Regrettably, not free, but the Dream Tree subset of the Dream
Controls (it can be purchased separately) is excellent, and very
flexible. Here's an excerpt from the review I mentioned yesterday:
"Like Dream Memo, Dream Tree provides components which many
developers would find useful. It contains several TreeView and
ListView components, with extensions such as custom drawing,
multiple section, a "Treesource" architecture and database browsing
(with or without a hierarchical structure).
These tree components are widely used in the designer, for working
with projects and several property editors, such as the menu editor.
Custom Treesources can be developed for any data that has a
hierarchical structure. DC supplies a large number of TreeSources that
can be readily used, such as TDCMenuSource, TDCCollectionSource
and TDCResViewSource. Developing a custom TreeSource for specific
datastructure is easier and less work then developing a complete new
(derived) TTreeView.
The TDCDBTreeView component displays a database table with a tree
structure. The table should have two fields that define that structure: a
unique id field and a parentid field which references the id field of the
record's parent). Set the DataSource property and the table will be
shown in a tree-like manner. A similar result can be accomplished by
using TDCTreeView combined with TDCDatasetSource."
