+about the items when the control requests it. Virtual list control can be used
+as a normal one except that no operations which can take time proportional to
+the number of items in the control happen -- this is required to allow having a
+practically infinite number of items. For example, in a multiple selection
+virtual list control, the selections won't be sent when many items are selected
+at once because this could mean iterating over all the items.
Using many of wxListCtrl features is shown in the
\helpref{corresponding sample}{samplelistctrl}.
