Hello,
if I understand you correctly all you need is just to change the following line:
g_signal_connect (G_OBJECT (list->close_button), "clicked",
gtk_main_quit, NULL);
with this one:
g_signal_connect_swapped (list->close_button, "clicked",
gtk_widget_destroy, win);
Also you may not use gtk_main_quit() callback as your "delete-event"
handler, because it is supposed to terminate all application.
Some notes:
1. You can show all widgets in a container (with the container itself)
in one shot - just use gtk_widget_show_all().
2. You don't need to use G_OBJECT() cast in a first parameter to
signal connection functions.
