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

See POE::Loop.

  use Tk;
  use POE;
  # Rest of your program here.

POE::Loop::Tk replaces POE's internal event loop with the Tk module. This allows programs to use both POE and Tk at the same time.

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 event loop bridge based on the runtime environment.

POE, POE::Loop, Tk, POE::Loop::TkCommon, POE::Loop::PerlSignals.
