When a Spark Spinner is created,
its accessibilityImplementation property
is set to an instance of this class.
The Flash Player then uses this class to allow MSAA clients
such as screen readers to see and manipulate the Spinner.
See the mx.accessibility.AccImpl and
flash.accessibility.AccessibilityImplementation classes
for background information about accessibility implementation
classes and MSAA.
Children
A Spinner has 2 MSAA children, which are its increment and decrement buttons.
Role
The MSAA Role of a Spinner is ROLE_SYSTEM_SPINBUTTON.
The Role of each child button is ROLE_SYSTEM_PUSHBUTTON.
Name
The MSAA Name of a Spinner is, by default, an empty string.
When wrapped in a FormItem element, the Name is the FormItem's label.
To override this behavior,
set the Spinner's accessibilityName property.
The Name of each child button comes from a locale-dependent resource. For the en_US locale, the names are "More" and "Less".
When the Name of the Spinner or one of its child button changes, a Spinner dispatches the MSAA event EVENT_OBJECT_NAMECHANGE with the proper childID for the button or 0 for itself.
Description
The MSAA Description of a Spinner is, by default, an empty string,
but you can set the Spinner's accessibilityDescription
property.
The Description of each child button is the empty string.
State
The MSAA State of a Spinner is a combination of:
When the State of the Spinner or one of its child buttons changes, a Spinner dispatches the MSAA event EVENT_OBJECT_STATECHANGE with the proper childID for the button or 0 for itself.
Value
The MSAA Value of a Spinner is the value currently held by the Spinner.
The child buttons do not have MSAA values.
When the Value of the Spinner changes, a Spinner dispatches the MSAA event EVENT_OBJECT_VALUECHANGE.
Location
The MSAA Location of a Spinner, or one of its child buttons, is its bounding rectangle.
Default Action
A Spinner does not have an MSAA DefaultAction.
The DefaultAction of each child button is "Press".
Performing the default action of one of the child buttons will increment or decrement the value.
Focus
A Spinner accepts focus. When it does so, it dispatches the MSAA event EVENT_OBJECT_FOCUS event.
Selection
A Spinner does not support selection in the MSAA sense.
