Possible to update a wxTextCtrl from inside a wxGrid

I Fixed it...I just needed to "read" the error message to figure out what was happening.

The problem was that :
  - "CSheet's parent was the panel "self.Item_tab" and
  - "self.Item_tab"s parent was the panel "self.notebook" and
     - "self.notebook"s parent was "self.panel_main" and
  - "self.panel_main" parent was "class BOLFrame's" frame

( see the sudo code below for the details)

To fix it I rearranged some code and added on line of code. The code in class BOLFrame not looks like this:

  ...
  self.tcTotalWeight = wxTextCtrl(self.Item_tab, -1, "") # create the text control
             self.Item_tab.tcTWeight = self.tcTWeight # give the "parent" self.Item access to it
  self.grid = SheetBOL(self.Item_tab) # now, create the grid
  ...

···

           self.Item_tab = wxPanel(self.notebook, -1)
