Crash on pyplot demo

wxPython Users

Hi,

I have just installed "wxPython3.0.2.0 " on the latest python2.7.x (python-2.7.9) and then installed the wxPython3.0-win32-docs-demos.exe

to run the demos of WXPython. I tried the pyPlot demo, but this demo crashes with this error message.

python “G:\wxPython3.0 Docs and Demos\demo\PyPlot.py”

Python 2.7.9 (default, Dec 10 2014, 12:28:03) [MSC v.1500 64 bit (AMD64)]

wx.version: 3.0.2.0 msw (classic)

Traceback (most recent call last):

File “G:\wxPython3.0 Docs and Demos\demo\PyPlot.py”, line 34, in OnButton

win = wx.lib.plot.TestFrame(self, -1, "PlotCanvas Demo")

File “G:\Python64\lib\site-packages\wx-3.0-msw\wx\lib\plot.py”, line 2309, in init

self.client = PlotCanvas(self)

File “G:\Python64\lib\site-packages\wx-3.0-msw\wx\lib\plot.py”, line 599, in init

self.GrabHandCursor = wx.Cursor(GrabHand.GetImage())

File “G:\Python64\lib\site-packages\wx-3.0-msw\wx_gdi.py”, line 1547, in init

_gdi_.Cursor_swiginit(self,_gdi_.new_Cursor(*args, **kwargs))

TypeError: Required argument ‘type’ (pos 2) not found

I wonder if any one can help me to resolve this problem to let this demo work. Or if you know any compatible version between wxpython and python, at least for this demo?

Thanks

Masoud

Hhm, in my copy of 3.0.2 line 599 of plot.py is:
self.GrabHandCursor = wx.CursorFromImage(GrabHand.GetImage())
But I noticed a few other things in the demo which seem to have
slipped in from the Phoenix version of it and need to be changed,
see attached patch.
After these changes the demo works for me on Python 2.7 (32bit) with
3.0.2 classic wxPython on Win8.

I borrowed the time machine again and fixed those 23 and 9 days ago :wink:

So this bug still exists in the wilds of downloadable-installers… the fix seems to be to download and replace the plot.py with the latest (now 10 months old) from git. At least that seems to be working for me. Did I miss any steps, or overlook something that might still be broken?
