Editing data from treeview

["Jorge Monsalvo" <jm_tecno2002 yahoo com ar>]

Hi,
        I need some ideas to continue my application because I'm stopped
with this problem. I have two treeviews in my application in different
windows. The first one has a Tree Model in 3 levels of depth. The second one
is a list store with the complete set of values for the last child of the
first tree. What I want is to click on the tree child and get the complete
set of values from the child selected and then open a new window where the
user can change them. I need to find a simple method to get the reference
value from the tree model, search the list store to get the right iter, pick
the values from the iter and call a new window using these values.
What I can imagine is (schematic) what follows, but I think it could be a
simplest way to do it. 

Can you help me??

Regards

        gchar   *name;
        gchar *searched;
        gchar *str_path;

        searched = (gchar *)data;
        gtk_tree_model_get(model, &iter, EQ_NAME, &name, -1);

I want)
