hmmm.  the last two lines should grab the hscale value [i thought];
but nope::


void                     
scale_set_default_values (GtkScale *scale)
{
  gtk_range_set_update_policy (GTK_RANGE (scale), GTK_UPDATE_CONTINUOUS);
  gtk_scale_set_digits (scale, 0); // Zero digits after N.
  gtk_scale_set_value_pos (scale, GTK_POS_TOP);
  gtk_scale_set_draw_value (scale, TRUE);
    double  value = gtk_range_get_value(scale);
    fprintf(stdout,"hscale value: %g\n",value);
}

        i'll play around with gtk_adjustment_get_value() and see
        what it does.   i'm trying to follow that gespeaker does;
        but in C.  

        thanks,

        gary
