Help with listctrl columns

If a user re-arranges the column order how do I save/retrieve that information so that the next time they run it the columns are in their chosen, not default, position?
Thanks.

GetColumnsOrder should return the order: wx.ListCtrl — wxPython Phoenix 4.2.0 documentation

Often, it’s easiest to find and try methods in a shell or the debugger.

E.g.

or Create and Use Source Code — wxGlade 1.0.0 documentation

Thanks, that’s it.
Originally I mis-read the docs and thought that SetColumnOrder affected only the header. Duh!
