View Full Version : Tutorial on threading in pyGTK

October 2nd, 2010, 06:03 AM
I'm creating an app with Quickly that uses OpenCV to detect faces via the OpenCv library which has to poll the camera constantly while GTK is doing it's thing so, I assume, it needs to be on a separate thread.

The final app should act very much like Cheese does, only using the OpenCv framework.

Threading is always a bit confusing to setup and I'm pretty new to python, so any links or info to go about doing this would be great. Thanks!

You can add callbacks to the event loop with gobject.timeout_add. No need for a separate thread unless one of your GTK callbacks is taking too long and even then they can sometimes be broken up.

Have a look at the section "20. The GTK Mainloop and Threading" of the PyGTK FAQ (http://faq.pygtk.org/index.py?req=index)

Wow, that was much simpler than I thought it was going to be. Thanks for the help!
