Rozek: TkSocket_01 - UDP Communications Example with graphical User Interface

Andreas Rozek

TkSocket_01 - UDP Data Transfer under Tk

"TkSocket_01" represents the graphical counterpart of the "Socket_01" example and demonstrates the data transfer between UDP sockets. Main purpose of this program (as well as of the other TkSocket examples) is to test whether LuaSocket functions and Tk may be used together.

The source code is regular enough not to require any special explanation.

"TkSocket_01" should be invoked without any command line arguments

  lua TkSocket_01.lua

and (after having successfully passed all tests) presents itself as follows:
