setitem on column

Hi List,

I want to set a certain cell in a ListCtrl to Red. I am using the following
code to establish this:

                i = self.GetItem(self.n, colnr)
                self.SetItem(i.SetTextColour(wxRED))

However doing this gives me the following Traceback:

Traceback (most recent call last):

    self.SetItem(i.SetTextColour(wxRED))

SetItem
    val = controls2c.wxListCtrl_SetItem(self, *_args, **_kwargs)
TypeError: Type error in argument 2 of wxListCtrl_SetItem. Expected
_wxListItem_p.

I have been googling around, and I can't find anything that is giving me
directions here.

Cheers,

The call to i.SetTextColour(wxRED) returns None, since you are simply
setting the color of the item. So your second line is essentially
calling self.SetItem(None).

Try breaking up the steps:

                 i = self.GetItem(self.n, colnr)
                 i.SetTextColour(wxRED)
                 self.SetItem(i)
