further study shows from

        @add_cat_btn.connect(SEL_COMMAND) {
            data = EntryData.new(ops_panel,"New Category")
            result = NameEntryDialog.new(data).execute
            unless result.zero?
                newname = data.value.value
                #Which item was selected from the tree...
                if treelist.currentItem
                    path = File.join(treelist.currentItem.full_path, Base36code.new($freelist.next).representation)
                    puts "item is #{treelist.currentItem.inspect}, children=#{treelist.currentItem.numChildren}"
                    @treeview[path] = treelist.addItemLast(treelist.currentItem, newname,
                    nil, nil, TreeData.new(treelist, path))
                    puts "item is #{treelist.currentItem.inspect}, children=#{treelist.currentItem.numChildren}"
                    treelist.recalc     # tell treelist it has changed...
                                        # Message-ID:
                                        # <3F3...@cf...>
                else
                    ; # raise "No item selected."
                end
            end
        }

I get

item is equipment, children=0
TreeData.new("/home/hgs/stores_loans/data/equipment/00b1bb0")
./stores_loans.rb:318:in `new'
./stores_loans.rb:318:in `initialize'

./stores_loans.rb:461
DirIndex.new("/home/hgs/stores_loans/data/equipment/00b1bb0" class:
String)
item is equipment, children=1
called catdialog.create()

Which shows that the number of children is now 1, rather than 0, but
none are displayed.
