thanks, works fine.
just a little patch:
- gtk_widget_show() is'nt necessary
- assure that text widget is realized before setting background:

gdk_color_alloc(cmap, &color_black) ;
if(!GTK_WIDGET_REALIZED(text_field))
  gtk_widget_realize(text_field);
gdk_window_set_background (GTK_TEXT (text_field)->text_area, &color_black);
