- This method can only be used with virtual list controls. It is used to indicate
- to the control the number of items it contains. After calling it, the main
- program should be ready to handle calls to various item callbacks (such as
- wxListCtrl::OnGetItemText) for all items in the range
- from 0 to @e count.
