Basemap Gallery Selection Listener

[MarkHoover]

Is there anyway to listen for a selection with the new basemap gallery dijit?  I would like to collapse the contentPane once a user has selected their basemap, but there do not seem to be any listeners for this, nor any properties to monitor.

Thanks,
Mark

Upon further review I was able to get the functionality I wanted via the listener for the map class "onLayerAddResult".  However, I still think it makes logical sense to add a "selectionChanged" listener to the Basemap Gallery dijit.
