wxGrid, PyGridTableBase, strange SWIG error message!

[Laszlo Nagy]

I'm trying to create a special widget that is a wx.Grid and also a 
PyGridTableBase. In my special case of application, I really need to 
have a grid that uses itself for getting cell data and cell attributes.

Here is a test program, demonstrating my problem:

import wx
from wx.grid import Grid,PyGridTableBase

class SpecialGrid(Grid,PyGridTableBase):
     def __init__(self,*args,**kwargs):
         PyGridTableBase.__init__(self)
         Grid.__init__(self,*args,**kwargs)
         self.SetTable(self)

     def SetTable(self,table):
         if table is not self:
             raise Exception("Grid must be its own table!")
         else:
             PyGridTableBase.SetTable(self,self,takeOwnership=False)

app=wx.App(redirect=None)
frame=wx.Frame(None)
g = SpecialGrid(parent=frame)
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(g,1,wx.EXPAND)
frame.SetSizer(sizer)
frame.Show()
frame.Maximize()
app.MainLoop()


This program throws:

Traceback (most recent call last):
   File "test.py", line 18, in <module>
     g = SpecialGrid(parent=frame)
   File "test.py", line 6, in __init__
     PyGridTableBase.__init__(self)
   File 
"/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/grid.py", line 
910, in __init__
     self._setOORInfo(self);PyGridTableBase._setCallbackInfo(self, self, 
PyGridTableBase)
   File 
"/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 
3886, in _setOORInfo
     val = _core_.EvtHandler__setOORInfo(*args, **kwargs)
TypeError: in method 'EvtHandler__setOORInfo', expected argument 1 of 
type 'wxEvtHandler *'

This makes no sense to me. If I swap the constructor calls:

     def __init__(self,*args,**kwargs):
         Grid.__init__(self,*args,**kwargs)
         PyGridTableBase.__init__(self)
         self.SetTable(self)

Then I get this:

Traceback (most recent call last):
   File "test.py", line 18, in <module>
     g = SpecialGrid(parent=frame)
   File "test.py", line 7, in __init__

   File

     self._setOORInfo(self);PyGridTableBase._setCallbackInfo(self, self, 
PyGridTableBase)
   File 
"/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line

   File

     raise PyDeadObjectError(self.attrStr % self._name)
wx._core.PyDeadObjectError: The C++ part of the SpecialGrid object has 
been deleted, attribute access no longer allowed.

What the heck?

Thanks,
