_accProps 269
To determine whether the player is running in an environment that supports accessibility aids, use
System.capabilities.hasAccessibility
.
The following table lists the name and data type of each
_accProps
property, its equivalent
setting in the Accessibility panel, and the kinds of objects to which the property can be applied.
The term
inverse logic means that the property setting is the inverse of the corresponding setting
in the Accessibility panel. For example, setting the
silent
property to
true
is equivalent to
deselecting the Make Movie Accessible or Make Object Accessible option.
To specify settings that correspond to the Tab index setting in the Accessibility panel, use the
Button.tabIndex
,
MovieClip.tabIndex
, or
TextField.tabIndex
property.
There is no way to specify an Auto Label setting at runtime.
When used without the
instanceName
parameter, changes made to
_accProps
properties apply
to the whole movie. For example, the following code sets the Accessibility
name
property for the
whole movie to the string
"Pet Store"
, and then calls
Accessibility.updateProperties()
to effect that change.
_accprops.name = "Pet Store";
Accessbility.updateProperties();
In contrast, the following code sets the
name
property for a movie clip with the instance name
price_mc
to the string
"Price"
:
price_mc._accProps.name = "Price";
Accessbility.updateProperties();
