c - 如何获取 gtk.ListStore 的行数

Question

如何在C中获取gtk.ListStore的项目数/行数/长度/计数

这是我的示例代码:

  store = gtk_list_store_new (NUM_COLS, G_TYPE_STRING, G_TYPE_UINT);

  /* Append a row and fill in some data */
  gtk_list_store_append (store, &iter);
  gtk_list_store_set (store, &iter,
                      COL_NAME, "Heinz El-Mann",
                      COL_AGE, 51,
                      -1);

  /* .
     .
     .
  */
  /* get the length of gtk_list_store*/

使用gtk_tree_model_iter_n_children 获取列表存储中的行数。

在你的情况下

number_of_rows = gtk_tree_model_iter_n_children(GTK_TREE_MODEL(store), NULL);
