Welcome
HenkTrumpie,
Your phrasing and the directory suggest that this is more a Windows question that a Unix one, but in any case, I have a few to questions pose in response first:-
- Is this homework/assignment? There are specific forums for these.
- What have you tried so far?
- What output/errors do you get?
- What OS and version are you using?
- What are your preferred tools? (C, shell, perl, awk, etc.)
- What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly,
What have you tried so far?
There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.
We're all here to learn and getting the relevant information will help us all.
Kind regards,
Robin

NAME
POE::Loop::Tk - a bridge that allows POE to be driven by Tk
SYNOPSIS
See POE::Loop.
DESCRIPTION
POE::Loop::Tk implements the interface documented in POE::Loop. Therefore it has no documentation of its own. Please see POE::Loop for
more details.
POE::Loop::Tk is one of two versions of the Tk event loop bridge. The other, POE::Loop::TkActiveState accommodates behavior differences in
ActiveState's build of Tk. Both versions share common code in POE::Loop::TkCommon. POE::Loop::Tk dynamically selects the appropriate
bridge code based on the runtime environment.
SEE ALSO
POE, POE::Loop, Tk, POE::Loop::TkCommon, POE::Loop::PerlSignals.
