Question

I have a QAction item that I initialize like follows:

QAction* action = foo->addAction(tr(\"Some Action\"));
connect(action, SIGNAL(triggered()), this, SL         


        

Answer 1

Without "this" context, e.g. from main():

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QLabel lbl{"Hello World!"};
    QPushButton btn;
    btn.show();
    lbl.show();

    QObject::connect(&btn, &QPushButton::clicked, [&lbl](){lbl.setText("Button clicked");});

    return a.exec();
}
