I am going on writing my video conference software. I wrote the video
grab, code/decode, and netwoark (multicast) transport.
I have one thread doing this:
for some times:
my_socket.recv() #blocking here
compute image #here we have a complete new image to display
Now, I was thinking to display the image in a Tk window. But I think
i will need a separate thread to run the mainloop() [thread 2], right?
How can I signale to the Tk thread that a new image is ready to be
shown? I was thinkin on using an event generated for the first
(network) thread. But I don't know how to do it exactly. Any
What if I access to Tk object form thread 1, is Tk thread safe?
