This totally untested but I think I would try to sub-class something like
this:
class SpecialBoolCellRenderer(wx.grid.GridCellBoolRenderer):
def Draw(self, grid, attr, dc, rect, row, col, isSelected):
self.super()
do what ever is needed!
You have access to the row, col to determine value.
you might have to do:
def Clone(self):
return SpecialBoolCellRenderer()
Don't forget do something like
col.CustomRendererClass = SpecialBoolCellRenderer
Like I said this has not been tested and I could be way off with my thinking.
