ability to make TListView "virtual"

Description:

In porting a Delphi application to Lazarus, I noticed that the TListView component doesn't have the ability to be virtual, ie., the ability to set an OwnerData property and specify a handler for the OnData event. This is useful when using a listview to display a lot of data because you can keep the data in your own structures instead of forcing the listview to load it all into memory.

This would be a nice feature to have implemented.
