QT多线程moveToThread使用方式

#include "widget.h" #include "ui_widget.h" Widget::Widget(QWidget *parent) : QWidget(parent) , ui(new Ui::Widget) { ui->setupUi(this); childThreadTimer = new QTimer(this); parentThreadTimer = new QTimer(this); secondmethodTimer = new QTimer(this); connect(parentThreadTimer, &QTimer::timeout, this, &Widget::printTime); parentThreadTimer->start(1000); childthread = new QThread(); childthread->start(); mythread = new MyThread(); mythread->moveToThread(childthread); connect(childThreadTimer,&QTimer::timeout, mythread, &MyThread::mySlots); childThreadTimer->start(1000); secondthread = new QThread(); secondthread->start(); second = new sencondmethod(); second->moveToThread(secondthread); connect(secondmethodTimer, &QTimer::timeout,second, &sencondmethod::qDebugDateTime); secondmethodTimer->start(1000); } Widget::~Widget() { delete ui; } void Widget::printTime() { qDebug()<<"parent thread ID:" << QThread::currentThread()<<"current time" << QDateTime::currentDateTime().toString("yyyy-MM-dd hh:mm:ss"); }
