FLASH CS3
User Guide
379
Each screen is automatically associated with ActionScript, based on its class. You can change the class to which
that screen is assigned, and you can set some parameters for a screen in the Property inspector.
To control screens with ActionScript, use the Screen class, Slide class, and Form class.
To create interactivity, use components whenever possible. Put no more than 125 total component instances in a
single FLA file.
To create navigation between slides, use
rootSlide
. For example, to get the current slide, use
rootSlide.currentSlide
.
Do not try to do slide navigation inside of
on(reveal)
or
on(hide)
handlers.
Do not add an
on(keydown)
or
on(keyup)
event to ActionScript code controlling a screen.
For more information on controlling screens with ActionScript, see “Screen class”, “Form class”, and “Slide class”, in
the
ActionScript 2.0 Components Language Reference
.
For information on the Object class and the
onclipEvent()
event handler, see Object and onClipEvent handlerin
ActionScript 2.0 Language Reference
.
To learn more about creating screen-based documents that use ActionScript, see "About organizing code for screens"
in
Using ActionScript 2.0 Components
.

Using components with screens
To create complex, structured applications in Flash, use components with screens. Components are especially useful
with forms to create structured applications that show data and enable nonlinear user interactivity. For example, use
forms to populate a container component.
To create custom navigation between components, use the Focus Manager when you use components with screens.
The Focus Manager specifies the order in which components receive focus when a user presses the Tab key to
navigate in an application. For example, customize a form application so that a user can press Tab to navigate fields
and press Return (Macintosh) or Enter (Windows) to submit the form.
For information on the Focus Manager, see “Creating custom focus navigation” in
Using ActionScript 2.0 Components
and “FocusManager class” in
ActionScript 2.0 Components Language Reference
.
You can also use the Accessibility panel to create a tab order.
