Screen instance names, class names, and registration points (Flash Professional only)

The screen name is used to automatically generate the instance name and class name of the screen. These identifying labels are needed when you manipulate screens with ActionScript in various ways. You can change a screen's registration point to adjust how the screen behaves. You can work with these features in various ways:

• The instance name is a unique name assigned to a screen, used when you target the screen in ActionScript. You can change the instance name in the Property inspector. The instance name is identical to the screen name in the Screen Outline pane and the linkage identifier for the screen. If you update the instance name, the screen name and the linkage identifier are also updated. See Setting properties and parameters for a screen (Flash Professional only).

  Note: Symbol instances, including movie clips, buttons, and graphics, also have instance names. For more information on symbol instances, see Using Symbols, Instances, and Library Assets.

• The class name identifies the ActionScript class to which the screen is assigned. By default, a slide screen is assigned to the mx.screens.Slide class, and a form screen is assigned to the mx.screens.Form class. You can assign the screen to a different class to modify the methods and properties available for the screen. For more information on ActionScript classes, see Creating Classes with ActionScript 2.0.
• The Property inspector indicates the registration point in the x and y coordinate fields and in the registration point grid. See Setting properties and parameters for a screen (Flash Professional only). You may want to move the registration point for greater control in manipulating screen content. For example, if you want to create a spinning shape in the center of a screen, you can reposition the screen registration point at the center of the screen and rotate the screen around its registration point.
