c++ - 没有类型的 Q_Object

Question

我收到的错误:

g++ -c -g -I/usr/lib/qt-3.3/include TCPEchoServer.cpp
Product.h:22: error: ISO C++ forbids declaration of âQ_Objectâ with no type
Product.h:24: error: expected â;â before âvoidâ
make: *** [TCPEchoServer.o] Error 1

我正在使用 QT 3.3。我错过了什么......？ T___T

#include <string>
#include <qtimer.h>
#include "HandleTCPClient.h"
#ifndef PRODUCT_H
#define PRODUCT_H
#include <qobject.h>
#include <qgl.h>

class Handler;

//Define ourselves a product class
class Product
    {

        Q_Object

        void startTimer();

    public:
        Product();

        string seller, itemName, description, highestBidder;
        double price, min, buyingPrice, currentBid;
        int time;
        bool isSold;
        Handler *handler;

        void setHandler(Handler *h);

    public slots:
        void setProductToSold();

    };

#endif

您错过了宏的正确大小写，它应该是 Q_OBJECT。
