Screen instance names, class names, and
registration points (Flash Professional only)
The screen name automatically generates the instance name and class name of the screen. You
need these identifying labels 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, as described in the following list:
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
also update. For more information, see
(Flash Professional only)" on page
Symbol instances, including movie clips, buttons, and graphics, also have instance
names. For more information on symbol instances, see
Instances, and Library Assets," on page
The class name identifies the ActionScript class to which the screen is assigned. By default,
a slide screen is assigned to the
the
mx.screens.Form
methods and properties that are available for the screen. For more information on
ActionScript classes, see Chapter 7, "Classes" in Learning ActionScript 2.0 in Flash.
The Property inspector indicates the registration point in the x and y coordinate fields and
in the registration point grid. For more information, see
parameters for a screen (Flash Professional only)" on page
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.
