in class WorkerSignals(QObject):, we define progress = pyqtSignal(int).
in class MainWindow(QMainWindow): in def execute_this_fn(self, progress_callback):, we emit the signal progress_callback.emit(n*100/4).
However, n*100/4 is float. We must emit the correct type, i.e. int(n*100/4), or the signal will be converted to a random number.
