怎样在Qt Runnable子类下编写信号和槽？

[weixin_38051170]

在QRunnable的子类MyRunnable中，怎样编写一个signal，使得这个signal与QTextBrowser的append方法连接？我写了一个，老是说，我的connect不匹配，求教啊！#ifndef MYRUNNABLE_H#define MYRUNNABLE_H#include <QRunnable>#include <QTcpSocket>#include <QTextBrowser>#include <QtCore>class MyRunnable : public QRunnable{    Q_OBJECTpublic:    explicit MyRunnable(QObject *parent = 0);    int SocketDescriptor;    void Initial(QTextBrowser*,int);    QTextBrowser *text;    QTcpSocket *socket;protected:    void run();    void Login();    void TimeLink();    void SendMessage();    void SiPin();signals:    void UpdateUi(QString);public slots:    };#endif // MYRUNNABLE_H#include "myrunnable.h"MyRunnable::MyRunnable(QObject *parent) :    QRunnable(){}void MyRunnable::Initial(QTextBrowser *text,int SocketDescriptor ){    this->text=text;    this->SocketDescriptor=SocketDescriptor;    connect(this,SIGNAL(UpdateUi(QString)),text,SLOT(append(QString)));}void MyRunnable::run(){    if(!SocketDescriptor){        qDebug()<<"!sock";        return;    }    else{        QTcpSocket socket;        socket.setSocketDescriptor(SocketDescriptor);        qDebug()<<"****************************\n";       // text->append("****************************");       // text->append("User:"+QString::number(SocketDescriptor));       // socket.r        //qDebug()<<socket.readAll();        //  socket.waitForReadyRead(3000);       //text->append(socket.readAll());       // text->append("****************************\n");       // socket.write("aaaaaaaaaaaaaaaaaaaaaaaaa");          emit UpdateUi("*************************");          emit UpdateUi("User:"+QString::number(SocketDescriptor));          socket.waitForReadyRead(3000);//        emit UpdateUi("User:"+QString::number(SocketDescriptor));          emit UpdateUi(socket.readAll());          emit UpdateUi("*************************");        socket.close();    }}报以下错误：..\MyServer\myrunnable.cpp:3:1: warning: unused parameter 'parent' [-Wunused-parameter]..\MyServer\myrunnable.cpp: In member function 'void MyRunnable::Initial(QTextBrowser*, int)':..\MyServer\myrunnable.cpp:12:70: error: invalid conversion from 'MyRunnable* const' to 'SOCKET {aka unsigned int}' [-fpermissive]..\MyServer\myrunnable.cpp:12:70: error: cannot convert 'const char*' to 'const sockaddr*' for argument '2' to 'int connect(SOCKET, const sockaddr*, int)'求教啊
