Change the image of a list item (listctrl)

[Donn Ingle]

Hello, me again.
I am going blue in the face trying to change the icon of an item in a list
control.

I have an Image list with two icons in it. It's assigned correctly.
The icons are all set in a loop like so:
        for p in pl :
            ipog = Pog ( p )
            try: #catch pogs that are not properly formed
                if ipog.isInstalled ( ): i = 1
                else: i = 0
                li = wx.ListItem  (  ) 
                li.SetImage  ( i ) 
                li.SetText  ( p ) 
                self.InsertItem  ( li ) 
Nevermind the fluff, the SetImage ( ) part works fine.

So, later, when I select an item and click a button, I want that item's icon
to change.
I am here at the moment, no change actually happens:
        ii = self.GetFocusedItem ( )
        i = self.GetItem ( ii )
        print "PRE:", i.GetImage ( )
        i.SetImage ( 1 )
        print "POST:", i.GetImage ( )

Any help ?
