### class spark.accessibility.TitleWindowAccImpl
This is the accessibility implementation class for spark.components.TitleWindow. When a Spark TitleWindow is created, the accessibilityImplementation property of its titleDisplay 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 this component. See the mx.accessibility.AccImpl and flash.accessibility.AccessibilityImplementation classes for background information about accessibility implementation classes and MSAA. The accessibility implementation extends the PanelAccImpl.
#### Children
A TitleWindow has no MSAA children. All children of the actual TitleWindow are siblings of the TitleWindow in the FlashPlayer's MSAA tree, because Flash Player does not support objects with accessibility implementations having children with their own accessibility implementations.
The TitleWindowAcImpll is set as the accessibilityImplementation of the titleDisplay object because setting it on the TitleWindow itself would not allow the TitleWindows's children to be exposed in MSAA. Because of this an invisible rectangle must be drawn in the titleDisplay making it the same size as the TitleWindow as a whole so 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 TitleWindow since the MSAA structure is flat.
#### Role
The MSAA Role of a TitleWindow is ROLE_SYSTEM_PANE.
#### Name
The MSAA Name of a TitleWindow is, by default, the title that it displays. To override this behavior, set the TitleWindow's accessibilityName property.
When the Name changes, a TitleWindow dispatches the MSAA event EVENT_OBJECT_NAMECHANGE.
#### Description
The MSAA Description of a TitleWindow is, by default, the empty string, but you can set the TitleWindows's accessibilityDescription property.
#### State
The MSAA State of a TitleWindow is always STATE_SYSTEM_MOVEABLE.
Since the State does not change, a TitleWindow does not dispatch the MSAA event EVENT_OBJECT_STATECHANGE.
#### Value
The MSAA Value of a TitleWindow is always the empty string.
#### Location
The MSAA Location of a TitleWindow is its bounding rectangle.
#### Default Action
The MSAA DefaultAction for a TitleWindow is the empty string.
#### Focus
A TitleWindow does not accept focus.
#### Selection
A TitleWindow does not support selection in the MSAA sense.
#### Other
A TitleWindow also dispatches the following MSAA events:
* EVENT_OBJECT_CREATE, when it is created
* EVENT_OBJECT_DESTROY, when it is closed
* EVENT_OBJECT_LOCATIONCHANGE, when it is moved
