Question

If I have a notebook with three spreadsheet widgets, what is the best way to have changes to the spreadsheet update a dictionary (or maybe an sqlite file?). Do all wx grid objects come with a built in dictionary related to the SetNumberRows and SetNumberCols? Basically I am looking for guidance on how to work with the user-input data from a spreadsheet widget, as in this example adapted from the tutorial on python.org:

class ExSheet(wx.lib.sheet.CSheet):     def __init__(self, parent):         sheet.CSheet.__init__(self, parent)         self.SetLabelBackgroundColour('#CCFF66')         self.SetNumberRows(50)         self.SetNumberCols(50)  class Notebook(wx.Frame):     def __init__(self, parent, id, title):         wx.Frame.__init__(self, parent, id, title)         nb = wx.Notebook(self, -1, style=wx.NB_BOTTOM)         self.sheet1 = ExSheet(nb)         self.sheet2 = ExSheet(nb)         self.sheet3 = ExSheet(nb)         nb.AddPage(self.sheet1, 'Sheet1')         nb.AddPage(self.sheet2, 'Sheet2')         nb.AddPage(self.sheet3, 'Sheet3')         self.sheet1.SetFocus()         self.StatusBar()

Use a wxGrid with a wxGridTableBase instead

Here is a simple example:

import wx, wx.grid  class GridData(wx.grid.PyGridTableBase):     _cols = 'a b c'.split()     _data = [         '1 2 3'.split(),         '4 5 6'.split(),         '7 8 9'.split()     ]      def GetColLabelValue(self, col):         return self._cols[col]      def GetNumberRows(self):         return len(self._data)      def GetNumberCols(self):         return len(self._cols)      def GetValue(self, row, col):         return self._data[row][col]      def SetValue(self, row, col, val):         self._data[row][col] = val  class Test(wx.Frame):     def __init__(self):         wx.Frame.__init__(self, None)         self.data = GridData()         grid = wx.grid.Grid(self)         grid.SetTable(self.data)         self.Bind(wx.EVT_CLOSE, self.OnClose)         self.Show()      def OnClose(self, event):         print self.data._data         event.Skip()  app = wx.PySimpleApp() app.TopWindow = Test() app.MainLoop()
