Robin,

   It should be. The last time I edited that page was 2007-09-01, and it's
worked flawlessly with Python-2.4.3 and wxPython-2.8.0.1. I upgraded the
distribution on the notebook so it's running Python-2.5.1 and
wxPython-2.8.6.1.

   The code at the top of the module is:

class dataTable(wx.grid.PyGridTableBase):
   data = appData.altData
   rowLabels = ()
   colLabels = ()

   def __init__(self, data, rowLabels=None, colLabels=None):
     wx.grid.PyGridTableBase.__init__(self)
     self.data = data
     self.rowLabels = rowLabels
     self.colLabels = colLabels

   def GetNumberRows(self):
     if self.appData.projname != ' ':
       self.appData.cur.execute("select count(*) from Variable")
       self.nRows = self.appData.fetchall()
       return self.nRows
     else:
       return 24

   def GetNumberCols(self):
     # return len(self.data[0])
     return 33

   ...

class modData(wx.Panel):
   def __init__(self, prnt, ID):
     wx.Panel.__init__(self, prnt, wx.ID_ANY)

     self.SetHelpText('Enter, edit, and remove existing condition data and alternatives here.')

     topLevelBox = wx.BoxSizer(wx.VERTICAL)        # Base container for all widgets
     outerBox = wx.BoxSizer(wx.VERTICAL)           # Adds to space around widgets
     buttonBox = wx.BoxSizer(wx.HORIZONTAL)        # For the Save button; allows placement across
     widgetBox = wx.BoxSizer(wx.VERTICAL)          # Holds grid and save button

     # Here's where the grid widget is defined.
     self.dataGrid = wx.grid.Grid(self, size=wx.Size(770,440))
     table = dataTable(self)
     self.dataGrid.SetTable(table, True)

     # simple cell formatting
     for i in range(0,34):
       self.dataGrid.SetColSize(i, 125)

     self.dataGrid.AutoSizeColumns(setAsMin=True)

   GetNumberCols() returns 33, and setColSize() matches that.

Thanks,

Rich
