Hi,
I am still getting crashes using the WX backend with the latest SVN.
For example:
In [1]: figure()
------------------------------------------------------------
Traceback (most recent call last):
File
"/usr/lib/python2.5/site-packages/matplotlib/backends/backend_wx.py",
line 1092, in _onSize
self.draw()
File
"/usr/lib/python2.5/site-packages/matplotlib/backends/backend_wx.py",
line 892, in draw
self.figure.draw(self.renderer)
File "/usr/lib/python2.5/site-packages/matplotlib/figure.py", line
724, in draw
if self.frameon: self.patch.draw(renderer)
File "/usr/lib/python2.5/site-packages/matplotlib/patches.py", line
257, in draw
gc = renderer.new_gc()
File
"/usr/lib/python2.5/site-packages/matplotlib/backends/backend_wx.py",
line 366, in new_gc
self.gc = GraphicsContextWx(self.bitmap, self)
File
"/usr/lib/python2.5/site-packages/matplotlib/backends/backend_wx.py",
line 463, in __init__
gfx_ctx = wx.GraphicsContext.Create(dc)
<type 'exceptions.AttributeError'>: 'module' object has no attribute
'GraphicsContext'
It appears that this GraphicsContext either isn't in my version of
wxPython or isn't initialized properly. Updating to wxPython 2.8 fixed
the problem, but I think that breaks other things on my system (like
system tools on Ubuntu that I need to use). For now I will just use
2.8, but I may have to revert. Is supporting wx 2.6 a goal?
Cheers,
David
