[Glade-users] is there an example or tutorial about the use of 'GtkTreeStore' in the Glade?

B.) Ok. I guess that I understand...

in my case, the command make to appear in the main window (in scroll)
-----

treeview <- gtkBuilderGetObject( GUI, 'treeview_models' )
class( treeview )

model <- gtkTreeViewGetModel( treeview )
class( model )

gtkTreeStoreInsert( model, position=1 )

make more gain in this mail, I make an more question
in summary, I would like an  VISUAL structure like below.

How get this?

chem_models
|
|---pca_models ( VISIBLE by now )
|   |
|   |--- pca-1 (in future) insert elemnts in runtime
|   |--- pca-2 (in future) insert elemnts in runtime
|   |--- pca-n (in future) insert elemnts in runtime
|
|---hca_models ( VISIBLE by now)
|   |
|   |--- hca-1 (in future) insert elemnts in runtime
|   |--- hca-2 (in future) insert elemnts in runtime
|
|---pls_models ( VISIBLE   by now)
|   |
|   |--- (in future) insert elemnts in runtime
|


so, I my glade file I get the follow widget definitions:
( my run code in R )
