[Matplotlib-users] ipython threading fails with macosx backend
Hi, I'm using ipython 0.9.1 with the svn version of matplotlib on 64 bit python on mac os x 10.5.7. I have only been able to get python-64 running with the MacOSX backend; all of the others (wxpython, gtk, qt, tk) have failed for one reason or another. I've tried ipython without any flags and importing pylab on the command line: from pylab import * and ipython -pylab, and then plotting from a script. I retain access to the command line unless I type show() at the command line, at which point I can't return to the command line unless I close all of my graphics windows. I don't have this problem when running 32 bit python with qt or tk as the backends. Is this an error? Should there be a command-line flag for ipython to start threading for MacOSX specifically?

Re: [Matplotlib-users] ipython threading fails with macosx backend
The Mac OS backend is fairly new, and I don't believe any of the backend-specific threading code that ipython requires has been implemented for the OS-X backend. Just wanted to drop a note to say it's probably not you. But as a non-Mac user, I may be wrong, and I hope to be corrected :) Michiel: any idea how much effort would be involved here?

Re: [Matplotlib-users] ipython threading fails with macosx backend
As I understand it the Mac backend uses the PyOS_ImputHook trick, which means that no custom threading code is needed in IPython. Thus it should just work without any threading flags in both IPython *and* regular python. Just as an aside, wx is the only GUI toolkit that doesn't support this new type of interactive usage. We (ipython devs) are working with the wx devs to change that. Once that is done, we should be able to get rid of all the nasty threading code in ipython. More details will follow.

Re: [Matplotlib-users] ipython threading fails with macosx backend
OK, thanks. I don't really know why it's failing, but I'm going to continue trying to get other backends installed to test them. I also now have independent reasons not to use the MacOSX backend: Thu Jul 2 14:51:48 Python-64[56094] Error: CGContextSetLineDash: invalid dash array: negative lengths are not allowed. I can't draw dashed lines.

I can't draw dashed lines. In principle, you should be able to draw dashed lines with the MacOSX backend. Can you post a complete script that triggers this error?

Trying to plot anything with any dashed pattern causes the error: Python 2.6.2 (r262:71600, Jun 20 2009, 12:18:19) Type copyright, credits or license for more information.
