Folder icon in a hierarchical tree

Question

Hello, I don't know how can I put a folder icon in a hierarchical tree.
I have this query, and I know I have to change the 4th column, but I don't know how to do it.
SELECT -1,level,d_carpeta, null, id_carpeta
FROM DOCUMENTUM.doc_carpetas
START WITH id_carpeta_padre is null
CONNECT BY id_carpeta_padre = prior id_carpeta
and in the trigger (WHEN-TREE-NODE-SELECTED) I have this code
declare
htree ITEM;
n_selected NUMBER;
current_node FTREE.NODE;
begin
htree := Find_Item('blk_arbol_detalle.arb_carpetas');
n_selected := Ftree.Get_Tree_Property(htree, Ftree.SELECTION_COUNT);
FOR j IN 1..n_selected LOOP
current_node := Ftree.Get_Tree_Selection(htree, j);
if Ftree.Get_Tree_Node_Property(htree,
:SYSTEM.TRIGGER_NODE,Ftree.NODE_DEPTH) > 0 then
:blk_detalle.id_carpeta := Ftree.Get_Tree_Node_Property(htree,
:SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE);
else
:blk_detalle.id_carpeta := null;
end if;
END LOOP;
end;

Jesús,
just give it the name of an icon without the '.ico' extension. If you run it on the Web then the icon must be available in a gif format. Just the name nothing else. Make sure that in c/s the icon is in a directory mapped by the UI_ICON variable in of the Window Registry. For configuring icons on teh Web, have a look at this paper

If you need different folder icons on different tree levels, then instead of using a query, use a record group to populate the tree.
