Row selection in treestore

[Burcu Can <burcucana yahoo com>]

Hi, that's a part of my program. How can i provide the
third row (third element) to be selected instead of
first row at the beginning of the program? I used
gtk_tree_selection_select_iter(selection,&iter); 
function to make the selection but it doesn't work. 

enum
{
        COL_DIR=0,
        NUM_COLS
};

GtkWidget* create_view(GtkWidget* window)
{
        GtkWidget           *view;
    GtkTreeStore                *treestore;
    GtkTreeIter                  iter,child; 
        GtkCellRenderer     *renderer;
        GtkTreeSelection    *selection;
         
        view=lookup_widget(GTK_WIDGET(window), "treeview1");
                
        renderer = gtk_cell_renderer_text_new ();   
  
gtk_tree_view_insert_column_with_attributes(GTK_TREE_VIEW
(view),
                                               -1,    
 
                                              
"Directories",  
                                              
renderer,
                                               "text",
COL_DIR,
                                               NULL);
        treestore= gtk_tree_store_new(NUM_COLS ,
G_TYPE_STRING);
        gtk_tree_view_set_model(GTK_TREE_VIEW(view),
GTK_TREE_MODEL(treestore));
        g_object_unref(GTK_TREE_MODEL(treestore));      
        
        gtk_tree_store_append(treestore,&iter,NULL);
        gtk_tree_store_set (treestore, &iter,
                                                  COL_DIR,"mnt",
                                                  -1);
                                                  
    gtk_tree_store_append(treestore,&child,&iter);
        gtk_tree_store_set (treestore, &child,
                                                  COL_DIR,"cdrom",
                                                  -1);                                            
        
        gtk_tree_store_append(treestore,&iter,NULL);
        gtk_tree_store_set (treestore, &iter,
                                                  COL_DIR,"bin",
                                                  -1);
                                                 
        gtk_tree_store_append(treestore,&iter,NULL);
        gtk_tree_store_set (treestore, &iter,
                                                  COL_DIR,"usr",
                                                  -1);
                                                                                          

selection=gtk_tree_view_get_selection(GTK_TREE_VIEW(view));

    gtk_tree_selection_select_iter(selection,&iter);
                                                  
        return view;
}

Thanks...
