Re: [matplotlib-devel] Backend for Pyside
Hello, This is not directly related to your patch but I would like to report here that I still have at least one issue on MacOs that prevent matplotlib to work with your pyside backend. Indeed current PySide version (1.0.2) have a bug on MacOS that seems to have been fixed recently: http://bugs.pyside.org/show_bug.cgi?id=809 But I will have to wait for next PySide release to confirm your pyside patch works on MacOs. Will test as soon as next pyside version is out and available on macports. I do not have time nor will to test with the latest current pyside head.

Re: [matplotlib-devel] Backend for Pyside
I've added some comments and tested against PyQt4 4.7.3 -- I don't have PySide installed, so I'll just assume it works there, too.

Re: [matplotlib-devel] figure error during python shutdown
I think this might have existed for a long time, but there just hasn't been much testing running Gtk without opening windows. There is a fix in this pull request. https://github.com/matplotlib/matplotlib/pull/106 Can you confirm it works for you? Mike On 05/05/2011 05:17 PM, Benjamin Root wrote: There seems to be an odd error that comes up when exiting python after using matplotlib with gtkagg backend. I only notice this error if I do not display the figure (i.e., only saving figures in a headless mode) and during the test. Also, this is with matplotlib master branch. I have not tested this with any other branch.
