If you create a Dispatcher on a background thread, be sure to shut down the dispatcher before exiting the thread. This provides several ways to attach event handlers to objects. We will use a module called schedule. This dictionary is used to map a functions like func in the above example to a dispatcher object like Disptacher ('func'). The zope.event is a simple event system package. This is an implementation of the "Observer Pattern" with inspiration from the Kivy framework. The default group is 0. They're especially useful when many pieces of code may be interested in the same events. The dispatcher mechanism is particularly useful when constructing Model-View-Controller style applications where it is not desirable to have the Model objects aware of the event model. class asyncore.dispatcher¶ The dispatcher class is a thin wrapper around a low-level socket object. One missing use case is dispatching event in transaction.

"""Multiple-producer-multiple-consumer signal-dispatching dispatcher is the core of the PyDispatcher system, providing the primary API and the core logic for the system. In our example, wait_for_event_timeout() checks the event status without blocking indefinitely since timeout is given, e.wait(t). Daniele Esposti's Blog, in 31 July 2010 In this post I'll show you a simple event dispatcher implementation in Python. #!/usr/bin/env python import argparse import sys class FakeGit (object): def __init__ (self): parser = argparse.
