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 @a count.
Notice that the control is not necessarily redrawn after this call as
it may be undesirable if an item which is not visible on the screen
anyhow was added to or removed from a control displaying many items, if
you do need to refresh the display you can just call Refresh() manually.
