XE6 c++builder 设置 font size GetPropInfo SetOrdProp

    TObject* objTemp;
    objTemp = GetObjectProperty(this, "Font");
    if (objTemp)
    {
        PPropInfo ppi;
        ppi = GetPropInfo(objTemp->ClassType(), "Size");
        if (ppi && (*ppi->PropType)->Kind == tkInteger)
            SetOrdProp(objTemp, ppi, 12);
    }

cb6要自己写函数GetObjectProperty，XE6里系统自带在Datasnap.Provider.hpp中定义了

TObject* GetObjectProperty(TObject *AObject, const String APropName)
{
    PPropInfo ppi;
    PTypeInfo pti;
    ppi = GetPropInfo(AObject->ClassType(), APropName);
    if (ppi && (*ppi->PropType)->Kind == tkClass)
        return GetObjectProp(AObject, ppi);
    return NULL;
}
