#include <QProcess>

//方法一：直接執行shell命令

 //關機
void MainWindow::Shutdown()
{
    QProcess::execute("shutdown now");
}

//方法二：簡單的shell編輯器

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QDebug>
#include <QProcess>

    QMainWindow(parent),
    ui(new Ui::MainWindow)

    ui->setupUi(this);
    connect(ui->lineEdit,SIGNAL(returnPressed()),this,SLOT(on_pushButton_clicked()));
}

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

{
    QProcess process;
    process.start(ui->lineEdit->text());
    process.waitForFinished();
    QByteArray output = process.readAllStandardOutput();

    QString str_output = output;
