You can provide alternative names for the same toolkit. The decorated function should take a single argument, the IPython kernel instance, arrange for the event loop to call ``kernel.do_one_iteration()`` at least every ``kernel._poll_interval`` seconds, and start the event loop. :mod:`ipykernel.eventloops` provides and registers such functions for a few common event loops. csCxˆD]}ˆt|Sscs |ˆ_dS(sc@func.exit is now a decorator to register a function to be called on exit N(t exit_hook(t exit_func(tfunc(s3lib/python2.7/site-packages/ipykernel/eventloops.pytexit_decoratorUs(tloop_mapR/texit(R1tnameR2(t toolkitnames(R1s3lib/python2.7/site-packages/ipykernel/eventloops.pyt decoratorOs    ((R6R7((R6s3lib/python2.7/site-packages/ipykernel/eventloops.pytregister_integrationBs cCs t|_|jƒt|_dS(sðInner-loop for running the Qt eventloop Pulled from guisupport.start_event_loop in IPython < 5.2, since IPython 5.2 only checks `get_ipython().active_eventloop` is defined, rather than if the eventloop is actually running.
