How to get the GtkTreeStore from a GtkTreeView object

[Michele Bendazzoli <mickymouse mickymouse it>]

Hi all,

This is the first time I write in this list, I'm a novice with GTK 
library and linux development enviroment so excuse me if the questions I 
will ask are trivial.

I made a new  libglade project with anjuta, I design my interface  with 
glade and I'm  at the point I'm able to open a source file and display 
it in the first page of a GtkNoteBook, where I put my GtkTextView 
widget. I have also placed a button on bottom of my form to populate a 
GtkTreeView that I put on the second page of my notebook, to represent 
the flow chart of the source code that I have load in the source page.

I read the manual and I see that any GtkTreeView is alway associated 
with a model, i.e., for me, with a GtkTreeStore. I see also that in the 
examples they usually firstr create GtkTreeStore and then the TreeView 
from the GtkTreeStore, so that one can first populate the store and then 
render it with the GtkTreeView.

The problem for me is this: since I don't have to create the GtkTreeView 
because this seems to be automatically manage by the libglade middleware 
(I get the GtkTreeView directly by the xml made by glade), how can I get 
the store associated with the TreeView so that I can insert the row that 
I need?

Thank you in advance for any advice

ciao, Michele
