Using pygtk with gevent

[Arnau Sanchez]

Hi!

A recent thread brought up the question 'what do you use gevent for?':

http://groups.google.com/group/gevent/browse_thread/thread/4de9703e5dca8271

I' discovered gevent after some exploration (the usual way: asyncore,
twisted, concurrence, eventlet, ...) and I like it a lot. Now I intend
to use it to build a pygtk applicattion (target: Linux/Windows), but I
found no references.

Taking the "concurrent_download.py" example as an starting point, I
made this minimum demo code:

http://zaudera/public/gtkdown.py

It works, but I have some questions:

- Has anyone used gevent with pygtk?
- Is this the correct way of joining gevent jobs when you have another
events loop?
- Why a control+c does not quit the script as usual (after all jobs
have finished)? I have to control+z and kill the process manually.
Obviously, the app will do a clean "gtk.main_quit()", and this works,
but I am afraid this might be denoting some kind of issue with my
code.

thanks,

[Arnau Sanchez]

I've fixed it to make ctrl-c work (in the attachment). There's also
a way to exit the script after all jobs have finished, which is to spawn a new
job that will wait for the jobs and then call gtk.main_quit().

Let me know if there are other issues.

Cheers,
Denis.

Thanks, now it works perfect! I've added a gtk.Window with a button to test the
responsiveness and it runs smoothly.

Your code also gives me some hints about how to do it with eventlet, I am
testing both (eventlet has the advantage -when distributing- of being pure python).

thanks!
