That could be only possible if a vector layer (of the same resource) was 
added to the map and if the QueryOnClick widget was enhanced with a 
"AutoResourceActivation" tool, like the Shortcut widget.  Do you see 
what I mean ?

Unless there's a vector layer of the same resource, it would be 
impossible to "highlight" anything with a simple getfeatureinfo request...
