qt 要开启多个定时器

Posted 2023-04-07

参考技术A

//背景时12个帕尔贴 不要12个温度去曲线，每一个类似下图：

该类在线程启动12定时器计时，并停止，第13个定时器 定时读取温度
//头文件

class QThread;
class QTimer;

class ThreadTimer : public QObject

Q_OBJECT
public:
ThreadTimer();
~ThreadTimer();
public slots:
//index八连排索引， sec是秒 开启定时器
void StartTimer(int index, int sec );
void StartGetTem( int timeout );
void StopGetTem( );
private:
void GetTem();
signals:
void TimeOut(int index);
private:
virtual void timerEvent(QTimerEvent event);
private:
QTimer * m_pTimer;
QThread m_pCurrThread;
int m_nTimer[MAX_REAGENT];
;

//源文件

ThreadTimer::ThreadTimer()

memset(m_nTimer,0,sizeof(m_nTimer));
m_pCurrThread = new QThread;
m_pTimer = new QTimer(this);
connect(m_pTimer, &QTimer::timeout, this, &ThreadTimer::GetTem);
this->moveToThread(m_pCurrThread);
m_pCurrThread->start();

ThreadTimer::~ThreadTimer()

if( nullptr != m_pCurrThread)

m_pCurrThread->quit();
m_pCurrThread->wait();
m_pCurrThread->deleteLater();

void ThreadTimer::StartTimer(int index, int timeout )

m_nTimer[index] = startTimer( timeout* 1000);

void ThreadTimer::StartGetTem( int timeout )

m_pTimer->start( timeout*1000 );

void ThreadTimer::StopGetTem( )

m_pTimer->stop();

//计时任务
void ThreadTimer::timerEvent(QTimerEvent *event)

int timerID = event->timerId();
for( int i=0;i< MAX_REAGENT;i++)

if( timerID == m_nTimer[i])

m_nTimer[i] = -1;
emit TimeOut(i);
break;


qDebug()<<"ThreadTimer::timerEvent "<<QThread::currentThreadId()<<"\\n";
killTimer( timerID );

//获取温度
void ThreadTimer::GetTem()

真是奇怪，js可以，jq却开启了多个定时器，谁能解答一下

        timer = setInterval(mar,30);
        //鼠标移上去清除时钟
        box.onmouseover = function(event){
            clearInterval(timer);
            event.stopPropagation();
            //这里是阻止冒泡，不加要冒泡到body上面，鼠标在body上面就会clearInterval(timer);
            box.onmouseout = function(event){
                timer = setInterval(mar, 30);
             event.stopPropagation();
            }
        };
        //用jq方式写
        /*$(box).on(‘mouseover‘,function(){
            clearInterval(timer);
        })*/
//        $(box).mouseover(function(event){
//            clearInterval(timer);
//            event.stopPropagation();
//            $(box).mouseout(function(e){
//                timer = setInterval(mar,30);
//                e.stopPropagation();
//            })
//        });
