<p style="color: grey"> Python recipe 578634 by <a href="/recipes/users/4187487/">Justin Israel</a> (<a href="/recipes/tags/events/">events</a>, <a href="/recipes/tags/pyqt/">pyqt</a>, <a href="/recipes/tags/pyside/">pyside</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/thread/">thread</a>). Revision 4. </p> <p>A mechanism for communication from any thread to the main thread.</p> <p>It uses the same custom Event, but adds a classmethod convenience for taking a callback and params, wrapping it into an event and posting it to the receiver. Also adds in support for weak method references to the callback, in case the source object gets deleted before its callback is actually called.</p> <p>Merges forks of both: <a href="http://code.activestate.com/recipes/81253/#c5" rel="nofollow">http://code.activestate.com/recipes/81253/#c5</a> <a href="http://code.activestate.com/recipes/578299-pyqt-pyside-thread-safe-global-queue-main-loop-int/" rel="nofollow">http://code.activestate.com/recipes/578299-pyqt-pyside-thread-safe-global-queue-main-loop-int/</a></p>

Case</a> (<a href="/recipes/tags/events/">events</a>, <a href="/recipes/tags/qt4/">qt4</a>, <a href="/recipes/tags/signal/">signal</a>, <a href="/recipes/tags/slot/">slot</a>). </p> <p>I've modified the excellent <a href="http://code.activestate.com/recipes/576477-yet-another-signalslot-implementation-in-python/"><a href="http://code.activestate.com/recipes/576477/">recipe 576477</a></a> to allow for non method functions as well as method functions. This implementation also uses a WeakKeyDictionary instead of a WeakValueDictionary for reasons of code simplification/style.</p>

For instance you can build a pipeline to process web requests easily including some middleware for instance.</p>

I wanted to change it to suit my needs.</p> <p>Mostly I just wanted to add arbitrary functions and make the pipe line more list like in behavior.</p> <p>(edit: typos)</p>
