Qt widget for TFTP...
I found myself in the unusual situation of needing a class that wasn't already available in the Qt API. So I created one to implement the trivial file transfer protocol (TFTP) using the QUdpSocket class. Because of its size, I've posted it on my blog at: http://lau.engineering.uky.edu/2013/08/17/qt-based-tftp-class/ for anyone interested.
I have tried to understand your code but did nt have time to figure if it is the client side or the server side ?
This is the client.
Thanks a lot ...
