            Bug ID: 118418
           Summary: Should implemented scrollto, scrolltopoint,
                    scrollsubstringto, scrollsubstringtopoint
           Product: LibreOffice
           Version: 6.2.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: UI
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: samuel.thibault at ens-lyon.org

Description:
For better accessibility, libreoffice should implement the scroll*to*
accessibility calls, which allow the screen reader to fix what is shown, so
that a blind user and a sighted user can understand each other when they are
working together on a document.


Actual Results:
iaccessible2 and atspi scrollto calls have no effect

Expected Results:
iaccessible2 and atspi scrollto calls should scroll the document


Reproducible: Always


User Profile Reset: No



Additional Info:
More precisely, for instance winaccessibility/source/UAccCOM/MAccessible.cxx
reads:

STDMETHODIMP CMAccessible:: scrollTo(enum IA2ScrollType)
{
    return E_NOTIMPL;
}

It should support the requested scroll instead :)
(and similar for scrollToPoint, and in
winaccessibility/source/UAccCOM/AccTextBase.cxx for scrollSubstringTo and
scrollSubstringToPoint)

The code mentioned above is for Windows, Linux' atspi2 has just gotten scrollTo
and scrollToPoint in atk 2.29.1, and scrollSubstringTo and
scrollSubstringToPoint will probably be added before 2.30 too.
