Re: [g-a-devel] registering/deregistering event listeners

Steve,

Thanks for your reply, although I have to admit I find it troubling.
Yes, I am deregistering in the event handler.  It did not occur to me
that I should limit what I do in the event handlers.

Were you able to build a reliable application using an asynch approach?
Are you programming in C, Python, or some other language?

-Sam

Are you deregistering in the event handler?

I found that it best to do absolute minimum in the handers and call very
few functions. In the end I just put events in my own queue and dequeue
in idle processing - in other words make processing asynch.

I don't know what the official position is.
