[Fernando Alencar Maróstica <famarost unimep br>]

hello all !

I need delete one or severals rows on GtkTreeView depending
of action user. I use gtk+-2.0, libglade2, gnome2 !!

static void
remove_item (GtkButton *button, gpointer user_data)
{
        ???
}

int main (int argc, char *argv[]) {
        Marc21EditorGui *gui;
        GtkTreeModel *model;

        ...

        /* MY TREEVIEW WIDGET */
        model = create_model();

        gui->treeview = GTK_TREE_VIEW (glade_xml_get_widget (gui->xml,
        "treeview"));

        gtk_tree_view_set_model(gui->treeview, model);
        g_object_unref (G_OBJECT (model));

        gtk_tree_view_set_rules_hint (GTK_TREE_VIEW (gui->treeview),
         TRUE);
        gtk_tree_selection_set_mode (gtk_tree_view_get_selection
        (GTK_TREE_VIEW (gui->treeview)), GTK_SELECTION_MULTIPLE);

        add_columns (GTK_TREE_VIEW (gui->treeview));
        g_signal_connect (G_OBJECT (gui->treeview), "realize", 
        G_CALLBACK(gtk_tree_view_expand_all), NULL);


        /* MY DELETE BUTTON */
        gui->cmdRemoveItem = GTK_BUTTON (glade_xml_get_widget (gui->xml,
        "cmdRemoveItem"));

        g_signal_connect (G_OBJECT (gui->cmdRemoveItem), "clicked",
        G_CALLBACK(remove_item), gui->treeview);

        ...
}
