Question about ColumnSorterMixin.SortListItems()

I successfully setup a list with the ColumnSorterMixin and it works
fine,
however I want the list to sort automatically when my PopulateList()
method is
run. My problem is what instance to send SortListItems(). It seems if
I try to
send 'self' (my frame) or 'self.list', I get an attribute error:

  File "Z:\Colin's Work\Code\spyditor\main.py", line 188, in
PopulateList
    ColumnSorterMixin.SortListItems(self.list)
  File "C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\lib\mixins
\listctrl.
py", line 78, in SortListItems
    oldCol = self._col
AttributeError: 'List' object has no attribute '_col'

Again this is occuring with either my mainframe or my list as a
reference,
and also the sorting is working normally for the column click. What
am I doing
wrong?

It looks like the mixin is sorting the ListCtrl itself. If I were you,
I would do the sorting of the data myself before putting it into the
ListCtrl.

self.SortListItems(self.lcSortCol, self.lcSortOrd)

"self" is the panel which is inherits from "ColumnSorterMixin",
"lcSortCol" is the zero based index of the column and lcSortOrd is
either True / False.

Hope this helps
