Checkpoint 1.13 - Flash

Enable accessibility features of appropriate components

WCAG 1.0 Priority 2

WCAG Guideline 6. Ensure that pages featuring new technologies transform gracefully.

Flash MX 2004 and later versions have provided accessibility features for the following components:

  • Simple Button
  • Check Box
  • Radio Button
  • Label
  • Text Input
  • Text Area
  • Combo Box
  • List Box
  • Window
  • Alert
  • Data Grid

However these features are turned off by default and Flash developers are required to enable accessibility for each of these components individually.


Ensure accessibility features of relevant components are enabled.


Use the Action Script enableAccessibility() command for each of the components.


The following code is used to enable accessibility of a sample radio button:

   import mx.accessibility.RadioButtonAccImpl;

Checking Tool

Use Flash Player 6 or newer to browse Flash content and a screen reader to test its accessibility
