Hi all. I'm trying to capture video from a webcam and then display the feed in a wxPython GUI. I originally borrowed code from the OpenCV wiki ([url]http://opencv.willowgarage.com/wiki/wxpython[/url]), and since the code was for OpenCV 1.x I tried to adapt it for version 2.1. Here's my attempt to far: [CODE]import …

Here's my situation. Let's say I would like to create a thread that continually prints the number 1. When a button is clicked the value should then change to 2. My issue is that I'm unsure how I change a variable in an already running thread. Here's my code: [CODE] …

wxWidgets does not support Python 3 (yet), so for me it's a deal breaker. I'm quite happy with Python 2.6, no need to switch to 3 at the moment.

Take a real close look at the threading examples on this page (absolutely brilliant tutorial): [url]http://www.blog.pythonlibrary.org/2010/05/22/wxpython-and-threads/[/url] I recently developed wxPython code (using the first example in the link above) which updates a clock in the GUI every one second, and break from the loop by setting a flag value as …

I was playing around with the same problem recently. The solution lies in threading. Basically you have a main loop and a secondary loop in a thread (for both the server and client). For example, the main loop can poll for received data whereas the threaded loop can wait for …

I really wish Python would be utilized more often, it is a really great language and has so much capability it's shocking. Sure, it's typically not as quick as C++ (heavy computation usually), but do we really care about the fastest execution times in everyday computing? Doubtful. I much prefer …
