/** The XExtendedToolkit is an extension of the
    ::com::sun::star::awt::XToolkit interface.  It basically
    provides access to three event broadcasters which are used for instance
    in the context of accessibility.  It is, however, not restricted to
    accessibility.

    <p>The first event broadcaster lets you keep track of the open top-level
    windows (frames).  To get the set of currently open top-level window use
    the XExtendedToolkit::getTopWindowCount() and
    XExtendedToolkit::getTopWindow() methods.</p>

    <p>The second event broadcaster informs its listeners of key events.
    Its listeners can, unlike with most other broadcasters/listeners,
    consume events, so that other listeners will not be called for consumed
    events.</p>

    <p>The last event broadcaster sends events on focus changes of all
    elements that can have the input focus.</p>

    @deprecated
        This interface was only implemented in an intermediate developer
        release anyway.

    @since OOo 1.1.2
