Qt fixes

Hi all,

Denis Rivière <nudz@...207...>, Yann Cointepas <yann@...225...> and Benjamin Thyreau <Benji2@...226...> recently worked on some enhancements to ipython to support Qt threading (like we do for GTK and WX). In the process, they made some fixes to the Qt backend and sent me this, which I hope the powers that be can take a look at and include before the CVS tree diverges too far.

With these changes and the corresponding ones to ipython (not in CVS yet, give me a day or two), it becomes possible to use ipython to interactively drive Qt applications, including matplotlib interactive plotting with the QtAgg backend.

Cheers,

f
