自定义类的向量

我正在尝试创建我创建的自定义项目的向量，但我遇到了一个非常奇怪的问题。

当我创建类的实例时，我没有任何问题，但是当我尝试将其添加到向量时，我有一个很长的错误，我不知道该怎么做。

我不知道它是否有帮助，但m_mesureList是 PanneauMesure 类的私人属性。

.h 中的声明：

std::vector<Mesure> m_mesureList;

用：

void PanneauMesure::add(QPointF point1, QPointF point2, QPointF point3, QGraphicsItem *line1, QGraphicsItem *line2)
{
    Mesure mesure(point1, point2, point3, line1, line2, this);
    //m_mesureList.push_back(mesure);
}

错误：
