如何在单击Qt4按钮时触发.sh文件或bash命令？

#include <QCoreApplication>
#include <QPushButton>
#include <QProcess>

class MyButton : public QPushButton
{
    Q_OBJECT
public:
    MyButton(QWidget *parent = nullptr) : QPushButton(parent) {
        connect(this, SIGNAL(clicked()), this, SLOT(onButtonClicked()));
    }

private slots:
    void onButtonClicked() {
        QProcess process;
        // 指定要执行的命令或.sh文件的路径和参数
        process.start("/path/to/command.sh");
        process.waitForFinished();
        // 如果你想获取命令的输出，可以使用以下代码
        QString output = process.readAllStandardOutput();
        // 处理输出结果...
    }
};

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    MyButton button;
    button.setText("Click me");
    button.show();

    return a.exec();
}

#include "main.moc"
