GtkTreeView: Simple application

["Felipe Balbi" <felipebalbi users sourceforge net>]

Hello all,

I'm starting an app to run Electrical Tests on the USB.
I'm not really good on GTK+ since I've always being developing on kernel-space.

my doubt regards this code:

int main(int argc, char *argv[])
{
        GladeXML        *openhset;
        GtkWidget       *main_window, *test_window;
        GtkWidget       *main_window_treeview1;
        GtkWidget       *main_window_ok;

        GtkListStore    *main_window_list;
        GtkTreeIter     iter;

        GtkCellRenderer *renderer;
        GtkTreeViewColumn       *column;

        struct usb_bus  *bus;

        gtk_init(&argc, &argv);

        /* Open the XML File */
        openhset = glade_xml_new (OPENHSET_XML, NULL, NULL);

        /* Get Widgets */
        main_window = glade_xml_get_widget (openhset, "main_window");
        main_window_ok = glade_xml_get_widget (openhset, "main_window_ok");
        main_window_treeview1 = glade_xml_get_widget (openhset,
"main_window_treeview1");

        /* Connect signal handlers */
        glade_xml_signal_autoconnect (openhset);

        /* Create a GtkListStore */
        main_window_list = gtk_list_store_new (1, G_TYPE_STRING);

        /* Populate the GtkListStore */
        gtk_list_store_append (main_window_list, &iter);
        gtk_list_store_set (main_window_list, &iter,
                        0, "TESTING",
                        -1);

        /* Add the GtkListStore to the GtkTreeView */
        gtk_tree_view_set_model (GTK_TREE_VIEW (main_window_treeview1),
GTK_TREE_MODEL (main_window_list));

        /* Renderer and column */
        renderer = gtk_cell_renderer_text_new();
        column = gtk_tree_view_column_new_with_attributes ("USB HCD", renderer,
                        "text", 1, NULL);

        gtk_tree_view_append_column (GTK_TREE_VIEW (main_window_treeview1), column);

        gtk_main();

        return 0;
}

So... I can't see the result of:

        gtk_list_store_set (main_window_list, &iter,
                        0, "TESTING",
                        -1);

It's not being listed in the treeview after building / running the code.

What am I doing wrong??
