370 Chapter 17: Creating Accessible Content
For properties that apply to a specific object, you can use the syntax instancename._accProps.
The value of
_accProps is an object that can include any of the following properties:
Note: Inverse logic means that a value of true in ActionScript corresponds to a checkbox that is not
selected in the Accessibility panel, and a value of
false in ActionScript corresponds to a selected
check box in the Accessibility panel.
Modifying the _accProps variable has no effect by itself. You must also use the
Accessibility.updateProperties method to inform screen reader users of Flash content
changes. Calling the method causes Flash Player to re-examine all accessibility properties, update
property descriptions for the screen reader, and, if necessary, send events to the screen reader that
indicate changes have occurred.
When updating accessibility properties of multiple objects at once, you need to include only a
single call to
Accessiblity.updateProperties (too frequent updates to the screen reader can
cause some screen readers to become too verbose).
See
Accessibility.updateProperties() in Flash ActionScript Language Reference.
