hm, if you want to have a one-shot signal handler that will be executed when
your window is shown the first time, you would do:

gtk_signal_connect (GTK_OBJECT (window), "show",
                    GTK_SIGNAL_FUNC(my_handler), NULL);
static void
my_handler (GtkWindow *window, gpointer user_data)
{
  gtk_signal_disconnect_by_func (GTK_OBJECT (window),
                                 GTK_SIGNAL_FUNC (my_handler),
                                 user_data);
  /* place your code here */                                 
}
