qt 定时器任务在多线程中执行
#include <QTimer>
#include <QMutex> //多线程
#include <QThread>
QThread* plantimer_thread = new QThread(this);
QTimer* plantimer = new QTimer();
plantimer->moveToThread(plantimer_thread);
plantimer->setInterval(1500);
//connect(plantimer_thread,&QThread::start, plantimer,&QTimer::start);//通过线程开启来触发定时器开启
connect(plantimer_thread, SIGNAL(started()), plantimer, SLOT(start()));//通过线程开启来触发定时器开启
connect(plantimer, &QTimer::timeout, this, &MainWindow::timerAutoSendSlots, Qt::DirectConnection);//信号发出后立即调用槽函数,槽函数在发出信号的线程中执行
connect(plantimer_thread, &QThread::finished, this, &QObject::deleteLater);//线程结束,自动关闭线程
plantimer_thread->start();
void MainWindow::timerAutoSendSlots()
{
qDebug() << QStringLiteral("当前线程id:") << QThread::currentThread();
