[Haskell-cafe] How do I sort items in a wxhaskell listCtrl?

[Tilmann]

Hi list,

I couldn't find any clues googling and turn to you in the hope that 
someone might point me in the right direction:

I found the function |listCtrlSortItems2| with type |ListCtrl a -> 
Closure b -> IO Bool| and |closureCreate| (which type is a bit 
involved..), but I have no idea how to use them..

In the end, I would like to have a listCtrl where clicking on column 
headers will sort the items and maybe even indicating sorting order with 
a little arrow.

Any help is really appreciated,

Tilmann
