I haven't studied the code that deeply, but this part stands out to me as a
potential problem:
class MainWindow(QMainWindow):
...
for i in downloadLink:
self.t=DownloadTask(i)
self.downloadTaskList.append(downloadTaskInfo(fileName=self.t.fileName,
speed=self.t.speedRate,
progress=self.t.downloadPart ))
You are creating each download instance, assigning over the top of the last
attribute on your class, and then passing only the values to your model. I
would assume that your model is now getting static values that are not changing
as the download proceeds. You probably want to either take my previous
suggestion of having your download object manage a progress bar, or, pass in
the whole download instance object to your model so you can keep checking live
attributes that are changing.
Be aware that you are still using multiple QNetworkAccessManagers instead of
just one for your application
Hope that helps,
