如何发送此的参考？ 我用MVC模式做C++的第一个项目。我有一个控制器类Session，它具有管理类ClientTsFrm（视图）的所有功能。我想做的是将所有发生的事件传递给view类。为此，我使用了观察者模式，实际上是这个实现

Session.h Session也是一个单例

#pragma once

#include "User.h"
#include "Config.h"

#include "../data/message.h"

#include <list>
#include <cstring>
#include <stdio.h>
#include <cstdlib> 
#include "../lib/eventtype.h"
#include "../lib/Subject.h"

#ifndef WX_PRECOMP
#include <wx/wx.h>
#include <wx/frame.h>
#else
#include <wx/wxprec.h>
#endif
#include <wx/richtext/richtextctrl.h>
#include <wx/grid.h>


typedef std::list<UserPTR> UserList;
typedef std::shared_ptr<UserList> UserListPTR;

/* 
 * Set and get functions
 */

class Session: public Subject<EventTS>{
public:
    static Session* Instance();
    private:
    Session();  // Private so that it can  not be called
    Session(Session const&){};             // copy constructor is private
    Session& operator=(Session const&){};  // assignment operator is private
    static Session* m_pInstance;
public:
private:
    Session* m_instance;
    ConfigPTR m_config;
    UserListPTR m_luser;
    char* m_translationEngine;
    MessageQueuePTR m_pending;
    MessageQueuePTR m_queue;
};

基本上，我正在注册ClientTSFrm对象。它存储在session类中，当事件发生时，session从subject类调用notify函数。此函数调用观察者clientsfrm的函数，观察者同时发送对象。最后，此函数调用ClientTSFrm类的函数以更新内容

如果我编译，它会显示以下错误：

错误28错误C2664:“void ClientTsFrm*”：无法转换参数 1从'ClientTsFrm'到'ClientTsFrm*'C:\Program Files x86\Microsoft Visual Studio 12.0\VC\include\functional 1149 1

试试std:：bindnotifyMSG，这个。太多的代码无法提供更多的帮助。@Bathsheba是的，它可以工作，但它不仅仅是这个的副本吗？？我想知道这一点，因为使用我的类的一个属性grid变量，程序崩溃了。记住KISS原则。@Daniel976034:这是一个指针，所以复制它会给同一个对象提供另一个指针，听起来像你想要的。绑定*正如您尝试的那样，这将复制对象，这可能不是您想要的；尤其是当函数需要指针而不是对象或引用时。崩溃意味着要么对象已被破坏，要么内存已损坏。你需要调试器来调查此事。@Cheersandhth.-Alf，有什么建议吗？MikeSeymour以及我可以使用什么函数来代替bind？
