The grey square is due to using "xpm" file formats for the button images 
(disabled state).
Attached is a version backend_wx.py which uses "png" files for the
"back" and "forward" button. In theory this should show a black & white
version of the button when it is disabled (applying the alpha channel,
only supported by wx with png files).
However for whatever reason this does not work with matplotlib's
toolbar, it works very nicely when I create a test toolbar (see the
image sent with my previous mail on this thread, or run the attached 
wx_cursor_demoToolbar.py using the attached backend_wx.py).
I tried to narrow it down but but up to now without any luck.
I attached a demo file which shows how the button should look (hacked 
together toolbar with only back and forward button). If you change the 
two lines below in the demo (comment the myadd_toolbar line and 
uncomment the other one you will get the normal matplotlib toolbar, but 
the disable button stuff doesn't work.
## self.add_toolbar() # comment this out for no toolbar
 self.myadd_toolbar()
Maybe someone else who know matplotlib better then I do might have an 
idea on what is going on.
See you

 Hello,
I tried to use one of my script and I obtain this error.
I tried the cvs (above for the version) and the matplotlib 0.81 and both 
have the problem.
It's just a typo in the file artist.py line 407.
return geto(o, *args, **kwargs)
must be replace by:
return getp(o, *args, **kwargs)
regards,
N.

Keith: You are freetype package is too old, you need 2.1.9 or newer.

Hi all,
well, I'm sorry to wake up an old thread, but what if there are subplots in 
the figure ? I tried to ask
 axes([0.1, 0.1, 0.9, 0.9])
before specifying my subplot()s, but it changed nothing.
How to reduce the margin of the whole figure when it has subplots ?
Cheers,
Nicolas

I got these errors doing "python setup.py build" on my redhat 9 system =
using python 2.4.
