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）

#include <QtCore/QDebug> 

class Dummy:public QObject
{
    Q_OBJECT
public:
    Dummy(QObject* parent=):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
