Qt moveToThread

本文主要是介绍Qt moveToThread，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

注意，MyTask不能有父对象，否则线程不能转移，只能在父线程中执行。

#pragma once#include <QObject>
#include <QThread>
#include <QDebug>class MyTask : public QObject
{Q_OBJECTsignals:void sigResult(const QString &result);public slots:void slotDoing(const QString &val){qDebug() << "Worker thread id:" << this->thread()->currentThreadId();QString newVal;foreach (QChar c, val) {newVal.insert(0, c);}emit sigResult(newVal);QThread::sleep(3);}
};class Controller : public QObject
{Q_OBJECT
public:Controller(QObject *parent=0) : QObject(parent){qDebug() << "Controller thread id:" << this->thread()->currentThreadId();MyTask *task = new MyTask();task->moveToThread(&m_taskThread);connect(&m_taskThread, &QThread::finished, task, &QObject::deleteLater);connect(this, &Controller::sigStart, task, &MyTask::slotDoing);connect(task, &MyTask::sigResult, this, &Controller::slotResult);m_taskThread.start();}~Controller(){m_taskThread.quit();m_taskThread.wait(10000);qDebug() << "exit...";}signals:void sigStart(const QString &val);private slots:void slotResult(const QString &result){qDebug() << result;}private:QThread m_taskThread;
};
