上面的代码有些啰嗦，同时记录了一些硬件的信息到dump文件中([http://blog.csdn.net/wangshubo1989/article/details/51855895][http_blog.csdn.net_wangshubo1989_article_details_51855895]);  
如果感觉没用，请自行忽略。

开始使用：  
在main.cc文件中：

首先定义一下回调：

#ifdef Q_OS_WIN
    long __stdcall   callback(_EXCEPTION_POINTERS*   excp)
    {
        CCrashStack crashStack(excp);
        QString sCrashInfo = crashStack.GetExceptionInfo();
    
        TCHAR my_documents[MAX_PATH];
        SHGetFolderPath(NULL, CSIDL_PERSONAL, NULL, SHGFP_TYPE_CURRENT, my_documents);
        QString file_path = QString::fromWCharArray(my_documents);
    
        QDir *folder_path = new QDir;
        bool exist = folder_path->exists(file_path.append("\\MyApp"));
        if(!exist)
        {
            folder_path->mkdir(file_path);
        }
        delete folder_path;
        folder_path = nullptr;
    
        QString sFileName = file_path + "\\crash.log";
    
        QFile file(sFileName);
        if (file.open(QIODevice::WriteOnly|QIODevice::Truncate))
        {
            file.write(sCrashInfo.toUtf8());
            file.close();
        }
    
        return   EXCEPTION_EXECUTE_HANDLER;
    }
    #endif

最后再main中添加：

#ifdef Q_OS_WIN
        SetUnhandledExceptionFilter(callback);
    #endif

关于SetUnhandledExceptionFilter不懂的地方可以参考：
