The help page of int QMessageBox::exec() (https://doc.qt.io/qt-6/qmessagebox.html#exec) says: When using a QMessageBox with standard buttons, this function returns a StandardButton value indicating the standard button that was clicked. When using QMessageBox with custom buttons, this function returns an opaque value; use clickedButton() to determine which button was clicked.
