2. Treeitem and Treerow are only components that allowed to be item's children.
3. A new treerow should be constructed and append to item, when treerow of item is null.
   Otherwise, when treerow of item is not null, modify the content of the treerow or detach the treerow's children first, since that only one treerow is allowed
4. Do not append any treechildren to item in this method, a treechildren will be appended afterward.
5. When a treerow is not appended to item, generally label of item is displayed.
