线程之间信号与槽通讯

mengruohen

我创建了两个线程，然后利用信号与槽函数进行两个线程之间的通讯，一个线程发送信号，另一个线程接收信号，但是槽函数接收不到信号！！
两个线程在主函数中已被初始化并启动start()了。
线程1:readthread

"readthread.h"
=============================
class readthread:public QThread
{
      Q_OBJECT
public:
      readthread();
      ~readthread();
      virtual void run();
signal:
      void signal_send_net(unsigned int);
}
=============================


readthread.cpp
=============================
readthread::readthread()
{
}
readthread::~readthread()
{
}
void readthread::run(）
{
      emit signal_send_net(12);
}
==============================

writethread.h
==============================
class writeThread:public QThread
{
   Q_OBJECT
public:
      writeThread();
      ~writeThread();
      virtual void run();
public slots:
      void slot_rcv_net(unsigned int);
private:
      readthread *rth;
}
================================

writethread.cpp
================================
writeThread::writeThread()
{
}
writeThread::~writeThread()
{
}
void writeThread::run()
{
      rth=new readthread();
      connect(rth,SIGNAL(signal_send_net(unsigned int)),this,SLOT(slot_rcv_net(unsigned int)));
}
void writeThread::slot_rcv_net(unsigned int net)
{
       qDebug()<<"net="<<net;
}
