problem with GtkListStore

[<chenjun1 egr msu edu>]

Hi, dear all,

I plan to show a list inside a scrolled window. Everything is OK except
that the content of every row in the list is not shown. If I click the
row, it will turn color into blue. But I just can't see the content.

What's wrong? Below is part of the code related to list. Attached is the
whold .c files.

thanks & br

        GtkListStore *list_store;
        GtkWidget *tree;
        GtkTreeIter iter;
        list_store = gtk_list_store_new (1, G_TYPE_STRING);
        gtk_tree_view_set_model(GTK_TREE_VIEW(tree), GTK_TREE_MODEL(list_store));
        gtk_list_store_append (list_store, &iter);
        gtk_list_store_set(list_store, &iter, 0, "Foo", -1);
        gtk_list_store_append (list_store, &iter);
        gtk_list_store_set(list_store, &iter, 0, "Foo", -1);
        gtk_list_store_append (list_store, &iter);
        gtk_list_store_set(list_store, &iter, 0, "Foo", -1);
        
        tree = gtk_tree_view_new();     
        GtkCellRenderer *renderer;
        GtkTreeViewColumn *column;
        renderer = gtk_cell_renderer_text_new();
        column = gtk_tree_view_column_new_with_attributes("Name", renderer,NULL);
        gtk_tree_view_append_column(GTK_TREE_VIEW(tree), column);
        gtk_container_add (GTK_CONTAINER (scrolled_window2), tree);
        gtk_widget_show (tree);
