So all the uiobjects are in a flat structure array?  What if the set
of uiobjects is arranged in a tree structure, where one uiobject might
have other uiobjects as children?  Then I don't think the find trick
is enough.  In that case, wouldn't you need to search through the tree
recursively, looking at each set of children in the uiobject tree?
