如何在QCheckBox中添加级联菜单

#include <QtWidgets>

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

    QMainWindow window;
    QWidget *widget = new QWidget(&window);
    QVBoxLayout *layout = new QVBoxLayout(widget);

    QCheckBox *checkBox = new QCheckBox("Check Box", widget);

    QMenu *menu = new QMenu(checkBox);
    QAction *action1 = new QAction("Action 1", menu);
    QAction *action2 = new QAction("Action 2", menu);

    menu->addAction(action1);
    menu->addAction(action2);
    checkBox->setMenu(menu);

    layout->addWidget(checkBox);
    widget->setLayout(layout);
    window.setCentralWidget(widget);
    window.show();

    QObject::connect(action1, &QAction::triggered, [](){
        qDebug() << "Action 1 triggered";
        // 处理 Action 1 相应的逻辑操作
    });

    QObject::connect(action2, &QAction::triggered, [](){
        qDebug() << "Action 2 triggered";
        // 处理 Action 2 相应的逻辑操作
    });

    return app.exec();
}
