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

# 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... :-(
