I need to display a quite large number of data in a list control and use the ‘items’ attribute for that purpose. However, I’m not content with the speed of this solution and would like to use a ‘virtual’ list control instead, as it is described here: 
The problem is, that the necessary constants and functions (i.e. wxLC_VIRTUAL) are not defined by wxHaskell. Is there a technical reason for this or could they be added easily?
