Hi,
I just mentioned this problem with Qt4Agg and python 3.4 in another thread
[1], but I decided to post it on a thread of its own, as I suspect it might
be a bug in the Qt4Agg backend.
I get a NameError exception (see backtrace below) when trying to use key
events in matplotlib (master branch rev:
e322d5f5bb024bbec44d3ba76da1bc16bf52af9c), python 3.4.1, and pyqt 4.10.
Is this a bug?
Regards,
Jorge
