They recycle the views, showing only views for the items that fit on screen and, maybe, a few extra at the edges. Using callbacks to get the view and bind the data for each one. There was a way to use Dolphin Smalltalk ListView to use its underlying SysListView32 in virtual mode (I can't find it now). There are HTML list widgets that also do that. Here is a case of how to it with C# <http://www.codeproject.com/Articles/42229/Virtual-Mode-ListView> Of course nothing of this helps you immediately, unless you're going to implement such virtual/recycling lists in Morph.
