POE::Loop::Tk \- a bridge that allows POE to be driven by Tk

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
POE::Loop::Tk replaces \s-1POE\s0's internal event loop with the Tk module.
This allows programs to use both \s-1POE\s0 and Tk at the same time.
.PP
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.
.PP
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 event loop bridge based on the runtime environment.
