wxWidgets issue

[Anthony Lenton]

Hello list,
On my machine you can't bring up the Classification Generation Dialog
without getting a traceback.
This is the traceback:

Traceback (most recent call last):
  File "/home/anthony/svn/thuban/trunk/thuban/Thuban/UI/classifier.py",
line 1057, in _OnGenClass
    internal_from_wxstring(self.fields.GetString(self.__cur_field)))
  File "/home/anthony/svn/thuban/trunk/thuban/Thuban/UI/classgen.py",
line 111, in __init__
    obj = clazz(self, self.layer, self.fieldName, self.fieldType)
  File "/home/anthony/svn/thuban/trunk/thuban/Thuban/UI/classgen.py",
line 412, in __init__
    self.numGroupsCtrl.SetRange(1, sys.maxint)
  File "/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/_controls.py",
line 2265, in SetRange
    return _controls_.SpinCtrl_SetRange(*args, **kwargs)
OverflowError: in method 'SpinCtrl_SetRange', expected argument 3 of type 'int'

I suspect this is because my python is aware of the 64-bit hardware
it's running on, but wx has been compiled for 32 bits.  I don't know
if there's a way to ask wx which is the maximum integer it'll accept
as an argument, but this fixes it anyway:
