Could you please try to simply disable the "Matplolib" patch option? By default, Spyder is monkey-patching Matplotlib to ensure that the Qt backend is selected (and eventually to add the figure options toolbar button which has been integrated in Matplotlib v1.0).
We could separate the "set backend" part from the "options button" part in this monkey-patch because this is the latter which is responsible for this as it is importing PyQt objects (in Python 2.x, this selects by default the PyQt API v1) before the ETS toolkit try to select the PyQt API v2. Hence the warnings, and the traceback which simply means that with PyQt API v1, the nameFilters method returns a QStringList -which has no 'index' method- whereas it returns a Python list object with PyQt API v2 -- that is what pyface is apparently expecting. I've just filled out an issue for this: http://code.google.com/p/spyderlib/issues/detail?id=825 HTH Pierre Le 3 nov. 2011 à 20:59, Janwillem van Dijk <[email protected]> a écrit : > When I run this small script from the command line (ubuntu 11.10) all is good. > > from traits.etsconfig.etsconfig import ETSConfig > ETSConfig.toolkit = 'qt4' > print 'toolkit: ',ETSConfig.toolkit > from pyface.api import FileDialog, OK > fdialog = FileDialog(action='open files',title='Choose files to open') > if fdialog.open() == OK: > for fname in fdialog.paths: > print fname > print 'finished' > > However, when running from within Spyder 2.1.1 (F5) I get the error messages > shown below.
