I am using gevent within PyQt4 applications and I am looking after the
best way to
integrate gevent and Qt.
I used to start a QTimer to run the gevent loop for a short period of
time every 10
milliseconds, interleaving Qt and gevent event loops in time ; it's a
very simple approach,
however it is not very efficient.
I tried other techniques like having 2 threads (one for each loop), or
in a greenlet, but I was not happy with it - in particular, when calling
processEvents() in a
greenlet, it doesn't play well with modal dialog boxes for example and I
Finally I decided to try to have a "PyQt backend" for gevent, ie. an
implementation of the
gevent loop using Qt constructs (QTimer, QSocketNotifier, etc.). I
didn't find any existing code
so I created a new project yesterday, here is the link to the github page:
I am happy to share it with you, hopefully it can be useful to someone else.
It seems to work for the basic tests I did - but it is far from being
complete at the moment.
Any help would be appreciated to make it better :)
