Those of you who updated from mpl svn between last night and now, may have noticed that the pan/zoom/etc functionality was broken. Last night I factored out the callback event handler that we use to support the toolbar navigation into a reusable class in cbook. And I broke it.
It is now fixed in revision 3126. If you want to use something like this in your own code, it goes like so In [1]: from matplotlib.cbook import CallbackRegistry In [2]: signals = 'eat', 'drink', 'be merry' In [3]: def oneat(x): print 'eat', x In [5]: def ondrink(x): print 'drink', x In [6]: callbacks = CallbackRegistry(signals) In [7]: cid = callbacks.connect('eat', oneat) In [8]: cid2 = callbacks.connect('drink', ondrink) In [11]: callbacks.process('drink', 123) drink 123 In [12]: callbacks.process('eat', 456) eat 456 In [13]: callbacks.process('be merry', 456) In [14]: callbacks.disconnect(cid) In [15]: callbacks.process('eat', 456) In [16]: tmp = callbacks.connect('drunk', ondrink) ------------------------------------------------------------ Traceback (most recent call last): File "<ipython console>", line 1, in ?
