[提问]qt中输出语句 [复制链接]

请教高手，qt中输出语句应该怎么呢？
报错信息： 错误:C2039: “cout”: 不是“std”的成员
          错误:C2065: “cout”: 未声明的标识符
部分代码：void  CommandLineInterfaceManager::startTonemap()
{
    if (!saveLdrFilename.isEmpty())
  {
        VERBOSEPRINT("Tonemapping requested, saving to file %1.",saveLdrFilename);
        //now check if user wants to resize (create thread with either -2 or true original size as first argument in ctor, see options.cpp).
        //TODO
        tmopts->origxsize = HDR->getWidth();
        
                std::cout << "XSIZE: " << tmopts->xsize <<std::endl;
    
        if (tmopts->xsize == -2)    
            tmopts->xsize = HDR->getWidth();
    
                TMOThread *thread = TMOFactory::getTMOThread(tmopts->tmoperator, HDR, tmopts);
        connect(thread, SIGNAL(imageComputed(QImage*)), this, SLOT(tonemapTerminated(QImage*)));
    
    thread->startTonemapping();
    }
怎么改呢？万分感谢！

你包含相应的头文件了么？

题外：在Qt中，你可以考虑qDebug()

恩，原来输错一个字母。。。谢谢啦！
