How to get sender in static SLOT

[qtplus]

We can define static slots .

QMenu* getMenu(){
        QMenu* menu = new QMenu;
        auto action = menu->addAction("edit");
 
        QObject::connect(action,&QAction::triggered,onClicked);
 
        return menu;
    }
 
    Q_SLOT static void onClicked(){
        throw;
    }

QMenu* getMenu(){
        QMenu* menu = new QMenu;
        auto action = menu->addAction("edit");

        QObject::connect(action,&QAction::triggered,onClicked);

        return menu;
    }

    Q_SLOT static void onClicked(){
        throw;
    }
