Using CAPI:tree-view without affecting display

I am displaying a tree-view and search it for items.  In order to find 
whether the item is in one of the children, I initially completely 
expand and collapse the tree so that CAPI becomes aware of all the items 
in the tree.

I would rather that the expanding and collapsing not be visible to the 
user.  Is there a way to do this "behind-the-scenes"?  Do I need to make 
a shadow tree-view and how would I do that so it isn't visible? Or do I 
need to create a new structure which represents the items and their 
position in the tree?

Do I need to make a shadow tree-view and how would I do that so it isn't visible? Or do I need to create a new structure which represents the items and their position in the tree? Can you not create a structure for your fully-expanded data and then just have a tree-view which just walks that structure? _______________________________________________ Lisp Hug - the mailing list for LispWorks users lisp-hug@lispworks.com http://www.lispworks.com/support/lisp-hug.html
