Pipeing to a Tk-Appby schweini (Friar)
|on Feb 17, 2003 at 04:54 UTC||Need Help??|
schweini has asked for the wisdom of the Perl Monks concerning the following question:
In this perl/Tk program i'm working on, i am opening a pipe to a simplistic, minimalistic "print-preview" Tk program:
... and some thime later i simply do some
print VIRTUALPRN "foobar\n"

here's the previewer:
