Widget      menu;
int         num_buttons;
WidgetList  buttons;

XtVaGetValues( simple_option_widget, XmNsubMenuId, &menu, NULL);

XtVaGetValues( menu, XmNnumChildren, &num_buttons,
        XmNchildren, &buttons, NULL ) ;

and change current selection with:

XtVaSetValues( simple_option_widget, XmNmenuHistory, buttons[index], NULL ) ;

/* where index is between 0 and num_buttons */
