/** The <type>AccessibleShape</type> service is implemented by UNO shapes to
provide accessibility information that describe the shape's features.
A UNO shape is any object that implements the <type
scope="::com::sun::star::drawing">XShape</type> interface.
<p>The content of a draw page is modeled as tree of accessible shapes
and accessible text paragraphs. The root of this (sub-)tree is the
accessible draw document view. An accessible shape implements either
this service or one of the "derived" services
<type>AccessibleGraphicShape</type> or <type>AccessibleOLEShape</type>.
See the section Children in the description of the
<type scope="::com::sun::star::accessibility"
>XAccessibleContext</type> interface support for more details.</p>
<p>There are two services that extend this one: the
<type>AccessibleGraphicShape</type> and the
<type>AccessibleOLEShape</type> services provide additional interfaces.
See there for details.</p>
<p>A shape object is either fully or partially visible on the screen or
has set the <const scope="::com::sun::star::accessibility"
>AccessibleStateType::DEFUNC</const> state to indicate that it is no longer
actively supported by its parent.</p>
<p>Each shape object that has not set the DEFUNC state has a valid
parent. That is either the containing draw page or a group shape or a
3D scene object.</p>

interface ::com::sun::star::accessibility::XAccessible;
/** Give access to the structural information of a shape.
<p>You can access the following information for the shape being made
accessible:
<ul>
<li>Role: The role of all shapes is <const
scope="com::sun::star::accessibility"
>AccessibleRole::SHAPE</const>.</li>
<li>Name: The name of a shape is its localized type name.</li>
<li>Description: Descriptions are localized and start with the
shape's type and style. After that follow some properties that
differ from the defaults with respect to the style.
<li>Children: The children of a shape are either other accessible
shapes or accessible text paragraphs. Only group shapes, 3D scene
shapes, and OLE shapes may contain other shapes as children.
Some of the shapes may have text paragraphs as (additional)
children. See <type scope="::com::sun::star::text"
>AccessibleParagraphView</type> for details of
how this text is represented.</li>
<li>Parent: The parent is either the document view as represented by
<type>AccessibleDrawDocumentView</type> or a group shape, 3D
scene shape, or OLE shape.</li>
<li>Relations: Are set and maintained from the outside. See the
service description of the object that has accessible shapes as
children for details.</li>
<li>States: The states supported by this service are:
<ul>
<li><p><const scope="com::sun::star::accessibility"
>AccessibleStateType::DEFUNC</const> is set if an accessible
shape is not visible but still existent for some reason.
This should not really happen and is a sign that someone,
e.g. an AT-Tool holds references to such a shape. The
reason for this is that either the owner of the accessible
shape did not remove it from its list of children or that
the AT-Tool does not care for the events indicating
this.</p>
<p>Usually an object that has the <const
scope="com::sun::star::accessibility"
>AccessibleStateType::DEFUNC</const> state set has already
been disposed and subsequent calls to this object result in
<type scope="::com::sun::star::lang">DisposedException</type>
exceptions.</p>
<p>If this state is set then no other of the states below is
set. This is also true for the states that are otherwise
always set (which makes "always" more of a sort of
"normally").</p></li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::EDITABLE</const></li> is always set.
This state is interpreted to mean that not only text but
also other, graphical, properties of a shape can be modified.
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::ENABLED</const> is always set.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::FOCUSABLE</const> is always set.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::FOCUSED</const> is set according to
whether the shape currently has the focus.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::MULTI_LINE</const> is set if a shape
supports the <type scope="::com::sun::star::accessibility"
>XAccessibleText</type> interface.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::OPAQUE</const> is set for certain shapes
with certain attributes like for a filled rectangle.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::RESIZABLE</const> is always set.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::SELECTABLE</const> is always set.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::SELECTED</const> is set according to
whether the shape is currently selected.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::SHOWING</const> is always set.</li>
<li><const scope="com::sun::star::accessibility"
>AccessibleStateType::VISIBLE</const> is always set.</li>
</ul>
<li>Locale: The shape returns the locale of its parent.</li>
<li>Property change listeners: Property change listeners that are
registered with a shape are informed of the usual events.</li>
