moveToThread的最简单用法（依葫芦画瓢即可）（使得线程也更偏向于信号槽的使用方法）

/*!* \file main.cpp** Copyright (C) 2010, dbzhang800* All rights reserved.**/#include <QtCore/QCoreApplication> #include <QtCore/QObject> #include <QtCore/QThread> #include <QtCore/QDebug>  class Dummy:public QObject {     Q_OBJECT public:     Dummy(QObject* parent=0):QObject(parent)     {} public slots:     void emitsig()     {         emit sig();     } signals:     void sig(); };  class Object:public QObject {     Q_OBJECT public:     Object(){} public slots:     void slot()     {         qDebug()<<"from thread slot:" <<QThread::currentThreadId();     } };  #include "main.moc"  int main(int argc, char *argv[]) {     QCoreApplication a(argc, argv);     qDebug()<<"main thread:"<<QThread::currentThreadId();     QThread thread;     Object obj;     Dummy dummy;     obj.moveToThread(&thread);     QObject::connect(&dummy, SIGNAL(sig()), &obj, SLOT(slot())); // 这里的slot()函数，相当于run()函数的作用    thread.start();     dummy.emitsig();     return a.exec(); }

结果：恩，slot确实不在主线程中运行（这么简单不值得欢呼么？）

main thread: 0x1a5c from thread slot: 0x186c
