Can someone please tell me why I am getting the following error when I try to compile this?
有人能告诉我为什么当我试图编译它时，会得到以下错误吗?

void Add(EventData ev) {
this->aEvents.Add(ev);
}
This must be Add(EventData& ev). Your EventData class has no non-default copy constructor or copy assignment operator and has a member (CMap) that is non-copyable. This makes EventData non-copyable. So you can't pass it by value because that would have to make a copy, which you can't do since the class is non-copyable.
这必须添加(eventdata&ev)。您的EventData类没有非默认复制构造函数或复制赋值操作符，并且有一个不可复制的成员(CMap)。这使得EventData不可复制。所以你不能把它按值传递因为它需要复制，你不能这样做因为这个类是不可复制的。

CMap has default copy-ctor. Since CMap is derived from CObject and CObject's copy c-tor is private you get an error.
提出了copy-ctor违约。因为CMap是由CObject派生的，而CObject的副本c-tor是私有的，所以您会得到一个错误。

Instead of using CMap and CArray, I used std::map and std::vector since CString isn't compatible with CMap and CArray.
我没有使用CMap和CArray，而是使用std::map和std::vector，因为CString与CMap和CArray不兼容。
