if __name__ == "__main__":
app,QtWidgets.QDialog =(QtWidgets.QApplication(sys.argv),Transfer_File())
QtWidgets.QDialog.show()
sys.exit(app.exec_())wahrscheinlich kann er kein self übergeben, zumindest denke ich mir das.
sobald er an dieser Zeile "def transferFinished(self,avg_speed): " kommt und die Funtion aufrufen will, kommt der Fehler.
in der stop() Funktion ist ja self.transferFinished.emit(self.avg_speed) also mit übergabe von self.avg_speed und nicht mit avg_speed
allerdings so:
Code: Alles auswählen
def stop(self):
avg_speed=self.avg_speed
self.is_running = False
self.abort = True
self.wait()
self.transferFinished.emit(avg_speed) ich hoffe einer weiss ein Rat
