RE: [gtk-list] Re: gtk_main() and foreign event loops

["Olivier Nenert" <onenert condumex com mx>]

Hi, I read your answer, I'm not using CORBA, but somthing similar, that also
requieres
regular "listening", and that is encapsulated enough not to let me give gtk
the sockets
directly. I was doing the trick with gtk_timeout_add and was wondering about
idle instead..
is idle better than timeout ?? (and why ?) I was somewhat thinking that the
"idle" wouldn't be "regular" enough, and that it would call the main_sniff
too often when having nothing better to do,
thus raising the cpu consuming sky high, and not calling it at all while
busy with anything else, thus
leting the app answer network events way too late. I was hoping the timeout
would be somewhat "fair" and would let the app have a regular behavior...
what do you think ???+
i didn't fnd much doc about it (I don't say there is not though, I just
didn't find it)
were my assumptions wrong ? any suggestion ??

thank you
cheers..

Olivier.
