First as you said that and then I thought you needed to know about
GtkTreeModel widget

"The GtkTreeModel
<https://developer.gnome.org/gtk3/stable/GtkTreeModel.html> interface
defines a generic tree interface for use by the GtkTreeView
<https://developer.gnome.org/gtk3/stable/GtkTreeView.html> widget. It is an
abstract interface, and is designed to be usable with any appropriate data
structure. The programmer just has to implement this interface on their own
data type for it to be viewable by a GtkTreeView
<https://developer.gnome.org/gtk3/stable/GtkTreeView.html> widget."

for *bunches of those data, each in a different tab inside the same window.*

Second what you just said was different before that *You mean I should use
more than one GtkTreeModel for a *single* set of data?*

Finally, yes it's the same what I wanted you find in the Gtk document at
the first message from me to you.

*GtkTreeView can use more one GtkTreeModel* as the gtk_tree_view_set_model
function.
