R help - Apr 2011 - RGtk2: How to populate an GtkListStore data model?

hello all
I am trying to learn how to use the RGtk2 package...
so, my first problem is: I don't get the right way for populate my 
gtkListStore object!
any help is welcome... because I am trying several day to mount the code...
Thanks in advanced
Cleber N. Borges
---------------------------
# my testing code

library(RGtk2)
win <- gtkWindowNew()
datamodel <- gtkListStoreNew('gchararray')
treeview <- gtkTreeViewNew()
renderer <- gtkCellRendererText()
col_0 <- gtkTreeViewColumnNewWithAttributes(title="TitleXXX", 
cell=renderer, "text"="Bar")
nc_next <- gtkTreeViewInsertColumn(object=treeview, column=col_0, 
position=0)
gtkTreeViewSetModel( treeview, datamodel )
win$add( treeview ) # is there an alternative function for this?

# iter <- gtkTreeModelGetIterFirst( datamodel )[[2]]
# this function don't give VALID iter
# gtkListStoreIterIsValid( datamodel, iter )  result in FALSE
iter <- gtkListStoreInsert( datamodel, position=0 )[[2]]
gtkListStoreIterIsValid( datamodel, iter )

# the help of this function say to terminated in -1 value
# but -1 crash the R-pckage (or the gtk)...
gtkListStoreSet(object=datamodel, iter=iter, 0, "textFoo")
# don't make any difference in the window... :-(

Sorry about this. The help is autogenerated from the GTK+ C documentation.

It would be much easier to use rGtkDataFrame for populating this list. See
the help for that function.
