C++ 线程关联：无法为位于不同线程中的父级创建子级

我看到了一个，但我觉得我正在实现正确的模式，但我仍然无法完成它

嗯，我有一个Gui来启动和停止从串行端口的数据采集，并显示必要的通信消息。为了保持Gui的响应性，我将工作线程移动到一个线程。根据：和，我尝试实现线程关联。当我点击开始按钮时，我收到

QWinEventNotifier: event notifiers cannot be enabled from another thread
QWinEventNotifier: event notifiers cannot be enabled from another thread
QWinEventNotifier: event notifiers cannot be enabled from another thread
QObject: Cannot create children for a parent that is in a different thread.
(Parent is QSerialPort(0x142cd390), parent's thread is QThread(0x1259b070), current thread is QThread(0x142db1f0)

我错过了什么？以下是与我的问题相关的部分代码：

工人头

谢谢你的回答，我解决了我的问题。我在ComPort的构造函数中创建了一个串行端口，它在主线程中被调用。当cPort对象移动到cThread时，QSerialPort仍然将其线程关联设置为原始线程。解决方案是在ComPort:：setupPort中创建QSerialPort

#ifndef COMPORT_H
#define COMPORT_H

#include <QObject>
#include <QDebug>
#include <QSerialPort>

class QTimer;

class ComPort : public QObject
{
    Q_OBJECT

public:
    explicit ComPort(const QString &portName, QObject* parent = 0);
    ~ComPort();

private:
    QSerialPort*    port;
    QString         portMsg;
    QByteArray      responseData;
signals:
    void finished();

private slots:
    void onReadyRead();
    void setupPort();

};

#endif // COMPORT_H

#include "comport.h"

ComPort::ComPort(const QString &portName, QObject *parent)
    :QObject(parent)
{
    this->port = new QSerialPort(portName);
}

ComPort::~ComPort()
{
    port->close();
    delete port;
}

void ComPort::setupPort()
{
    port->setBaudRate(QSerialPort::Baud19200);
    port->setDataBits(QSerialPort::Data8);
    port->setFlowControl(QSerialPort::NoFlowControl);
    port->setParity(QSerialPort::NoParity);
    port->setStopBits(QSerialPort::OneStop);

    connect(port, SIGNAL(readyRead()), this, SLOT(onReadyRead()));

    *SOME CODE HERE*
}

void ComPort::onReadyRead()
{
    QByteArray bytes = port->readAll() ;
    qDebug() << "bytes:" << bytes <<"\n";
    responseData.append(bytes);
}

#include "gui.h"
#include "ui_gui.h"

gui::gui(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::gui)
{
    ui->setupUi(this);
    connect(ui->startButton, SIGNAL(clicked()), this, SLOT(OnstartButtonClicked()));
}

gui::~gui()
{
    delete ui;
}

void gui::OnstartButtonClicked()
{
    QThread*  cThread = new QThread;
    ComPort*  cPort   = new ComPort(QString("COM4"));
    cPort->moveToThread(cThread);
    connect(cPort, SIGNAL(finished()), cThread, SLOT(quit()));
    connect(cPort, SIGNAL(finished()), cPort, SLOT(deleteLater()));
    connect(cThread, SIGNAL(finished()), cThread, SLOT(deleteLater()));
    connect(cThread, SIGNAL(started()), cPort, SLOT(setupPort()));
    cThread->start();
}
