Hello darkside,
maybe the following little examples helps you with disconnecting:
>--------------------------------------------------------------------------------
from pylab import *
def event_response(event):
print event.name
disconnect(cid)
subplot(111)
cid = connect('button_press_event', event_response)
show()
>-----------------------------------------------------------------------------
concerning opening of figures:
I think it is not possible to open a figure after the show()
( I asked some time ago with subject "open / close or set active figures
during mainloop", but unfortunately without response).
Maybe it would be sufficient for you to clean the figure or the axes
(pylab.clf/cla), resetting labels and use the same connected event several
times.
best regards,
Matthias
