Displaying a "hierarchy" of classes in a TreeView

[José Alburquerque <jaalburquerque cox net>]

Hi everyone.  I'm new to gtkmm though I think I understand the basics of 
gtkmm from the "Programming with gtkmm" tutorial.  However, I'm really 
stumped at implementing a TreeView.  As I understand it it needs a 
TreeModel both of which ListStore and TreeStore are.

For the project I'm developing I believe I'd need something like a 
TreeStore for the model because the rows in the intended TreeView will 
have children.  Here's my question:

I've developed a series of "hierarchical" classes (not in the sense of 
inheritance, but in the sense of one being a child of another, etc.) and 
the hierarchy can be somewhat intricate and moderately deep.

What I'm trying to do is display the hierarchy in a TreeView (by class 
name or a description of the class), but it's difficult for me to wrap 
my mind around what I need to do.  I notice that the TreeStore::create() 
method requires TreeModel::ColumnRecord, but what's confusing me is that 
my classes are not string classes so I don't know how I could represent 
them using the ColumnRecord.

Might any of you illuminate me a little as to how I might go about 
displaying my hierarchy of classes in a TreeView?  I'd really appreciate 
it.  Thanks.
