linux系统管理客户端1--串口配置代码编写

1、下载qextserialport-1.2win-alpha.zip

2、自定义串口配置类(comDialog：以备主界面调用) 3、UI需要自己定义

 

//自定义类的头文件：
////////////////////////////////////////////////////////////////////////

#ifndef COMDIALOG_H
#define COMDIALOG_H


#include 


namespace Ui {

class comDialog;

}


class comDialog : public QDialog

{

Q_OBJECT


public:

explicit comDialog(QWidget *parent = 0);

~comDialog();


private:

Ui::comDialog *ui;


private:

void getCom();                      //获取当前机器的可用端口函




private slots:

void clickCommitButton();         //确定按钮槽函数

void clickCancleButton();         //取消按钮槽函数


    void clickBackButton();              //恢复默认函数




public:


    QString comPort;

    int comBaud;

    int comStopBit;

    int comDataBit;

    int comPariy;

    int comFlow;

};

connect(ui->cancleButton,SIGNAL(clicked()),this,SLOT(clickCancleButton()));


    connect(ui->recoverButton,SIGNAL(clicked()),this,SLOT(clickBackButton()));

}


comDialog::~comDialog()

{

}



void comDialog::getCom()

{

for(int portCount = 1;portCount<17;i++)                 //听说COM口最多16

{

strCom += QString::number(portCount,10);

HANDLE Win_Handle =CreateFileA(strCom.toAscii(),GENERIC_READ|GENERIC_WRITE,0,NULL,OPEN_EXISTING,0,NULL);



if(Win_Handle != INVALID_HANDLE_VALUE)

{

ui->portcomboBox->addItem(strCom);

CloseHandle(Win_Handle);

}

}

}



//取消


void comDialog::clickCancleButton()

{

}



//确定

    comPariy = ui->paritycomboBox->currentIndex();

    comFlow = ui->flowCtrlcomboBox->currentIndex();

}



//恢复默认


   void comDialog::clickBackButton()

   {

   ui->stopBitcomboBox->setCurrentIndex(0);

   ui->dataBitcomboBox->setCurrentIndex(3);
