From breed...@gmail.com on 2014-10-14T18:59:52Z This seems like low hanging fruit to fix. Can anyone reproduce the issue? |

From ccordoba12 on 2015-02-08T18:43:21Z Summary: Matplotlib backend in Mac can't be changed whe using PySide (was: Qt-Python binding library selection gets reset when preference pane is opened) |

From ccordoba12 on 2015-02-08T19:21:23Z About the Qt bindings: those are set automatically according to the ones found in your external interpreter. Since Canopy doesn't come with PyQt4 but only with PySide, that's why even if you change them, they are set back to the only available option.

From breed...@gmail.com on 2015-02-08T20:23:42Z Ok. That makes sense. I suppose it would be better if PyQt4 was grayed out if it is unavailable, but whatever. To get PyQt4 from Enthought, I have to have the non-free version of Canopy. I don't really feel like building it from source right now, so that means I am stuck with PySide. The confusing part is, everything works fine if I always remember to select "PyQt4" for Qt-Python bindings library selection before I close the preference pane. I can restart spyder repeatedly, and matplotlib.get_backend() returns 'Qt4Agg'. If I forget to select "PyQt4" for the Qt-Python bindings library, then matplotlib.get_backend() returns 'MacOSX'. So it seems like the backend can be changed when using PySide. |

From ccordoba12 on 2015-02-12T08:30:57Z @-breedlun: Forcing the MacOS backend when using PySide was an ugly hack of mine, sorry for that... It'll be fixed on 2.3.3 :-) |

What steps will reproduce the problem?
What is the expected output? What do you see instead?
Expected output is "PyQt4" Qt-Python bindings library selection. I see "PySide" instead.
Please provide any additional information below
. I have specified "Qt4Agg" for the matplotlib backend in Preferences -> Console -> external modules. If I do not do step
#6, I can restart Spyder as many times as I want and then run matplotlib.get_backend(), and I get "Qt4Agg". If I do step#6and restart Spyder, then matplotlib.get_backend() gives "MacOSX". Thus, I believe opening the preferences pane causes Spyder to switch from "PyQt4" to "PySide"Original issue: http://code.google.com/p/spyderlib/issues/detail?id=1987
