area of the Stage. This displays the Document properties in the Property inspector.
- Enter the path and filename of the ActionScript file for the class in the Document Class text box in the Property inspector.
Note: You can also enter the Document Class information
in the Publish Settings dialog box.
