[wxPython] Changing Grid Cell Colors

[Gabe Ycas]

Hello, all. I have been playing with wxGrid and just can't figure out
how to
get wxGrid to do what I want. I am trying to make rows and/or cells
change background color
as the user changes cells (when a cell is changed its row's background
also changes). I
cannot, however, get the background to refresh. When
wxGrid.SetCellBackgroundColor() is
called the background color doesn't change unless the cell need be
redrawn (after it is
selected of edited). wxGrid.ForceRefresh() doesn't exist (it's not even
in wxGTK) and Refresh()
doesn't work. How can I get this to work?

Thanks,
Gabe Ycas

This reminds me, that I asked a related question with no response:
