Using Accessible Components; Creating Accessibility With Actionscript - MACROMEDIA FLASH MX 2004-USING FLASH Use Manual

Using accessible components

To accelerate building accessible applications, Macromedia has built a core set of UI components.
These components automate many of the most common accessibility practices related to labeling,
keyboard access, and testing and help ensure a consistent user experience across rich applications.
Flash comes with the following set of accessible components:
•
SimpleButton
•
CheckBox
•
RadioButton
•
Label
•
TextInput
•
TextArea
•
ComboBox
•
ListBox
•
Window
•
Alert
•
DataGrid
Accessible Flash components have special requirements to work with screen readers. The
components must contain ActionScript that defines their accessible behavior. For information on
which accessible components work with screen readers, see the Macromedia Flash Accessibility
web page at www.macromedia.com/software/Flash/productinfo/accessibility/.
For general information about components, see Chapter 1, "About Components" in Using
Components.
For each accessible component, you enable the accessible portion of the component with the
enableAccessibility()
component as the document is compiled. Because there is no simple way to remove an object
after it has been added to the component, these options are disabled by default. Therefore, it's
important that you enable accessibility for each component. This step needs to be done only once
for each component; it is not necessary to enable accessibility for each instance of a component
for a given document. See "Button component", "CheckBox component", "ComboBox
component", "Label component", "List component", "RadioButton component", and "Window
component" in Using Components.

Creating accessibility with ActionScript

In addition to the accessibility features included in the Flash user interface, you can create
accessible documents with ActionScript. For accessibility properties that apply to the entire
document, you can create or modify a global variable called
ActionScript Language Reference.
