The AccessibleChartDocumentView service is supported
by a Component that represents the view of a Chart document to
provide an entry point to the document tree for accessibility.
An object that implements the AccessibleChartDocumentView
service provides information about itself and about the chart
subcomponents contained in the chart document displayed in a
window. This service gives a simplified view on the underlying
implementation. It tries both to keep the structure of the
accessibility representation tree as simple as possible and
provide as much relevant information as possible.
Its name is the document's name or the base name of the filename if
no document name has been set explicitly.
Description
The description is the document's description or the
full filename if no description has been set
explicitly.
Children
The subcomponents of a chart. This includes all kinds of
titles, a legend and the diagram. The diagram and the legend are
the only children that themselves contain children. The Chart
subcomponents support the service
AccessibleChartElement . Additionally, there may be
shapes a user added via the clipboard. For details see the
drafts::com::sun::star::drawing::AccessibleShape .
Parent
The parent will usually be the window that contains the
Chart document view. It has to be set via implementation dependent
ways.
Relations
At the moment relations are not supported. The method
drafts::com::sun::star::accessibility::XAccessibleContext::getAccessibleRelationSet
will always return an empty set.
States
The following states are supported:
AccessibleStateType::DEFUNC
is set if a document view becomes obsolete like when
the window, which displays the view, is closed.
AccessibleStateType::ENABLED
is always set unless the
AccessibleStateType::DEFUNC
state is set.
AccessibleStateType::OPAQUE
is always set.
AccessibleStateType::SHOWING
is always set unless the
AccessibleStateType::DEFUNC
state is set.
AccessibleStateType::VISIBLE
is always set unless the
AccessibleStateType::DEFUNC
state is set.
Locale
Is the locale set at the document.
Property change listeners
They are supported to inform the
listeners about changes in this object.
Provide access to a Chart document's graphical representation.
The main purpose of this interface is to provide a bounding
box of the currently visible area and to let the user find the
subcomponents of a chart that cover a given test point.
