Qt错误 - 错误:不是信号或插槽声明

Question

我在QT尝试多线程服务器.但是,我不断收到这个恼人的错误:

错误:不是信号或插槽声明(第21行)

这是我的代码:

mythread.h

#ifndef MYTHREAD_H
#define MYTHREAD_H

#include <QThread>
#include <QTcpSocket>

class MyThread : public QThread
{
    Q_OBJECT
public:
    explicit MyThread(int ID, QObject *parent = 0);
    void run();
signals:
    void error(QTcpSocket::SocketError socketerror);

public slots:
    void readyRead();
    void disconnected();

public slots:
    QTcpSocket *socket;
    int socketDescriptor; //Socket ID Number

};

#endif // MYTHREAD_H

错误消息可以准确地告诉您问题所在.您将成员变量声明为插槽,但它们不是.我会改变你的课程如下:

class MyThread : public QThread
{
    Q_OBJECT
    [..]

private: // or public:
    QTcpSocket *socket;
    int socketDescriptor;
};
