Rozek: TkSocket_02 - TCP Communications Example with graphical User Interface

Andreas Rozek

TkSocket_02 - TCP Data Transfer under Tk

"TkSocket_02" represents the graphical counterpart of the "Socket_02" example and demonstrates the data transfer between TCP 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_02" should be invoked without any command line arguments

  lua TkSocket_02.lua

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