python - is it possible to set numbers as a string in a listctrl -
okay ran complications setting numbers in listctrl they're numbers in sql database , they're inserted strings... converted numbers automatically

strings when set entries, when refreshlist function called up, error calls setstingitem value price likely happen quantity also insists insert string , what's supplied isn't string.... ideas on how can work around this? couldn't find python documentation me
as mentioned, you'll want cast items strings. casting in item code it's done behind scenes. alternative might work sub-class wx.listctrl , override setter, think that's overkill when can in item class.
