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.

sessions come and go.
