Your message did give me some hints, but the GtkEntry failed to show up
in the GtkCList after I somewhat copied your codes to mine. I guess the
problem was due to the above "func(delay, x, y)", your message didn't
have the implementation of that 'func', so I commented it out in my code.
Could you show me the 'func'?
Thanks ;)
