PanelAccImpl is the accessibility implementation class
for spark.components.Panel.
<p>When a Spark Panel is created,
the <code>accessibilityImplementation</code> property
of a special child Sprite 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 Panel.
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 Panel has no MSAA children.
All children of the actual Panel are siblings of the Panel
in the FlashPlayer's MSAA tree, because Flash Player
does not support objects with accessibility implementations
having children with their own accessibility implementations.</p>
<p>The PanelAccImpl is set as the <code>accessibilityImplementation</code>
of the <code>titleDisplay</code> object because setting it on the Panel
itself would not allow the Panel's children to be exposed in MSAA.
Because of this an invisible rectangle is drawn in the
<code>titleDisplay</code> making it the same size as the Panel as a whole
so that the MSAA Location is the bounding rectangle of the entire Panel.
Screen readers like JAWS rely on the MSAA Location to announce whether
some component is in the grouping since the MSAA structure is flat.</p>
<p>
<b>Role</b>
</p>
<p>The MSAA Role of a Panel is ROLE_SYSTEM_GROUPING.</p>
<p>
<b>Name</b>
</p>
<p>The MSAA Name of a Panel is, by default, the title that it displays.
To override this behavior, set the Panel's <code>accessibilityName</code>
property.</p>
<p>When the Name changes,
a Panel dispatches the MSAA event EVENT_OBJECT_NAMECHANGE.</p>
<p>
<b>Description</b>
</p>
<p>The MSAA Description of a Panel is, by default, the empty string,
but you can set the Panel's <code>accessibilityDescription</code>
property.</p>
<p>
<b>State</b>
</p>
<p>The MSAA State of a Panel is always STATE_SYSTEM_NORMAL,
indicating that no state flags are set.</p>
<p>Since the state does not change,
a Panel does not dispatch the MSAA event EVENT_OBJECT_STATECHANGE.</p>
<p>
<b>Value</b>
</p>
<p>The MSAA Value of a Panel is always the empty string.</p>
<p>
<b>Location</b>
</p>
<p>The MSAA Location of a Panel is its bounding rectangle.</p>
<p>
<b>Default Action</b>
</p>
<p>A Panel does not have an MSAA DefaultAction .</p>
<p>
<b>Focus</b>
</p>
<p>A Panel does not accept focus.</p>
<p>
<b>Selection</b>
</p>
<p>A Panel does not support selection in the MSAA sense.</p>

Enables accessibility in the Panel class.
<p>This method is called by application startup code
that is autogenerated by the MXML compiler.
Afterwards, when instances of Panel are initialized,
the <code>accessibilityImplementation</code> property
of a special first child Sprite will be set to an instance
of this class.
If the PanelAccImpl were attached to the Panel itself
the accessibility implementations of the Panel's children
would be ignored.</p>
