get wxListCtrl from wxListItem?

get wxListCtrl from wxListItem?
Hopefully I’m just missing something obvious in the API…but how can I obtain a reference to the wxListCtrl from a wxListItem?

I’m trying to use an editable wxListCtrl (similar to the example in the wxDocs). I have a function bound to the wx.EVT_LIST_END_LABEL_EDIT action. I’d like to update a python object with the data from the listCtrl, but I can’t seem to find a way to link back to my python data object from the wxListItem (which I obtain from event.GetItem() ). If I could get the wxListCtrl from the wxListItem…then it should be fairly straightfoward to store the python object in a derived class.

Any thoughts or alternative approaches appreciated - thanks,

Andrew
