&gt; do we have an enclosure for this?</span >

we don't in this class.

&gt;&gt; +    if (m_object-&gt;supportsExpanded() || m_object-&gt;isSummary())
&gt; 
&gt; should supportsExpanded() also include isSummary()?</span >

I think it's the detail element that actually has the expanded status. I'm not sure how other platform is doing this, so putting here to only affect mac.</pre>
