QThread和windows 事件event一起使用,實現執行緒執行中休眠一定時間

class TestThread:public QThread
{
public:
    TestThread(QObject* parent = nullptr);
    virtual ~TestThread();
    void Stop();
protected:
    void run()  override;
    void FunOne();
    void FunTwo();
    void FunThree();

private:
    HANDLE h_event=nullptr;
    bool stoped = false;
};

TestThread::TestThread(QObject* parent):QThread(parent)
{
    h_event = CreateEvent(NULL, FALSE, FALSE, NULL);
}

TestThread::~TestThread()
{
    CloseHandle(h_event);
    if(h_event != nullptr)
    {
          h_event = nullptr;
    }

}

void TestThread::Stop()
{
    SetEvent(h_event);
    requestInterruption();
    stoped = true;
    quit();
    wait();
}

void TestThread::run()
{
    while(!QThread::currentThread()->isInterruptionRequested())
    {

        if(!stoped)
            FunOne();

        if(!stoped)
            FunTwo();

        if(!stoped)
             FunThree();
        if(WaitForSingleObject(h_event,1000) == WAIT_OBJECT_0)
        {
            break;
        }
        qDebug()<<"run";
    }
}

void TestThread::FunOne()
{
    WaitForSingleObject(h_event,1000);
    qDebug()<<"test one";
}

void TestThread::FunTwo()
{
    WaitForSingleObject(h_event,1000);
    qDebug()<<"test two";
}

void TestThread::FunThree()
{
    WaitForSingleObject(h_event,1000);
    qDebug()<<"test three";
}

Stop執行緒停止,也可以放在解構函式中完成。
