Mustafa,
very nice!
I once had trouble removing a listener (because it had an anonymous
handler function); I wonder if your script would work then, too? Didn't
get in touch wih qx.event.Registration or qx.event.Manager up to now.
If this code works as intended, I'd vote for it to get into the
framework. Valuable!
Greetings,
Stefan

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
