Hi,
same problem with ipython 0.12 and matplotlib 1.1.1rc.
To recall, I'm trying to add a QT4 widget to a matplotlib figure (MPL is
using Qt4 as backend). However, in the attached example the widget callback
(or slot) is not called. Oddly, if I add the qt4 widget manually calling
qt4_interface() from ipython it works.
Basically I want to preserve the maplotlib+ipython interactive workflow,
but using some "enhanced" figures (i.e. mpl figure+qt4 widgets).
Thank you for any suggestion.
