You are mixing apples and oranges...  In report mode an item is the 
whole row so first you insert the item and then you can set the text for 
the other columns of the same item.  Since the API of wx.ListCtrl is so 
strange (thank you Microsoft) this fact can easily be confused or lost. 
   So normally you would use one of the the Insert*Item methods to add 
the new item and then one of the Set*Item methods to set the text for 
the other columns of the same item.  Since you are using the plain Item 
version of the methods then you can save the return value of InsertItem 
so you know what the ID (the index) of the item is, and then set the ID 
and col in the wx.ListItem you pass to SetItem for the other columns.

The InsertColumItem is for inserting a new column for the whole wx.ListCtrl.
