ButtonBaseAccImpl is the accessibility implementation class
for spark.components.supportClasses.ButtonBase.
<p>Although ToggleButton, CheckBox, and RadioButton have their own
accessibility implementation subclasses,
Button simply uses the one for ButtonBase.
Therefore, the rest of this description refers to
the commonly-used Button component rather than the ButtonBase base class.</p>
<p>When a Spark Button 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 Button.
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 Button has no MSAA children.</p>
<p>
<b>Role</b>
</p>
<p>The MSAA Role of a Button is ROLE_SYSTEM_PUSHBUTTON.</p>
<p>
<b>Name</b>
</p>
<p>The MSAA Name of a Button is, by default, the label that it displays.
When wrapped in a FormItem element,
this label will be combined with the FormItem's label.
To override this behavior,
set the Button's <code>accessibilityName</code> property.</p>
<p>When the Name changes,
a Button dispatches the MSAA event EVENT_OBJECT_NAMECHANGE.</p>
<p>
<b>Description</b>
</p>
<p>The MSAA Description of a Button is, by default, the empty string,
but you can set the Button's <code>accessibilityDescription</code>
property.</p>
<p>
<b>State</b>
</p>
<p>The MSAA State of a Button 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 Button has focus)</li>
</ul>
</p>
<p>When the State changes,
a Button dispatches the MSAA event EVENT_OBJECT_STATECHANGE.</p>
<p>
<b>Value</b>
</p>
<p>A Button does not have an MSAA Value.</p>
<p>
<b>Location</b>
</p>
<p>The MSAA Location of a Button is its bounding rectangle.</p>
<p>
<b>Default Action</b>
</p>
<p>The MSAA DefaultAction of a Button is "Press".</p>
<p>When an MSAA client tells the Button to perform this action,
KEY_DOWN and KEY_UP MouseEvents for the SPACE key are generated,
to simulate pressing the ButtonBase via the keyboard,
if the Button is enabled.</p>
<p>
<b>Focus</b>
</p>
<p>A Button accepts focus.
When it does so, it dispatches the MSAA event EVENT_OBJECT_FOCUS.</p>
<p>
<b>Selection</b>
</p>
<p>A Button does not support selection in the MSAA sense.</p>

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