错误：未找到需要右侧QUdpSocket的运算符

Question

Hello I use QT for developing I have this c++ code:

#include "udp.h"

udp::udp(QObject *parent) : QObject(parent)
{
   socket=new QUdpSocket(this);
   socket-> bind(QHostAddress::LocalHost,12345);
   connect(socket,SIGNAL(Readyread()),this ,SLOT(Readyread()));
}

This is example I just got from internet . well i get an error says:

error: C2679: binary '=' : no operator found which takes a right-hand operand of type 'QUdpSocket *' (or there is no acceptable conversion)

Please guide me how can I solve this error.

Answer 1

socket应声明为QUdpSocket* ，而不是QUdpSocket
