This interface gives access to the three Header/Footer areas in the
page preview.
The parent returned by XAccessibleContext::getAccessibleParent
is the accessible spreadsheet page preview.
The children returned by
XAccessibleContext::getAccessibleChild all
support the interface
::com::sun::star::accessibility::XAccessibleXAccessible::getAccessibleContext for these children
returns an object that supports one of the following services.
::com::sun::star::text::AccessibleHeaderFooterView:
A child where calling XAccessibleContext::getAccessibleChild
an object that supports this service is returned for
every header and footer that is at least partially visible.
The following rules apply to the children order.
The first is the left area, than the centre area and the last
is the right area.
The description is ???.
The name is Header or Footer respectively.
The role is AccessibleRole::HEADER or
AccessibleRole::FOOTER.
There are no relations.
The following states are supported:
AccessibleStateType::DEFUNC is always false until
the preview is closed.
AccessibleStateType::EDITABLE is always false,
because the document is not editable in the page preview.
So it is left out of the list.
AccessibleStateType::ENABLED is always true.
AccessibleStateType::MULTILINE makes no sense on
a document and so it is left out of the list.
AccessibleStateType::MULTISELECTABLE is always
false, because in a page preview a selection is not
possible. So it is left out of the list.
AccessibleStateType::OPAQUE is always true.
AccessibleStateType::RESIZEABLE is always false,
because you can resize the window of the page preview, but
not the page preview itself. So it is left out of the
list.
AccessibleStateType::SELECTABLE is always false,
because in the page preview is no selection possible. So it
is left out of the list.
AccessibleStateType::SELECTED is always false,
because in the page preview is no selection possible. So it
is left out of the list.
AccessibleStateType::SHOWINGIs true if the
Bounding Box lies in the Bounding Box of the parent.
Otherwise it is false.
