Accessibility class
Availability
Flash Player 6.
Description
The Accessibility class manages communication with screen readers. Screen readers are a type of
assistive technology for visually impaired users that provides an audio version of screen content.
The methods of the Accessibility class are static—that is, you don’t have to create an instance of
the class to use its methods.
To get and set accessible properties for a specific object, such as a button, movie clip, or text field,
use the
_accProps property. To determine whether the player is running in an environment that
supports accessibility aids, use
System.capabilities.hasAccessibility. For information on
creating accessible content, see “Accessibility overview” in Using Flash.
