QT: 串口通信主站阻塞式实现

1.运行结果

2. 主程序调用

#include "dialog.h"

#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    Dialog dialog;
    dialog.show();
    return app.exec();
}

 3. 对话框类实现

//dialog.h

#ifndef DIALOG_H
#define DIALOG_H

#include "masterthread.h"

#include <QDialog>

QT_BEGIN_NAMESPACE

class QLabel;
class QLineEdit;
class QSpinBox;
class QPushButton;
class QComboBox;

QT_END_NAMESPACE

class Dialog : public QDialog
{
    Q_OBJECT

public:
    explicit Dialog(QWidget *parent = nullptr);
