How to access the 3rd element (ComponentWidth) in QList

    QList<CComponent>* ComponentList = new QList<CComponent>();
    CComponent ComponentTemplate;
    while (xmlGet.findNextAndDescend("Component"))
    {

        QString ComponentID = xmlGet.getAttributeString("ID","unknown");
        QString ComponentType = xmlGet.getAttributeString("Type","unknown");
        int ComponentX = xmlGet.getAttributeInt("X");
        int ComponentY = xmlGet.getAttributeInt("Y");
        int ComponentWidth = xmlGet.getAttributeInt("Width");
        int ComponentHeight = xmlGet.getAttributeInt("Height");
        int ComponentZOrder = xmlGet.getAttributeInt("ZOrder");
        int ComponentAspectRatio = xmlGet.getAttributeInt("AspectRatio");

        ComponentTemplate.SetComponentID(ComponentID);
        ComponentTemplate.SetComponentType(ComponentType);
        ComponentTemplate.SetComponentX(ComponentX);
        ComponentTemplate.SetComponentY(ComponentY);
        ComponentTemplate.SetComponentWidth(ComponentWidth);
        ComponentTemplate.SetComponentHeight(ComponentHeight);
        ComponentTemplate.SetComponentZOrder(ComponentZOrder);
        ComponentTemplate.SetComponentAspectRatio(ComponentAspectRatio);
 
              if (xmlGet.findNext("Background"))
              {
                  int Transparent = xmlGet.getAttributeInt("Transparent");
                  int Red = xmlGet.getAttributeInt("Red");
                  int Green = xmlGet.getAttributeInt("Green");
                  int Blue = xmlGet.getAttributeInt("Blue");

                  ComponentTemplate.SetComponentBackgroundTransparent(Transparent);
                  ComponentTemplate.SetComponentBackgroundRed(Red);
                  ComponentTemplate.SetComponentBackgroundGreen(Green);
                  ComponentTemplate.SetComponentBackgroundBlue(Blue);
 
              }
             xmlGet.rise();
             ComponentList->push_back(ComponentTemplate); //how access 3rd element
 
    }

qDebug()<<ComponentList->at(2).GetComponentAspectRatio();

found the answer. It is tiring learning Qt API ...
