如何“检查”GtkCellRendererToggle？

// 创建GtkTreeViewColumn和GtkCellRendererToggle
GtkTreeViewColumn *column = gtk_tree_view_column_new();
GtkCellRenderer *renderer = gtk_cell_renderer_toggle_new();

// 将GtkCellRendererToggle添加到GtkTreeViewColumn
gtk_tree_view_column_pack_start(column, renderer, FALSE);
gtk_tree_view_column_set_attributes(column, renderer, "active", 0, NULL);

// 监听"toggled"信号
g_signal_connect(renderer, "toggled", G_CALLBACK(toggle_callback), data);

// 回调函数
void toggle_callback(GtkCellRendererToggle *renderer, gchar *path_str, gpointer data) {
    GtkTreeModel *model = (GtkTreeModel *)data;
    GtkTreePath *path = gtk_tree_path_new_from_string(path_str);
    GtkTreeIter iter;

    // 获取迭代器
    if (gtk_tree_model_get_iter(model, &iter, path)) {
        gboolean active;
        // 获取状态
        gtk_tree_model_get(model, &iter, 0, &active, -1);
        
        // 处理状态变化
        if (active) {
            // 执行操作
        } else {
            // 执行其他操作
        }
    }

    gtk_tree_path_free(path);
}
