I still only get this::

For-Loop():  main with tt = (0)
For-Loop():  main with tt = (1)

(leftJ:22024): Gtk-WARNING **: Attempting to add a widget with
type GtkBox to a GtkWindow, but as a GtkBin subclass a GtkWindow
can only contain one widget at a time; it already contains a
widget of type GtkBox
For-Loop():  main with tt = (2)

(leftJ:22024): Gtk-WARNING **: Attempting to add a widget with
type GtkBox to a GtkWindow, but as a GtkBin subclass a GtkWindow
can only contain one widget at a time; it already contains a
