本文介绍了一个基于C++ Qt框架的WorkerThread类实现。该类继承自QThread，提供了线程启动、停止的方法，并在运行过程中输出当前线程ID。文章通过具体的代码示例展示了如何使用此类来创建和管理后台工作线程。

WorkerThread.h头文件

#ifndef WORKERTHREAD_H
#define WORKERTHREAD_H
#include <QThread>
#include <QDebug>
class WorkerThread : public QThread
{
    Q_OBJECT
public:
    WorkerThread(QObject* parent = NULL);
    ~WorkerThread();
    void startThread();
    void quitThread();
    void run();
protected:
    bool bQuitThread;
};

#endif // THREAD_H

WorkerThread.cpp源文件

#include "WorkerThread.h"

WorkerThread::WorkerThread(QObject* parent):QThread(parent),bQuitThread(false)
{

}
WorkerThread::~WorkerThread()
{
    quitThread();
}
void WorkerThread::startThread()
{
    if(!this->isRunning()){
        bQuitThread = false;
        this->start();
    }
}
void WorkerThread::quitThread()
{
    if(isRunning()){
        bQuitThread = true;
        this->wait();
    }
}
void WorkerThread::run()
{
    while (!bQuitThread) {
           qDebug() << "ThreadId =" <<currentThreadId();
           msleep(50);
    }
}
