c++ - 如何从Linux应用程序发送ifconfig？

我正在Linux上编写程序。我想阅读tabconfig中的ifconfig和屏幕。我不知道该怎么做。

我找到了this example。我想升级。



我有很多错误

        QMainWindow *window = new QMainWindow();

        window->setWindowTitle(QString::fromUtf8("MainWindow"));
        window->resize(480, 480);
        QWidget *centralWidget = new QWidget(window);
        QTabWidget *tabs = new QTabWidget(centralWidget);

        tabs->setFixedSize(440, 440);
        tabs->addTab(new QWidget(),"TAB 1");
        tabs->addTab(new QWidget(),"TAB 2");
        tabs->addTab(new QWidget(),"TAB 3");

tabs->tabBar()->setTabButton(2, QTabBar::LeftSide,((QWidget*)(button3)));
QProcess myProcess;
myprocess.start("ifconfig");
if (myProcess.waitForStarted(-1)) {

    while(ps.waitForReadyRead(-1)) {
        myTabWidget.setText(1, myprocess.readAllStandardOutput());
    }
}
window->setCentralWidget(centralWidget);


        window->setCentralWidget(centralWidget);
        window->show();

        return app.exec();

}

最佳答案

您正在寻找QProcess和/或QtNetwork将此信息添加到选项卡小部件中。

...
tabs->tabBar()->setTabButton(2, QTabBar::LeftSide,((QWidget*)(button3)));
QProcess myProcess;
myprocess.start("ifconfig");
if (myProcess.waitForStarted(-1)) {
    while(ps.waitForReadyRead(-1)) {
        myTabWidget.setText(your_index, myprocess.readAllStandardOutput());
    }
}
window->setCentralWidget(centralWidget);
...

话虽如此，您可以考虑将QtNetwork移植得更方便，因为“ ifconfig”在Windows上将无法运行，等等。您需要将其更改为ipconfig等。

为了公平起见，即使在Linux上，也应该查看“ ip”命令，而不要查看几乎没有维护的旧“ ifconfig”。

因此，您将使用适当的跨平台解决方案寻找QNetworkInterface和QHostAddress。这是一个简短的示例：

foreach(const QNetworkInterface &interface, QNetworkInterface::allInterfaces())
    qDebug() << interface.hardwareAddress();

foreach(const QHostAdress &address, QNetworkInterface::allAddresses())
    qDebug() << address.toString();
