UG中MENUOPTION的初始化问题

lcfq

我设计了一个对话框，意图是：根据MENUOPTION1中的index来动态地设置MENUOPTION2中显示的内容。在编译时提示MENUOPTION2中的strings没有初始化。请教各位高手该如何解决？程序如下：
int TYPE_dalei_index_cb ( int dialog_id,
             void * client_data,
             UF_STYLER_item_value_type_p_t callback_data)
{
  UF_STYLER_item_value_type_t item1_data,item2_data;
  int index;
  char xiaolei_opt[6][20]={"a1","a2","a3","a4","a5","a6"};
  int row_num;
  row_num=2;
     /* Make sure User Function is available. */   
     if ( UF_initialize() != 0)  
          return ( UF_UI_CB_CONTINUE_DIALOG );
  
     /* ---- Enter your callback code here ----- */
  
   //get the index of the dalei option menu.
   item1_data.item_attr=UF_STYLER_VALUE;
   item1_data.item_id=TYPE_DALEI_OPTION;
   item1_data.indicator=UF_STYLER_INTEGER_VALUE;
   UF_STYLER_ask_value(dialog_id, [$item1_data)]
   index=item1_data.value.integer;
  
   //according to the index value to change the text of the xiaolei option menu.
   //item2_data.indicator=UF_STYLER_STRING_PTR_VALUE;
  
   item2_data.value.strings[0]=xiaolei_opt[0];
   item2_data.value.strings[1]=xiaolei_opt[1];
  
   if(index!=0)
   {
     if(index==1)
     {
       item2_data.value.strings[0]=xiaolei_opt[2];
       item2_data.value.strings[1]=xiaolei_opt[3];
     }
     else
     {
       item2_data.value.strings[0]=xiaolei_opt[4];
       item2_data.value.strings[1]=xiaolei_opt[5];
     }
   }
   item2_data.item_attr=UF_STYLER_SUBITEM_VALUES;
   item2_data.item_id=TYPE_XIAOLEI_OPTION;
   item2_data.count=row_num;
  
   UF_STYLER_set_value(dialog_id, [$item2_data)]
/*   else
   {
     item2_data.value.strings[0]=xiaolei_opt[0];
     item2_data.value.strings[1]=xiaolei_opt[1];
   }
*/
  
     UF_terminate ();
  
    /* Callback acknowledged, do not terminate dialog */
    return (UF_UI_CB_CONTINUE_DIALOG);  
    
    /* or Callback acknowledged, terminate dialog.    */
    /* return ( UF_UI_CB_EXIT_DIALOG );               */
  
}
编译提示：warning C4700: local variable 'item2_data' used without having been initialized。
