1、工模GUI如下图：

　　注意两个API接口，_APP_Update_Layer()/UpdateNodeFunctionContent()

　　这两个接口一个是刷新ListView，另一个刷新ListView对应的TextBox值，后面简称ListView为工模的“键”，对应的TextBox为对应的“值”，即工模为键-值对的组合。

　　

　　1) 刷新ListView以及TextBox值

static   GUIResult_e _APP_Update_Layer(int NodeId){     GUIResult_e dRet = GUI_SUCCESS;    int i=0;    int ChildId = FactoryNode[NodeId].childID;    if(ChildId==0)        return dRet;    // 检查ListView页面节点数    int NextId =  FactoryNode[ChildId].nextID;    int count = 1;    while( (NextId!=0) && (count
     
      "，具体值由"UpdateNodeFunctionContent"刷新    for(i=0; i<=FM_ITEMS_PER_PAGE; i++)    {        HWND FocusItem_Handle;        dRet = GEL_GetHandle(pWindowControl, nItemStart+i, &FocusItem_Handle);        if(i
     

　　2）刷新菜单的Focus/Disable/Item滚动状态

static INT32 _APP_GUIOBJ_FM_FactorySetting_UpdateMenu(void){    GUIResult_e dRet = GUI_SUCCESS;    INT32 i32Index = 0;    UINT32 NodeId = ID_ROOT;    HWND hItem;    HWND hFocusItem;    State_e nState = NORMAL_STATE;    APP_Source_Type_t eSourceType = APP_SOURCE_MAX;    AL_ServiceDetail_t stServInfo;    AL_RecHandle_t hProgHdl;    UINT32 u32ColorSystem = 0;    APP_GUIOBJ_Source_GetCurrSource(&eSourceType);    //清除所有Item聚焦    for(i32Index=nItemStart; i32Index<=nItemEnd; i32Index++)    {        dRet = GEL_GetHandle(pWindowControl,i32Index, &hItem);        // Get state        GUI_FUNC_CALL( GEL_GetParam(hItem, PARAM_STATE,&nState) );        if(nState == FOCUS_STATE)        {            GUI_FUNC_CALL(GEL_SetAnimEnable(hItem, FALSE));            GUI_FUNC_CALL( GEL_SetParam(hItem, PARAM_SETNORMAL, NULL));        }    }    //设置特定Item的Disable状态    if(nowNodeHeadId == ID_FM_Funct_Backlight)    {        for(i32Index=0;(int)i32Index
     
      = u16preBacklightValue))                {                    dRet = GEL_SetParam(g_fmFactorySetting_data,PARAM_ITEM_DISABLE, (void*)&i32Index);                    dRet = GEL_GetHandle(pWindowControl, i32Index+nItemStart, &hItem);                    dRet = GEL_SetParam(hItem,PARAM_SETDISABLED, NULL);                }                else                {                    dRet = GEL_SetParam(g_fmFactorySetting_data,PARAM_ITEM_ENABLE, (void*)&i32Index);                    dRet = GEL_GetHandle(pWindowControl, i32Index+nItemStart, &hItem);                    dRet = GEL_SetParam(hItem,PARAM_SETNORMAL, NULL);                }                }            else            {                dRet = GEL_SetParam(g_fmFactorySetting_data,PARAM_ITEM_ENABLE, (void*)&i32Index);                dRet = GEL_GetHandle(pWindowControl, i32Index+nItemStart, &hItem);                dRet = GEL_SetParam(hItem,PARAM_SETNORMAL, NULL);            }        }    }    // 设置Item的聚焦及滚动    dRet = GEL_GetParam(g_fmFactorySetting_data, PARAM_CURRENT_INDEX, &i32Index);    dRet = GEL_SetParam(g_fmFactorySetting_data, PARAM_SETFOCUSED, NULL);    i32Index +=nItemStart;    dRet = GEL_GetHandle(pWindowControl, i32Index, &hFocusItem);    dRet = GEL_SetParam(hFocusItem, PARAM_SETFOCUSED, NULL);    GUI_FUNC_CALL(GEL_SetAnimEnable(hFocusItem, FALSE));     APP_GuiMgr_RegionBufferControl(&hFocusItem, 1); //设置滚动Item    GUI_FUNC_CALL(GEL_SetAnimEnable(hFocusItem, TRUE));     GUI_FUNC_CALL( GEL_ShowMenu(pWindow) );    GUI_FUNC_CALL(GEL_UpdateOSD());     return (UINT32)dRet;}
     

 　　3）菜单联动显示

　　　　即，当前聚焦的Item发生变化时，其它Item会联动变化，例如：工模调整背光百分比是，当前电流/占空比/PWM寄存器的值是应该跟随变化的

　　调用API:    UpdateNodeFunctionContent(ID_FM_Function_BlackLight_Backlight, 0, 0)

　　背灯例子：

void Factory_BackLight(BOOL bSet, BOOL path, FUNCTION_DATA *pValue, BOOL bDefault){    FUNCTION_DATA * FuncData = (FUNCTION_DATA *)pValue;        Backlight_t BacklightSetting;    BacklightSetting.Backlight_total_Stage = 100;        static char dutyBuff[10];    INT16 u16Pwm = 0;    UINT32 mapValue= 0;    if (bSet)    {        //调整Backlight(OSD)的值        u16Pwm= AL_FLASH_GetBackLight();        if (gbIsFMRightKey == TRUE)        {            u16Pwm = (++u16Pwm>=100)?100:u16Pwm;        }        else if (gbIsFMLeftKey == TRUE)        {            u16Pwm = (--u16Pwm<=0)?0:u16Pwm;        }        AL_FLASH_SetBackLight(u16Pwm);                BacklightSetting.OSD_backlight_index = u16Pwm;        //设置Backlight        Cmd_SetLcdBackLight(BacklightSetting);        mapValue = CONFIG_DEFAULT_PWM_REG_MAX - (CONFIG_DEFAULT_PWM_REG_MAX - CONFIG_DEFAULT_PWM_REG_MIN)*BacklightSetting.OSD_backlight_index / BacklightSetting.Backlight_total_Stage;        sprintf(dutyBuff,"%d - reg[%d]",u16Pwm,mapValue);        //Backlight 显示        Update_TypeVersion_Node(dutyBuff, FuncData->nItem);        MID_TVFE_GetCurrDutyPWM((short unsigned int *)&(u16DutyPWM));        //联动Item  Duty/Current/Duty Value 跟随变化，刷新包含Backlight后面的各个节点        UpdateNodeFunctionContent(ID_FM_Function_BlackLight_Backlight, 0, 0);    }    else    {        mapValue = CONFIG_DEFAULT_PWM_REG_MAX - (CONFIG_DEFAULT_PWM_REG_MAX - CONFIG_DEFAULT_PWM_REG_MIN)*AL_FLASH_GetBackLight() / BacklightSetting.Backlight_total_Stage;        sprintf(dutyBuff,"%d - reg[%d]",(INT32)AL_FLASH_GetBackLight(),mapValue);        Update_TypeVersion_Node((char * ) dutyBuff, FuncData->nItem);    }    }
