可以响应 case WM_NOTIFICATION_CLICKED:  这里的程序可以执行，按键按下，会连续响应这个事件。
不能响应case WM_NOTIFICATION_RELEASED：这里的程序进不去，一直不能响应释放事件。
程序如下，请问怎么解决？？？？？？？？

static void _cbDialog(WM_MESSAGE * pMsg) {
  WM_HWIN hItem;
  int NCode, Id;
  // USER START (Optionally insert additional variables)
  // USER END

  switch (pMsg->MsgId) {
  case WM_INIT_DIALOG:

// Initialization of 'Button'
//
hItem = WM_GetDialogItem(pMsg->hWin, ID_BUTTON_0);
BUTTON_SetText(hItem, "HALT");
BUTTON_SetFont(hItem, GUI_FONT_20_ASCII);
BUTTON_SetFocussable(hItem,0);

//
// Initialization of 'Button'
//
hItem = WM_GetDialogItem(pMsg->hWin, ID_BUTTON_1);
BUTTON_SetText(hItem, "NEXT");
BUTTON_SetFont(hItem, GUI_FONT_20_ASCII);
BUTTON_SetFocussable(hItem,0);
//
// Initialization of 'Framewin'
//

hItem = pMsg->hWin;
FRAMEWIN_SetTextColor(hItem, GUI_MAKE_COLOR(0x00FF0000));
jason_FRAMEWIN = hItem;

// Initialization of 'Progbar'
//
jason_PROGBAR =WM_GetDialogItem(pMsg->hWin, ID_PROGBAR_0);
PROGBAR_SetFont(jason_PROGBAR, GUI_FONT_8X16_ASCII);
PROGBAR_SetMinMax(jason_PROGBAR, 0, 255);

// USER START (Optionally insert additional code for further widget initialization)

//BUTTON_SetReactOnLevel();
// USER END
break;
  // USER START (Optionally insert additional message handling)
  // USER END

  case  WM_NOTIFY_PARENT:
      Id = WM_GetId(pMsg->hWinSrc);
      NCode = pMsg->Data.v;
      switch(NCode)
      {
      case WM_NOTIFICATION_CLICKED:
            if(Id == ID_BUTTON_0)
            // prog_i = 0;
   SZ_STM32_LEDOn(LED1);
else if(Id == ID_BUTTON_1)
            // prog_i = 200;
               SZ_STM32_LEDOff(LED1);
            break;
case WM_NOTIFICATION_RELEASED:
      if(Id == ID_BUTTON_0)
               prog_i = 100;
else if(Id == ID_BUTTON_1)
               prog_i = 240;
   break;
      default:
            break;
      }

break;
  default:
WM_DefaultProc(pMsg);
break;
  }
}
