1、实现界面如下：

2、新建对话框窗口sDialog

3、设置ui格局如上图

4、将第三方类的文件加入项目中

5、将窗口配置文件的加入项目中

6、新建头文件如下：

#ifndef SDIALOG_H#define SDIALOG_H#include "qextSerialPort.h"#include "win_qextserialport.h"#include "comdialog.h"#include <QDialog>namespace Ui {class sDialog;}class sDialog : public QDialog{    Q_OBJECT    public:    explicit sDialog(QWidget *parent = 0);    ~sDialog();signals:                       void qtWin();    void closeWin();    private:    Ui::sDialog *ui;private:    QextSerialPort *myCom;              //使用第三方类定义对象    comDialog *comWin;                  //使用自定义串口配置类对象    bool isOpen;                        //判断串口是否被打开    bool isLogin;                       //判断是否登录系统    bool isClose;                       //判断是否关闭private slots:    void readMyCom();                   //读数据槽函数    void sendData();                    //发送数据槽函数    void comSetButton();                //串口配置槽函数    void disConnectMyComButton();       //断开连接槽函数    void scroll();                      //textBrowser光标移动槽函数protected:    void closeEvent(QCloseEvent *e);};#endif // SDIALOG_H

7、cpp源文件

 #include "sdialog.h"#include "ui_sdialog.h"#include "qextserialport.h"#include <QMessageBox>#include <QCloseEvent>sDialog::sDialog(QWidget *parent) :    QDialog(parent),    ui(new Ui::sDialog){    isLogin = false;    isOpen = false;    isClose = true;    ui->setupUi(this);    comWin = new comDialog;    ui->sendButton->setDefault(true);    ui->disConnectButton->setEnabled(false);    this->setWindowFlags(Qt::WindowCloseButtonHint);    this->setWindowFlags(Qt::WindowMaximizeButtonHint);    this->setWindowFlags(Qt::WindowMinMaxButtonsHint);    connect(ui->openButton,SIGNAL(clicked()),comWin,SLOT(exec()));              //打开串口配置对话框    connect(ui->connectButton,SIGNAL(clicked()),this,SLOT(comSetButton()));     //串口连接    connect(ui->sendButton,SIGNAL(clicked()),this,SLOT(sendData()));            //发送命令    connect(ui->textBrowser,SIGNAL(textChanged()),this,SLOT(scroll()));         //光标滚动    connect(ui->disConnectButton,SIGNAL(clicked()),this,SLOT(disConnectMyComButton())); //断开连接    connect(this,SIGNAL(qtWin()),this,SLOT(disConnectMyComButton()));                   //自定义信号断开连接    connect(this,SIGNAL(closeWin()),this,SLOT(accept()),Qt::QueuedConnection);          //使用排队方式连接信号emit语句后的代码将在发出信号后立即被执行}sDialog::~sDialog(){    delete ui;}//串口连接void sDialog::comSetButton(){    myCom = new QextSerialPort(comWin->comPort,QextSerialBase::EventDriven);    isOpen = myCom->open(QIODevice::ReadWrite);    if(isOpen == true)    {        QMessageBox::information(this,"infor",tr("open success!"));    }    else    {        QMessageBox::information(this,"infor","open failure!");        return;    }    ui->connectButton->setEnabled(false);    ui->openButton->setEnabled(false);    switch(comWin->comBaud)    {    case 0:        myCom->setBaudRate(BAUD300);        break;    case 1:        myCom->setBaudRate(BAUD600);        break;    case 2:        myCom->setBaudRate(BAUD1200);        break;    case 3:        myCom->setBaudRate(BAUD2400);        break;    case 4:        myCom->setBaudRate(BAUD9600);        break;

       break;    case 9:        myCom->setBaudRate(BAUD256000);        break;    }    switch(comWin->comStopBit)    {    case 0:        myCom->setStopBits(STOP_1);        break;    case 1:        myCom->setStopBits(STOP_1_5);
