a cross between a GtkTreeModel/Path and GtkList?

[Rick Jones <rick jones2 hp com>]

Hi -

As part of my attempts to make netperf4 easier to use, I'm starting down 
the path of writing a small GTK+2 application that will allow the user 
to create/edit netperf4 config files.  In a netperf4 config file, there 
are one or more "netservers" and a netserver can have 0 or more "tests" 
associated with it.

At first blush, after reading the Gtk+ 2.0 Tree View tutorial:

http://scentric.net/tutorial/treeview-tutorial.html

A GtkTreeModel/View seemed apropriate, but it would seem that the 
assumption is that while there is a parent/child relationship like my 
netserver/test, the parent and child have the same columns.

Is there a widget out there already, or some examples, where the child 
could have different columns from the parent?  Will I have to find a way 
to "nest" different GtkListModel/Views?

What I'd like to be able to do is allow the user to click on the expand 
gizmo (gee, does my knowledge of terms show?-) of a netserver and list 
the tests with their own column headings and such.

thanks for any pointers,

rick jones

an example of a netperf4 config file, with just one netserver, in its 
native XML form can be seen here:

or there is the DTD in all its present glory:
