SliderBaseAccImpl is the accessibility implementation class
for spark.components.supportClasses.SliderBase.
<p>The Spark HSlider and VSlider components extend SliderBase
and use SlideBaseAccImpl as their accessibility implementation
class.
For convenience, the rest of this description uses the word
Slider to mean either HSlider or VSlider, even though there
is no Spark class named Slider.</p>
<p>When a Slider is created,
its <code>accessibilityImplementation</code> 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 Slider.
See the mx.accessibility.AccImpl and
flash.accessibility.AccessibilityImplementation classes
for background information about accessibility implementation
classes and MSAA.</p>
<p>
<b>Children</b>
</p>
<p>A Slider has 3 MSAA children:
<ol>
<li>Clickable area to the left (or bottom) of thumb</li>
<li>Thumb</li>
<li>Clickable area to the right (or top) of thumb</li>
</ol>
</p>
<p>
<b>Role</b>
</p>
<p>The MSAA Role of a Slider is ROLE_SYSTEM_SLIDER.</p>
<p>The Role of each child is:
<ol>
<li>ROLE_SYSTEM_PUSHBUTTON</li>
<li>ROLE_SYSTEM_INDICATOR</li>
<li>ROLE_SYSTEM_PUSHBUTTON</li>
</ol>
</p>
<p>
<b>Name</b>
</p>
<p>The MSAA Name of a Slider 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 Slider's <code>accessibilityName</code> property.</p>
<p>The Name of each child comes from a locale-dependent resource.
In the en_US locale, the names are:
<ol>
<li>"Page left" for HSlider; "Page up" for VSlider</li>
<li>"Position"</li>
<li>"Page right" for HSlider; "Page down" for VSlider</li>
</ol>
</p>
<p>When the Name of the Slider or one of its child parts changes,
a Slider dispatches the MSAA event EVENT_OBJECT_NAMECHANGE
with the proper childID for the part or 0 for itself.</p>
<p>
<b>Description</b>
</p>
<p>The MSAA Description of a Slider is, by default, the empty string,
but you can set the Slider's <code>accessibilityDescription</code>
property.</p>
<p>The Description of each child part is the empty string.</p>
<p>
<b>State</b>
</p>
<p>The MSAA state of a Slider is a combination of:
<ul>
<li>STATE_SYSTEM_UNAVAILABLE (when enabled is false)</li>
<li>STATE_SYSTEM_FOCUSABLE (when enabled is true)</li>
<li>STATE_SYSTEM_FOCUSED
(when enabled is true and the Slider has focus)</li>
</ul>
</p>
<p>The State of each child part is:
<ul>
<li>STATE_SYSTEM_UNAVAILABLE (when enabled is false)</li>
</ul>
</p>
<p>When the State of the Slider or one of its child parts changes,
a Slider dispatches the MSAA event EVENT_OBJECT_STATECHANGE
with the proper childID for the part or 0 for itself.</p>
<p>
<b>Value</b>
</p>
<p>The MSAA Value of a Slider is a number between 0 and 100.</p>
<p>The child parts do not have MSAA values.</p>
<p>When the Value of the Slider changes,
a Slider dispatches the MSAA event EVENT_OBJECT_VALUECHANGE.</p>
<p>
<b>Location</b>
</p>
<p>The MSAA Location of a Slider or its thumb is its bounding rectangle.
For the two children representing the trackbar regions adjacent
to the thumb, the slider's bounding rectangle is returned.</p>
<p>
<b>Default Action</b>
</p>
<p>A Slider and its child parts have no default action.</p>
<p>
<b>Focus</b>
</p>
<p>A Slider accepts focus.
When it does so, it dispatches the MSAA event EVENT_OBJECT_FOCUS.</p>
<p>
<b>Selection</b>
</p>
<p>A Slider does not support selection in the MSAA sense.</p>

Enables accessibility in the SliderBase class.
<p>This method is called by application startup code
that is autogenerated by the MXML compiler.
Afterwards, when instances of sliders are initialized,
their <code>accessibilityImplementation</code> property
will be set to an instance of this class.</p>
