/** The AccessibleShape 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
::com::sun::star::drawing::XShape interface.
<p>The content of a draw page is modelled 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
AccessibleGraphicShape or AccessibleOLEShape.
See the section Children in the description of the
::com::sun::star::accessibility::XAccessibleContext
interface support for more details.</p>
<p>There are two services that extend this one: the
AccessibleGraphicShape and the
AccessibleOLEShape 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 ::com::sun::star::accessibility::AccessibleStateType::DEFUNC
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>

/** 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
com::sun::star::accessibility::AccessibleRole::SHAPE.</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 ::com::sun::star::text::AccessibleParagraphView for
details of how this text is represented.</li>
<li>Parent: The parent is either the document view as represented by
AccessibleDrawDocumentView 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>com::sun::star::accessibility::AccessibleStateType::DEFUNC
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
com::sun::star::accessibility::AccessibleStateType::DEFUNC
state set has already
been disposed and subsequent calls to this object result in
::com::sun::star::lang::DisposedException
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>com::sun::star::accessibility::AccessibleStateType::EDITABLE
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>
<li>com::sun::star::accessibility::AccessibleStateType::ENABLED
is always set.</li>
<li>com::sun::star::accessibility::AccessibleStateType::FOCUSABLE
is always set.</li>
<li>com::sun::star::accessibility::AccessibleStateType::FOCUSED
is set according to
whether the shape currently has the focus.</li>
<li>com::sun::star::accessibility::AccessibleStateType::MULTI_LINE
is set if a shape supports the
::com::sun::star::accessibility::XAccessibleText interface.</li>
<li>com::sun::star::accessibility::AccessibleStateType::OPAQUE
is set for certain shapes
with certain attributes like for a filled rectangle.</li>
<li>com::sun::star::accessibility::AccessibleStateType::RESIZABLE
is always set.</li>
<li>com::sun::star::accessibility::AccessibleStateType::SELECTABLE
is always set.</li>
<li>com::sun::star::accessibility::AccessibleStateType::SELECTED
is set according to
whether the shape is currently selected.</li>
<li>com::sun::star::accessibility::AccessibleStateType::SHOWING
is always set.</li>
<li>com::sun::star::accessibility::AccessibleStateType::VISIBLE
is always set.</li>

registered with a shape are informed of the usual events.</li>
