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.
