[Lazarus] Adding data field to a child node in a treeview

[Tony Whyman]

Susie,

You may find the code for TIBTreeView in the IBX for Lazarus package as 
a useful example of how to create a data aware treeview. Even you don't 
want to use IBX, the overall approach should work with other DB packages.
