InfoTree is not one that I had tried, someone else listed
that one.

I have tried ElTree and had a crude data aware version
running.

I also have DBFlyTreeViewPro (www.imcasys.com) running with
an IBOQuery. This one does not maintain a complete tree,
only adding information as a branch is opened, and it works
very well like that - very fast on a large tree. It caused
me a problem as I can't open a branch when a fault is
detected in a sub-component as the information does not
exist, so I am back with VirtualTreeview and a complete
populated tree.

VirtualTreeview can be run without populating the
information in the branches, but I have not worked out yet
how to build the tree when there is no parent information
loaded in the tree - I may have the wrong database
structure, or I may have to modify the basic tree so that
the required information is available as the tree is built,
but the detail is not read until later. It seems to be a
number of compromises.
