reusing the pylab gui in a custom application (wxpython)?

Vlastimil_Brom · July 29, 2012, 10:14pm

Hi all,
I'd like to ask about the possibility to eventually reuse the gui of
pylab for showing and manipulating the plots in the custom application
(written in wxpython).
Basically, I'd like to add some application specific controls to the
toolbar, or to place the existing gui to a custom frame, which would
add such additional controls (slider, buttons, etc.)
I looked at ...
Python27\Lib\site-packages\matplotlib\backends\backend_wx.py , but
couldn't find any way to access this windows in custom code.
Would it be possible at all, or are there other options? Is there
maybe some equivalent class/module etc. which could be reused or
adapted?
Or is the only way to reimplement the functionality writing my own
plot gui (or to have the additionally needed controls in a separate
window, which doesn't look very elegant, but could probably work).

Thanks in advance for any hints
regards
Vlastimil Brom

Absolutely! It is one of the things mpl does best. Do a search in the online documentation for “embedding codex”.

I hope that helps!

Thanks for the quick response and a useful hint!

I apparently didn't search for the right terms before...
I turns out, that
http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_wx2.html
shows exactly, what I need.

By the way is there a place to propose a small correction of the example code?
namely
self.SetBackgroundColour(wx.NamedColor("WHITE"))

causes an error in wxpython 2.9, which removed the "...Color" aliases
and only knows "...Colour"
hence:

self.SetBackgroundColour(wx.NamedColour("WHITE"))

works in wxpython 2.9 and should be backwards compatible too.

Thanks again,

Thanks for catching that mistake. Unfortunately, we don’t do a good enough job of keeping up to date on changes in various backends. The best way to make sure that gets fixed is to send us a pull request on github. At the very least, post an issue report on it.

Thanks, I created an issue:

github.com/matplotlib/matplotlib

some matplotlib examples incompatible with wxpython 2.9

Hi, I noticed some compatibility problems while trying several code examples fro…m the matplotlib web with wxpython2.9, some of them might be quirks on the wxpython site, which might be fixed there, however, in some cases an adaption for this newer versin would be necessary. There were e.g. some cleanups and some name aliases have been removed, such as those containing ...Color... I noticed this in wx.NamedColor, which appears in: http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_wx2.html http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_wx4.html http://matplotlib.sourceforge.net/examples/user_interfaces/mathtext_wx.html http://matplotlib.sourceforge.net/examples/user_interfaces/wxcursor_demo.html A simple change to wx.NamedColour should be backwards compatible, as there are both names available in the previous version. I also encountered problems with some parts of the wx backend, which don't appear in wxagg i.e. the workaround is currently to replace: from matplotlib.backends.backend_wx import NavigationToolbar2Wx with from matplotlib.backends.backend_wxagg import NavigationToolbar2WxAgg However, it is likely, that this will eventually be fixed in the source code, rather than in the examples. Unfortunately, I wasn't able to find the bug sofar. I am not sure, whether there are some more comprehensive search options available, e.g. searching for wx at http://matplotlib.sourceforge.net/search.html?q=wx only lists the backend files; however, there are clearly some occurrences at least in the code examples as well. regards, Vlastimil Brom

about this and also tried to send the pull requests about the four
"wx.NamedColor" occurrences I could find.
Unfortunately, I haven't any experiences with code management tools
and github infrastructure, I didn't mess something up.

Regards,
vbr
