run cmd in qt

[azys233]

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    // Create a Qt window
    QWidget window;
    window.setWindowTitle("Docker Container Operations");
    window.setGeometry(100, 100, 400, 200);

    // Create a text box to display output
    QTextEdit outputText(&window);
    outputText.setGeometry(50, 50, 300, 200);

    // Create a button to replicate the steps
    QPushButton runButton("Run Steps", &window);
    runButton.setGeometry(50, 300, 300, 30);

    // Connect the button click event
    QObject::connect(&runButton, &QPushButton::clicked, [&outputText]() {
        QProcess process;

        // Execute "docker exec" command
        process.start("docker exec -it xunxiao /bin/bash");
        process.waitForFinished();
        outputText.append(process.readAll());

        // Execute "conda activate" command
        process.start("conda activate xunxiao");
        process.waitForFinished();
        outputText.append(process.readAll());

        // Execute "cd" command
        process.start("cd /usr/app");
        process.waitForFinished();
        outputText.append(process.readAll());

        // Execute "python test.py" command
        process.start("python test.py");
        process.waitForFinished();
        outputText.append(process.readAll());

        // Execute "ls" command
        process.start("ls");
        process.waitForFinished();
        outputText.append(process.readAll());
    });

    window.show();

    return app.exec();
}

It doesn't work when I press the button, but I can run the command in cmd.

"It doesn't work" is not a good problem description. However, a self-contained program demonstrating the problem is always appreciated.

Reread the documentation for QProcess:start(). The program to be run and its arguments are separate. Something like this:

process.start(
  "/path/to/docker.exe", 
  QStringList() <<  "exec" << "-it" << "xunxiao" << "/bin/bash"
);

Your attempt to call CD will not work. CD is a Windows command shell builtin and there is no separate executable to run.

Your attempt to run ls seems doomed to fail on Windows.
