Re: any ideas for a fix?

[Phil Wolff <adiabat centurylink net>]

You're trying to use each label in three places, and you can't do that.
Try this:

int
main (int argc, char *argv[])
{

  GtkWidget *window, *vbox;     // Labels go in here, vertically orientated.
  //GtkWidget *label1, *label2, *label3;
  GtkWidget *label1[32], *label2[32], *label3[32];
  int tt = 0;

  gtk_init (&argc, &argv);

  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_window_set_position (GTK_WINDOW (window), GTK_WIN_POS_CENTER);
  gtk_window_set_default_size (GTK_WINDOW (window), 700, 900);
  gtk_window_set_title (GTK_WINDOW (window), "Labels Left-Margins");
  gtk_container_set_border_width (GTK_CONTAINER (window), 10);
  g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL);

  for (tt = 0; tt < 3; tt++)
    {
      printf ("For-Loop():  main with tt = (%d)\n", tt);
      label1[tt] = gtk_label_new ("1: This is the file name named talk.1.txt");
      gtk_misc_set_alignment (GTK_MISC (label1[tt]), 0, 0.5);   // left
      label2[tt] = gtk_label_new ("2: This is talk.2.txt");
      gtk_misc_set_alignment (GTK_MISC (label2[tt]), 0, 0.5);   // left
      label3[tt] =
        gtk_label_new ("3: File talk.3.txt file.");
      gtk_misc_set_alignment (GTK_MISC (label3[tt]), 0, 0.5);   // left

      vbox = gtk_box_new (GTK_ORIENTATION_VERTICAL, 5); // GTK3
      gtk_container_add (GTK_CONTAINER (window), vbox);
      gtk_box_pack_start (GTK_BOX (vbox), label1[tt], FALSE, TRUE, 0);
      gtk_widget_show (label1[tt]);
      gtk_box_pack_start(GTK_BOX(vbox), label2[tt], FALSE, TRUE, 0);
      gtk_widget_show (label2[tt]);
      gtk_box_pack_start(GTK_BOX(vbox), label3[tt], FALSE, TRUE, 0);
      gtk_widget_show (label3[tt]);
      gtk_widget_show_all (window);
      gtk_widget_show_all (window);
    }

  gtk_main ();

  return 0;
}
