scope="::com::sun::star::awt">XToolkit</type> 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 <member>XExtendedToolkit::getTopWindowCount</member> and
<member>XExtendedToolkit::getTopWindow</member> 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.
