           Summary: AccessibleBase::accSelect is not implemented at all
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Accessibility
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mattc at serotek.com


Overview:
The accSelect method of the MSAA IAccessible interface is used by assistive
technologies to manage both the focus and (where applicable) the selection. 
The use of this method to manage the focus is especially important for screen
readers which usually implement an alternative user interface for navigating a
web page, often called a virtual buffer.  Specifically, the screen reader must
be able to programmatically set the focus to elements in the web page as the
user navigates.

Steps to reproduce (e.g. in a test program):
1.  Get an IAccessible object from WebKit using AccessibleObjectFromWindow.
2.  Call the accSelect method with SELFLAG_TAKEFOCUS as the first argument.
(SELFLAG_TAKEFOCUS is a constant in oleacc.h)

Actual result:
The method returns the E_NOTIMPL COM error.

Expected result:
This method should at least handle the SELFLAG_TAKEFOCUS flag.

Reproduced with r48199 on Windows XP.
