c - if 语句用于树列表值？

Question

我将如何编写一个 if 语句来检查“COL_NUMBER”是否为“3”，这是我得到的代码:

gtk_list_store_append (store, &iter);
  gtk_list_store_set (store, &iter,
                      COL_NUMBER, 3,
                      -1);

renderer = gtk_cell_renderer_text_new ();
  gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (view),
                                               0,      
                                               "Number",  
                                               renderer,
                                               "text", COL_NUMBER,
                                               NULL);

要从树模型中获取值，请使用 gtk_tree_model_get ();
