QT 启动并关闭外部程序 并传参_mozai147的博客

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

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}

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

void MainWindow::on_pushButton_clicked()
{
    QStringList arguments;//用于传参数
    QString program = "D:\SoftWare\MobileRobots\MobileSim\MobileSim.exe"; //外部程序地址
    arguments << "-m" << "D:\SoftWare\MobileRobots\Aria\maps\Map0.map" << "-r" <<"p3dx:robot1"<< "-r" <<"p3dx:robot2"<< "-r" <<"p3dx:robot3"; //程序需要传的参数 地图 机器人的数量
    QProcess process(this);
    process.startDetached(program, arguments);//启动程序
    //process.close();


   方法二
    QProcess *process = new QProcess(this);
    process->start(program, arguments);
    process->close();
