Slightly technical question for my friends on Planet GNOME. I have been hunting around for some help online with no luck, so I figured I would post here and hopefully this blog entry can be a solution for those who have similar questions.
I am in the process of porting App Of Jaq to to async. To do this I am using
gio and have the code that downloads XML feeds up and running pretty well, and the app feels much more responsive. Now I need to have the application download an Ogg asynchronously without freezing the GUI.
My code currently looks like this:
def download_latest_shot(self): audiourl = "http://....the url to the Ogg file...." self.shot_stream = gio.File(audiourl) self.shot_stream.read_async(self.download_latest_shot_complete)
It then calls this callback:
def download_latest_shot_complete(self, gdaemonfile, result): f = self.shot_stream.read_finish(result).read() outputfile = open("/home/jono/Desktop/shot.ogg","w") outputfile.writelines(f)
Now, I am still pretty new to this, and while this code does work, it freezes the GUI pretty hard. Can anyone recommend some next steps for how I can download the file without it freezing? Some example code would be great. 🙂
Thanks in advance for anyone who can help. 🙂
